Q: The rocks around here are full of fossils, although they are not
dinosaurian, just tiny marine stuff. A common fossil (assuming it is a fossil, it sure
looks like it) is a small circle, a few millimetres across, with a hole in the middle and
fine lines around the outside. It looks very much like a little pineapple ring. Is this
some type of shell segment? There are also some obvious seashells, and trilobites,
although I have not been lucky enough to find one of those. Thanks in advance.
from Brad M., Woodville, Ontario, Canada; February 27, 2000
A: You're certainly lucky to be in an area with a lot of fossils. You might try your local library; there are a lot of good fossil guide books available. One nice one is the Eyewitness Handbook of Fossils (by C. Walker and D. Ward), the pictures are very clear and there is a lot of information on each of them.
Q: how many years did dinosaurs live on earth ?
from Josiah H., Vineland, NJ, USA; February 27, 2000
A: They lived from about 230 million years ago until 65 million years ago, a total of 165 million years.
Q: How do palentologists know where to look for dinosaur fossils?
from Myles G., Seattle, WA, USA; February 27, 2000
A: They don't. Paleontologists often search for years without finding interesting fossils.

was the first Diplodocus fossil found? Where did it live when it was alive? What are some
other dinosaurs of the same period? Thanks for the info
from erin s.; February 27, 2000
A: For information on Diplodocus, click here. For other dinosaurs that lived during the late Jurassic Period in North America, click here and go to the section on North America.
Q: Did Dimetrodon have sharp claws?
from Rosey I, Hunter, NY, USA; February 27, 2000
A: Yes, Dimetrodon had sharp claws on its four feet.
Q: Isn't the littlest dinosaur a mosaurus? [ by the way i dont know how to
spell it.]
from Marain O., Wilton, CT, USA; February 27, 2000
A: Mussarus is tiny (16 inches long 37 cm), but is a only a hatchling, not an adult specimen. No one knows how big an adult would grow to be.
Q: Did the little bumps on the snout and behind the dome of Pachycephalosaurus
have a purpose? Did they support horns (like on Stygimoloch.)? I am also curious about you response to my sauropod skull question. One of my books, DINOSAUR! (based on the tv documentary) by David Norman says that the Brachiosaurus' skull was 3 feet or 0.9 metres long, which is bigger than your Nemegtosaurus. What was your source? PS. Anybody know how big that Argentinosaurus skull was (there's a picture of it in the Dec. 1997 National Geographic, and it looks kind of low and small.)?
from Brad M., Woodville, Ontario, Canada; February 27, 2000
A: My reference for that answer was the book, "The Evolution and Extinction of the Dinosaurs" by David E. Fastovsky and David B. Weishempel, Cambridge University Press, 1996. They may have been presenting an average skull size (they don't say). I'll check out the Norman book.
I don't have figures on Argentinosaurus, and I've never seen any definitive explanation for Pachycephalosaurus' bumps.
Q: I am doing a report and was wondering what type of fossils have been found
in New York State? They can be dinosaur fossils or any other type of fossils. If you do not have an answer to this question, will you suggest a few websites that may help? Thank you.
from Jana, NY, USA; February 27, 2000
A: There have been no dinosaurs found in New York State (yet). For a page of dinosaurs fossils found in each state of the USA (and the official sate fossil of each state), click here.
Q: What is the suborder of the Protoceratops?
from Annie S., W. Milford, NJ, USA; February 26, 2000
A: Protoceratops belong to the suborder ceratospia - frilled dinosaurs.
Q: In what periods did the dinosaurs live(how did you name it)?
from DARREN, CP. WC; February 26, 2000
A: They lived during the Mesozoic Era, which is divided into theTriassic period, the Jurassic period, and the Cretaceous period.
Q: I am in the 8th grade, doing a report on the Hadrosaurus. These are a few questions I have not been able to find an answer for. What were the main enemies of the Hadroaurus? What are the similarities between the Hadrosaurus and creatures today? How long did they live for? How did they treat their
young.
If you could answer any of these questions A.S.A.P it would be a great help to me. Thanks
from Elliot G., West Orange, New Jersey, USA; February 26, 2000
A: Very little is known about Hadrosaurus, since only a very incomplete skeleton was found. This duckbilled dinosaur dates from the late Cretacesou period and lived in what is now North America. It was probably eaten by any of a number of theropods, perhaps Diplotomodon or Dryptosaurus. For other dinosaurs that lived during the late Cretaceous, click here. For the similarities between Hadrosaurus and modern-day animals, you'll have to read the entry on Hadrosaurus and draw your own conclusions. There is no fossil evidence on how Hadrosaurus cared for its young.
Q: Can you give me the nickname of the Ankylosaurus?
from Becky H., West Milford, New Jersey, USA; February 26, 2000
A: I've never heard of a nickname for Ankylosaurus, but the name ankylosaurus means "Fused Lizard," because many of its bones were fused together
Q: Hi- I need to find a dinosaur that lived in the triassic period can you please tell me where on this website i can find one with info. about it? Thank you very much!
from Melissa T., Miami, FL, USA; February 26, 2000
A: For Triassic dinosaurs, click here.
Q: How do you know what the skin color looked liked or how the skin felt.
from Vincenz F., Bronx, NY, USA; February 26, 2000
A: No one knows what color any of the dinosaurs were, but many fossilized skin impressions have been found. For example, T. rex skin had a "pebbled" texture. For more information , click here.
Q: I am doing a report on the Pachycephalosaurus and have a few questions.

Q: what caused the extinction of the protoceratops and the diplodocus?
from SAMANTHA, CUMBERLAND, RI, USA; February 26, 2000
A: Protoceratops went extinct during the K-T extinction 65 million years ago. Diplodocus lived much earlier, during the late Jurassic period. Diplodocus went extinct about 145 million years ago - during a smaller mass extinction which marked the end of the Jurassic.
Q: WHAT ARE SOME OF THE DINOSAURS OF THE SIMILAR SPECIES OF PROTOSERATOPS? THIS
IS A ? FOR A 7TH GRADE REPORT DUE FEB.28
from SAMANTHA, CUMBERLAND, RI, USA; February 26, 2000
A: Protoceratops is a genus of dinosaurs, not a species. It belonged to the group of dinosaurs called ceratopsians, that included many genera (the plural of genus), including Triceratops, Pentaceratops, Montanoceratops, Monoclonius, Styracosaurus, Zuniceratops, and many others. Ceratopsians were quadrupedal plant-eaters who had a beak, a bony neck frill, and horns.
Q: WHAT ARE SOME OF THE DINOSAURS [NAMES] IN THE PROTOCERATOPS TIME?
from SAMANTHA; February 26, 2000
A: Protoceratops lived during the late Cretaceous period (about 72 to 65 million years ago) in what is now Mongolia, Asia. For a list of other dinosaurs that lived in Asia during that time, click here and scroll down to the orange section (Asian dinosaurs form the late Cretaceous period).
Q: Which sauropod had the biggest head (Not in relation to body size or anything, just the actual measurement.)?
from Brad M., Woodville, Ontario, Canada; February 25, 2000

Q: I am in first grade and am doing a report on carnivores. I decided to do it on theropods since dinos are the coolest and i am going to be a paleontlogist. I am looking for a short, complete definition of a theropod. Can you help. thanks, Noah P.S. see you in about 13 years.
from Noah D., Howell. MI, USA; February 25, 2000
A: Theropods are a suborder of saurischian dinosaurs. They were fast-moving, bipedal carnivores (meat-eaters) with grasping hands and clawed digits. Theropods lived from the mid-Triassic period until the end of the Cretaceous period. The word theropod means "beast-footed".

Q: What kind of tools do they need to dig up a dinosaur?
from Alanna S., Alberta, Canada; February 25, 2000
A: Click here for information on excavating fossils.
Q: Why does T-rex have a better advantage over other meat-eaters?
from Jon M., New York City, New York, USA; February 25, 2000
A: Mostly because T. rex was bigger that any of its contemporaries. It was also smarter than many, but not all.
Q: DO YOU HAVE ANY PICTURES OF LESOTHOSAURUS'S?

A: For a small drawing of Lesothosaurus and information about it, click here.
Q: Ok, I've asked some weird questions in the past, but this one is relatively
normal. What's the status of the Oviraptor skull with the horn on its nose? Do they now think it is a female Oviraptor, or a different species from the one with the cassowary crest, or was it simply based on a damaged skull with the crest broken off? The reason I asked weird questions is I'd like to someday publish a book on dinosaurs and would like them as accurate as possible. (Which is impossible in itself.)
from Mary N., Georgia, VT, USA; February 24, 2000
A: Oviraptor philoceratops (which was found with a crushed skull in southern Mongolia in 1923 by George Olsen) had a small, horn-like projection at the tip of the snout (that looks like it was broken, but may have actually looked that way). This projection may have been part of the bony nasal crest or may have been a horn. There isn't a definitive answer to this question. Good luck with the book!
Q: How did T-Rex get its name?
from Alex Y., Apex, NC, USA; February 24, 2000

Q: Did dinosaurs have a crop ( a bunch of stones at the base of the throat for grinding food)???
from Paul, Chambersburg, PA, USA; February 24, 2000
A: Some dinosaurs had a gizzard, a muscular, often pebble-filled pouch in the stomach that helps grind up food. Gastroliths (gizzard stones) have been found in many dinosaur fossils. The crop is a pouch in the throat where food can be temporarily stored and preliminary food breakdown happens, but I it doesn't contain stones.
Q: I heard there whas found a new dinosaur. I heard it was the biggest one they ever found (50m). I must to know if it's true.

Q: what does the word fossil mean in Latin?
what determines a fossil's color?
from School, Bitburg, Germany; February 24, 2000
A: Fossil comes from the Latin word "fodere," which means "to dig." What determines a fossil's color is the composition of the minerals that formed it.
Q: WERE DINOSAURS MOSTLY HERBIVORES OR CARNIVORES?
from KRISTEN, DELRAN, NJ, USA; February 24, 2000
A: THere were many more herbivores than carnivores. For more information on dinosaur diets, click here.
Q: Which dinosaurs had blood pressure problums?
from Chris G., Havana, Illinois, USA; February 24, 2000
A: The giant, long-necked sauropods had to have high blood pressure in order to pump blood up the long neck to the brain.
Q: Why don't dinosaurs have ears?
from Matthew L.. Clearwater, FL, USA; February 23, 2000

A: The earliest dinosaurs date from about 230 million years ago (during the mid Triassic period).
Q: How did different dinosaurs adapt to different environment
thoughout the world and during different periods? Please give examples.
from joshua R, Houston, TX, USA; February 22, 2000
A: This sounds suspiciously like a homework question. To answer it, pick two vastly different dinosaurs, like Massospondylus (an early, medium-sized plant-eater from a desert-like environment in the Triassic period) and T. rex (a huge meat-eater which lived in the cooler late Cretaceous period). Or choose dinosaurs like Baryonyx, which ate fish (with sharp teeth) and lived near rivers during the early Jurassic period or a giant sauropod liek Brachiosaurus which had a long neck, presumably eat the tops of tall trees.
Q: Did the Stegosaurus have a nickname?
from Allison C., Cornell, Illinois, USA; February 22, 2000
A: It soesn't have a nickname in everyday English, but there was a Stegosaur in the children's cartoon movie Land Before Time, and I don't remenber if it had a nickname there.

from Ashley, Port Deposit, USA; February 22, 2000
A: The Cenozoic Era lasted from 65 million years ago until today. Some Cenozoic animals include us (and everything else alive today), and all the organisls that have lived on Earth since the time immediately following the K-T extinction 65 million years ago. A sampling of these animals includes smilodon, mammoths, Basilosaurus (a primitive whale), and many more. For more detailed information on these and other geologic eras, click here.
Q: In the Precambrian Era,what are some specific names of the animals?
from Heather, M.D., USA; February 22, 2000

dinosaurs in general. Given the continental u.s. , what would have been average
numbers?
from jimmy r., plainfield, il, USA; February 16, 2000
A: This is a question that a lot of people would like to know the answer to, but no one knows how to figure out the answer to this yet. All we know is how many fossils have been found, and not how many fossils there are, and what percentage of an average population fossilizes (which probably varies videly from species to species).
Q: You haven't answered a SINGLE question during the past week.
from Jimmy L., Georgia, USA; February 16, 2000
A: Yes I have, you're probably going to a our old numerical IP address (instead of using our domain name, www.ZoomDinosaurs.com). Every machine on the Internet has a numerical IP (Internet protocol) address, and we transferred all our files onto a new machine (which has a different IP number), so you're not getting anything new, like our new contest, which I thought you would win, but didn't! I'll upload this file to our old machine so you see this.

from Farris P., Fremont, CA, USA; February 15, 2000
A: Unlike most other animals, dinosaurs are known by their scientific name (their genus). For example, the genus of Triceratops is Triceratops. There is some disagreement about how many species of Triceratops have been found. Some
paleontologists (notably Ostrom and Welnhoffer, 1990) believe there is one species, Triceratops
horridus. Others believe that there are two (C. Forster, 1996) or more species, including: Triceratops
horridus, Triceratops prorsus, Triceratops albertensis, Triceratops ingens, Triceratops alticornis, and
perhaps others.

from Gary G., New Rochelle, NY, USA; February 15, 2000
A: There was a mass extinction at the end of the Miocene, in which many animals, including Platybelodon, went extinct, perhaps because of changes in the weather.
Q: How did a lesothosaur dinosaur get its name?
from ?; February 15, 2000
A: The dinosaur Lesothosaurus was named for its fossils' location. Its name means Lesotho lizard; its fossils were found in Lesotho, South Africa. For more info on Lesothosauurs, click here.
Q: I have read that the "Mammal-like reptiles" were not reptiles at all. This is fine, but what are they then? This leaves too much unexplained.
- were they amphibians?
- were they mammals?
- did they fit into any class? They should, but since this is a relatively new
classification I can see how they may not.
- have mammals and proto-mammals been put into a new class together (Synapsida)
- did the synapsids evolve from reptiles? This would make sense to me, since I would assume the eggs of the platypus are hard-shelled. Even in non-egg-laying mammals, there are some hints of a reptilian egg in our distant past. I know this is zoomdinosaurs, but I couldn't find zoomprotomammals. Please help!
from Brad M., Woodville, Ontario, Canada; February 15, 2000
A: The so-called "mammal-like reptiles," or pelycosaurs (like Dimetrodon) were early synapsids. The name "mammal-like reptiles" is a misnomer for this group that split off from reptiles about 320 million years ago. They were not amphibians, but they were ancestors of mammals.

Q: How did the dinosaurs survive in the cold?
from Paul M., Caleb H., Clifford S., Parkersburg, WV, USA; February 15, 2000
Earth about 65 million years ago. |
A: During the Mesozoic period, when dinosaurs lived, the climate was warmer than it is now. Also, the continents were jammed together into a supercontinent (called Pangaea) that was located near the equator (even the continent of Antarctica was relatively warm). If there were any relatively cold area, dinosaurs could have migrated to warmed areas seasonally (although there wasn't much seasonality during the Mesozoic Era).
Q: What distinguishing or unusual features does an allosaurus have?
from Amber M., Tell City, , IN, USA; February 15, 2000

there later this year, and I would like to know if I will be able to see some
dinosaurs on my trip.
from Brad M., Woodville, Ontario, Canada; February 7, 2000
A: I don't think so (but I live thousands of miles away and haven't been to Quebec in over 20 years). According to "The Dinosaur Data Book" (1990, Avon Books) the Redpath Museum in Quebec has a few dinosaur fossil fragments, but they aren't on display (or at least they weren't when that book was written). Here's a site on Canadian museums; they might have the information you need.

Q: what year was the iguanodon discovered (its bones)? what are the relatives of iguanodon?? what were iguanodon's mating habits? PLEASE!!!!!!!HELP ME I'VE LOOKED EVERY WERE,BUT CANT FIND THIS INFO
ABOUT THE IGUANODON:ITS LIFE SPAN,MATING HABITS,ENEMIES,AND HOW LONG THEY LIVED SOMEONE
PPPPPPLLLLLLLLLEEEEEEEEEEAAAAAASSSSSSSEEEEEEE HELP!!!!
from nicole f., tampa, fl, USA; February 5, 2000
A: Iguanodon was named by Gideon A. Mantell in 1825. For more information on Iguanodon, click here. Other iguanodontids (relatives of Iguanodon) included Ouranosaurus, Probactrosaurus, Tenontosaurus, Rhabdodon, etc. No one knows about its mating habits or life span.
No one knows exactly which dinosaurs preyed upon Iguanodon, but you can guess, by looking up which meat-eating dinosaurs lived during the same time (the early Cretaceous period) and in the same area (North America and Western Europe). For its contemporaries, click here and scroll down to the sections on North America and Europe and find meat-eaters (listed in red) that were big enough to attack a 30-foot-long dinosaur (like Altispinax). Smaller meat-eaters might have hunted in packs, so some of the smaller ones may have preyed upon Iguanodon.
Q: Look at a question asked on February 3. It said that Stegosaurus lived in the late Jurassic period, 156-140 million years ago. However, the Jurassic was 206 to 144 and the period from 156 to 140 DOES contain 4 million years outside the Jurassic.
from Jimmy L., Georgia, USA; February 3, 2000
A: Stegosaurus probably went extinct at the end-Jurassic exitnction. Although the dates of the geologic periods are generally given as absolutes, they aren't (also, the dates for the beginning and end of the various periods vary from source to source - I use the figures from UCMP) and these figures change over time as more fossil information is interpreted. Pinpointing the end of a geologic time era is impossible; when does an ice age officially begin, or an extinction end? When a comet hits the Earth, is that moment the end of one age and the beginning of another, or do you wait until some extinctions occur (and if so, how many? There is a long fuzzy period between the various geologic time periods. The margin of error between ages is in the range of plus or minus 1 to 5 million years (which represents 2 standard deviations around the calculated mean - it may be bigger). Some sources, like the American Museum of Natural History put the end of Stegsaurus at 140 mya, other just say late in the Jurassic.
Q: What can you tell us about the extinction theory on mammals eating dinosuars eggs?

A: For information on this extinction theory and others, click here.
Q: Do you know when the Chirostenotes became extinct? Also do know who its
main predators? What about how it adapted to its environment? I hope you know. Thanks!
from Leah G., Teaneck, NJ, USA; February 3, 2000
A: Chirostenotes lived during the late Cretaceous period; it went extinct about 71 million years ago. To find possible predators (no one knows which animals preyed upon it, but you can guess, knowing its size, when and where it lived). Go to the page on fossils from the late Cretaceous, and scroll down to the yellow section on North American fossils (since Chirostenotes was found in Canada). The fossils in red were meat-eaters - you can decide which ones were likely predators of Chirostenotes (which was about 2 m long). Almost everything about an organism reflects an adaptation to its environment. For more information on Chirostenotes, click here.
Q: The stegasarous lived in wich years in the mezazoic era?
How much did the stegasarous weigh?
from Jason L., Beavercreek, Ohio, USA; February 3, 2000

Q: Last week I was looking up information for my 5-year-old, and I read a
short article entitled something like "Why is there no brontosaurus?", and I'm pretty sure I read it here (Zoom Dinosaurs). It went into detail of how the paleontologist
put the wrong head on an Apatasaurus and called it "brontosaurus". However, now I
can't find it anywhere! Where did it go? I need it to prove a point to a teacher.
Thanks in advance!
from Amy A-P, Mamaroneck, New York, USA; February 2, 2000
A: The original Brontosaurus fossil, found in 1879, lacked a skull (as many fossils do). Othniel Marsh added a skull found miles away (this skull did not belong to the Brontosaurus, but to a Camarasaurus). In 1900, Henry Osborn assembled another skull-less Brontosaurus at the American Museum of Natural History in New York City, adding a cast of Marsh's skull. In 1915, Earl Douglass of the Carnegie Museum found a Brontosaurus fossil that included a skull, but because of Osborn's influence, the Carnegie displayed the fossil skull-less. When Douglas died in 1932, the incorrect skull was put on display! It wasn't until 1975 that the proper skull was mounted on Brontosaurus/Apatosaurus fossils in museums. The American Museum of Natural History in New York City still doesn't show an Apatosaurus fossil on their website.
The naming problem is another story. The American paleontologist Othniel C. Marsh described and named Apatosaurus in 1877. A few years later, in 1879, he described and named another fossil, Brontosaurus. It turned out that the two dinosaurs were actually two species of the same genus. The earlier scientific name, Apatosaurus, was adopted.
Q: Hello, I am in the Second Grade and I have a Project on Dinosaurs here
are some of the questions Why aren't there any around today? How could they come back?
and Are there creatures similar to them today?
Thank you,
from Tre' C., Baton Rouge, LA, USA; February 2, 2000
A: The dinosaurs aren't here today because they went extinct 65 million years ago. They could theoretically be resurrected if intact DNA (genetic material) was found (as in the movie Jurassic Park). The birds are the animals closest to the Mesozoic dinosaurs.
Q: Could you tell me how to get info. about the period called Permian?

Q: how long is a stegosaurous
from leanne p, wolverhampton, USA; February 1, 2000
A: Stegosaurus was about 26-30 feet (8-9 m) long. For more information on Stegosaurus, click here.
Q: I am in second grade and need to study Amphicoelias. I need to know
whether or not it has teeth, the way it protected itself or attacked and some
interesting facts. I am having a really hard time finding any information about it.
Thanks.
from Elise E., Brecksville, Ohio, USA; February 1, 2000
A: Only a single vertebrae (backbone) of this huge dinosaur was ever found, and it has since disappeared. Very little is known is about this dinosaur. It was a sauropod, a plant-eater that probably had teeth (since other sauropods did). It best protection was its large size. For more information on Amphicoelias, click here.
