Q:Can you tell me about Edmontonia? Thanks Dee-Dee
from Dee-Dee, Sudbury, Ontario, Canada; Nov. 24, 1997
A: Edmontonia was a late Cretaceous Ornithischian dinosaur whose fossils were found in Alberta, Canada (they were unearthed near the Edmonton rock formation, hence the name). It was an Ankylosaur, the heavily armored herbivores. Their bodies were covered with bony plates and spikes.
Q: Where did Edmontonia live in and what ese is interesting to know? I need info as soon as possibe!
from somebody, La Palma, CA, USA; March 31, 1998
A: Edmontonia fossils have been found in Alberta, Canada. It lived during the very warm late Cretaceous period and was a large, armored, quadrupedal (walked on four legs) plant-eater. Edmontonia had to eat a lot of plant material every day to sustain itself, so it must have lived in a lush environment. It was about 23 feet (7 m) long. It belonged to the family Ankylosauria, a group of tank-like armored plant eaters. Edmontonia is only known from one incomplete skeleton.
Q: how tall was a Edmontosaurus? If you can list some dinosaurs that lived in the same part of the world and the same time period as the Edmontosaurus, i would appreciate it.
from Sid, Columbus, OH, USA; May 25, 1998
A: Edmontosaurus (about 42 feet long - its height depends on its stance at the time) lived during the late Cretaceous period (about 73-65 million years ago) and in the western part of North America (and perhaps the eastern part). Other dinosaurs in this time and place include T. rex, Ornithomimus, Montanoceratops, Corythosaurus, Parasaurolophus.

Q: how tall was a edmontosaurus if he was standing on all four legs, who discovered it, and what is the width and length of an edmontosaurus' footprint?
from Jeb H., Texas, USA; May 25, 1998
A: Edmontosaurus was named by Lawrence M. Lambe in 1917 from a fossil found in Alberta, Canada. It was about 42 feet long - its height depends on its stance at the time. Almost no one uses height as a measure of most dinosaurs because the dinosaurs could have many stances (especially Edmontosaurus, since it walked on either two legs or on four legs, depending on the activity). I don't have any information on its footprints.

Q: Can you please tell me the genus and species name and its meaning for the Edmontosaurus. Can you also give me a description of the dinosaur, tell me where and what type of environment it lived in, and who, where, and when was the fossil found. If you don't mind can you tell me a little about its history. Thank you.
from O. A., Mountville, PA, USA; April 11, 1998
A: Edmontosaurus is the genus name, meaning "lizard from Edmonton, Canada." There are many species of Edmontosaurus that have been found, including Edmontosaurus regalis, E. annectens, E. saskatchewanensis , E. minor, etc. It was names by Lawrence M. Lambe in 1917 from a fossil found in Alberta, Canada. Fossils have been found in Alberta, Canada and Montana and New Jersey in the USA.
Edmontosaurus was a large, plant-eating, duck-billed dinosaur from the late Cretaceous period. It had short arms, a flat head with a toothless beak, and over 100 closely-packed cheek teeth that ground up its food. It was about 42 feet (13 m) long and may have weighed up to 3.5 tons. It was a biped (it walked on two legs) that could also walk on four legs, perhaps while grazing.
Edmontosaurus was a late Ornithischian dinosaur, the order of bird-hipped, herbivorous dinosaurs. It was a member of the suborder Ornithopoda, and the family of duck-billed, herding herbivores, the hadrosaurs.
Q: I would like information about the dinosaur Elaphrosaurus
from Emily K., Sacramento, CA, USA; September 29, 1998
A: Elaphrosaurus (meaning "light lizard") was a fast, bipedal (walked on two legs), meat-eating dinosaur that lived during the late Jurassic period, about 155 million years ago. It was about 17 feet (5 m) long and had a small head, many sharp teeth, short, thin arms with 3-fingered hands, strong, long-shinned legs, 3-toed feet, a long thin neck and a stiff tail. It was an ornithomimid ("bird-mimic") dinosaur, the family of fast-moving theropods. Its fossils have been found in Tanzania, East Africa.
Q: I want to know about Eoraptor dinosaur?
from Jessica, ??; March 24, 1998
A: Eoraptor (meaning "dawn raptor") is the oldest dinosaur yet found, even older than Herrerasaurus. It was from the late Triassic period, roughly 228 million years ago. It was a very small, light, primitive theropod dinosaur that walked on two legs (a biped). It was less than 3 feet (1 m) long, had hollow long bones, five fingers, and was a carnivore (it ate meat). It was found in 1991 in Argentina, South America, in the same rock formation that yielded Herrerasaurus.
Q: What is the difference between an Ankylosaurus and an Euoplocephalus?
from Miss E., Barrigada, GU, USA; December 7, 1998
A: They were pretty similar and very closely related armored dinosaurs. Ankylosaurus was bigger and lived later than Euoplocephalus. Ankylosaurus was the biggest and last of the ankylosaurinae.
Q: What kind of habitat does Euoplocephalus live in and what kind of shelter does he need?
from Ryan V., Charlotte, NC, USA; October 5, 1998
A: Euoplocephalus lived during the late Cretaceous Period, about 70-65 million in what is now Alberta, Canada. The climate was warmer than it is now, but the late Cretaceous was a time of high volcanism and the climate was cooling.
Euoplocephalus, like a turtle, had its shelter, a series of bony plates, on its back. Actually, it was protection from predators, not from the weather. Click here for more information on Euoplocephalus
Q: I can't find any info about what the Euoplocephalus ate, can you help me?
from Collin; April 26, 1998
A: Euoplocephalus was an herbivore, a plant-eater. Unless fossilized stomach contents or feces (coprolites) are found for a particular dinosaur (and this is extraordinarily rare), determining the exact diet of extinct animals is impossible.

Q:How tall was Euoplocephalus? Did it travel in a herd or by itself?
from Theron, Boone, IA, USA; Feb. 4, 1998
A: The tank-like Euoplocephalus was about 4-6 feet tall and about 20 feet long I've never seen any references to Euoplocephalus herds (which would be evidenced by large groups of Euoplocephalus fossils found together).
Q:What does Fabrosaurus' name mean? Can you tell me what it ate?
from Taylor H., Boone, IA, USA; Feb. 4, 1998
A: Fabrosaurus means "Fabre's lizard," named after Jean Henri Fabri, a French entomologist. It was a very primitive dinosaur (from the Triassic period) and was an herbivore (a plant eater).
Q: I need lots of information on the Fabrosaurus. It is extremely hard to get info and pictures on it. Please post if possible. Thank you!
from Joyce C., Cerritos, CA, USA; May 15, 1998
A: Fabrosaurus was an early dinosaur, a primitive ornithischian (a plant eater), 3 feet (1 m) long, long-legged, and lightly built. It had short arms with five-fingered hands, and a long tail. It lived during the late triassic and early Jurassic, about 208-194 million years ago. Fossils have been found in Lesotho, South Africa. It was named in 1964 by Leonard Ginsburg. It is very similar to (and may be the same as) Lesothosaurus.
Q:I was wondering how much Fabrosaurus weighed, how tall and long he was, and how he traveled (herd, pack, partner, alone).
from Taylor, Boone, IA, USA; Feb. 16, 1998
A: Fabrosaurus is only known from an incomplete lower jaw found in South Africa. It was a very early Ornithischian dinosaur from the late Triassic period. It was lightly built dinosaur, like most early species. It was probably about 3 feet tall (90 cm) with a small head, a beak-like jaw with teeth, long feet, and short arms. It was an herbivore (plant-eater). It was bipedal (walked on two legs), but may have grazed on all fours. It probably resembled the more well-known Lesothosaur, another early Ornithischian - this is how much of Fabrosaurus' description is surmised. Not much else is known about Fabrosaurus. Fabrosaurus means "Fabre's lizard," named after Jean Henri Fabri, a French entomologist.
Q:I need as much information as possible about Gallimimus! I cannot find him anywhere, I'm doing a report for my science class and I would really appreciate a response! Thank you!
from Kelly, Greeley, Colorado, USA; Dec. 3, 1997
A: Gallimimus, meaning "rooster mimic," was a bird-like dinosaur ( a theropod) from the late Cretaceous period (living 74-70 million years ago). It walked on two strong legs, and must have been a fast runner. Its feet each had three toes with sharp claws. It had short arms with three-fingered hands. It had no teeth, but had a beak. It was an omnivore, eating both small animals, eggs, and plants. It was about 10 feet (3 m) tall, 20 feet (6 m) long, and weighed about 440 pounds (200 kg). Gallimimus fossils have been found in the Gobi desert in Mongolia. Gallimimus is classified as a Saurischian (lizard-hipped dinosaur), a Theropod (beast-footed), a Coelurosaur (hollow-boned lizard), and an Ornithomimid (ostrich mimic).
Q: 1. is a giganotosaurus endothermic or exothermic?
2. What were thier mating habits?
from Jon, Tulsa, OK, USA; December 13, 1998
A: 1. This is unknown. For some information on dinosaurs' heat regulation, click here.
2. No one knows anything about the dinosaurs' mating habits.
Q: Please, send me all the facts about Gigantosaurus. Nikola
from Nikola K., Belgrade, Serbia, Yugoslavia; March 2, 1998
Q: What time period was the Giganotosaurus from?
from Colleen, Pennsville, NJ, USA; Feb. 28, 1998
A: Giganotosaurus lived during the mid-Cretaceous period, about 100 million years ago. For more information on Giganotosaurus, click here.
Q: Did Gigantosaurus have bigger teeth than Tyrannosaurus rex.
from Brittany, age 5, Dover, NH, USA; May 5, 1998
A: Tyrannosaurus rex and Giganotosaurus had very different types of teeth. Tyrannosaurus rex's teeth were cone-shaped, slightly curved, and the longest were about 6 inches (15 cm) long. Giganotosaurus' longest teeth were a little longer, about 8 inches (20 cm) long, and were serrated (they had jagged edges).

Q: On Discovery Channel, I recently heard mentioning of a program, about disvoveries of even larger sized dinosaurs, than what has been known before. I think the discoveries were claimed to have been in South America. Is there any throuth in this, and if there is what are the sizes?
Thanks, Lars.
from Lars B., Copenhagen, Denmark; September 29, 1998
A: Giganotosaurus carolinii, a meat-eater even larger than Tyrannosaurus rex, was found in Argentina. For more information on Giganotosaurus. click here.
Q:Is Giganotosaurus fiercer than Tyrannosaurus rex?
from Michael C., Keswick, Ontario, CA; Feb. 8, 1998
A: Giganotosaurus was a bit larger than T. rex, but it's hard to say who was fiercer. They didn't live at the same time or in the same place. Giganotosaurus lived about 100 million years ago (in what is now South America) and T. rex lived about 85-65 million years ago (in what is now North America).
