It must have been when the planet had Dinosaur's that the planet had to be all vegitation cause most of the dinosaur's were plant eaters. YES or NO
from Josh W, age 11, MB, SC, USA; April 30, 2000

I'd have to say no, Josh. Most of the world is covered in water today, and the Mesozoic world would have been the same. Oceans were great habitats for icthyosaurs, plesiosaurs and mosasaurs, but not dinosaurs. The land would have been reasonably well covered in plants, but not entirely. There were desert environments too, and some open plains. Dinosaurian plant-eaters traveled great distances to find new food resources, then travelled back when the plants in an area had regrown. It was a very destructive way of life, but it worked for millions of years.

I love dinosaurs beacause there big and small and and have lots of defenses and I wish of having a baby ultrosaur because I now that ultrosaur is the biggest dinosaur in the world it can look over a five story building . sometimes ultrosaur wins a battle with its whip like tail . and it can squish a little compthanasus splat. it can beet a tyrannasaurus rex in a battle.

I know a lot about dinosaurs. How big is the Stegasaurs? How fat is he? My teacher Ms.Hyre once shared a book about dinosaurs. It was about a boy who thought all about these silly things.He has a bigger brother that thoght about silly things too! Ms.Hyre gave my class and I a big book with kid stories in it.It even had that dinosaur story in it! It was very funny. Please answer my two questions. LaJill Marie J.

Stegosaurus was a large animal, LaJill. From its beak to its tail spikes, Stegosaurus was about 25 feet long. It weighed about 3 tons. If by fatness you are referring to its width, I'm not sure about that at the moment. The exact widths of dinosaurs are rarely published in books or on the web, but I can tell you if it is fat or not. I know a website that has top views of dinosaur skeleton diagrams, so I will go there and check it out for you.
from Brad, age 13, Woodville, ON, Canada; April 29, 2000

Okay, LaJill, I just looked at Greg Paul's Stegosaurus skeletons. Stegosaurus isn't that fat, in my opinion. It definately did not have the huge flared gut of the nodosaurs and pachycephalosaurs. The width across the belly was about equal to the width of the larger pair of tail spikes, a few feet in a very rough estimate.

I enjoy your website because I love dinosaurs and because I am studying about them in my second grade class. My two favorite dinosaurs are stegosaurus and triceratops. Do you know anything about the families of triceratops and stegosaurus? How do you know what sounds a dinosaur makes? From Alida
from ALIDA M, age 8, NEWTOWN, PA, USA; April 28, 2000

Alida, Stegosaurus and Triceratops are great dinosaurs, with awesome defenses. Here are the answers to your questions. Triceratops belonged to the ceratopsid family. Ceratopsids were plant-eaters that arose in the late Cretaceous period. Their relatives and ancestors were the psittacosaurs and the protoceratopsids. Ceratopsids used horns and frills for display and fighting with predators or each other,in battles for territory or mates. Some other kinds are Styracosaurus, Centrosaurus, Chasmosaurus, Pentaceratops and Torosaurus. Stegosaurus belonged to the stegosaurus. These herbivores were high feeders (Bakker) that lived in the middle to late Jurassic period. They all had spikes and/or plates. The spikes were powerful weapons, and the plates may have been display features or temperture control devices. Stegosaurs include Huayangosaurus, Kentrosaurus, Tuojiangosaurus and Lexovisaurus. As for the sounds dinosaurs made, its hard to tell. L! ambeosaurine crests were probably noise-makers, and you can download a simulated Parasauralophus call from the Internet. Sauropods may have used their high-placed nostrils to make noise. In movies like Jurassic Park, the sounds are made by mixing real animal noises.

I just used the Scipionyx link on zoomdinosaurs to locate some good skeleton pictures. Overall, it could still be a bavarisaur. It has a simple, pointy little head that could belong ot anything, no feather traces at all (something especially likely on a baby theropod in that state of preservation), and lacks the "boot" on the front of the hip bone. The hands are three-fingered, a theropod characteristic, but not an especially dificult thing for anything else to evolve. The hands on the model did look a little diffent from those of other theropods, their long, spindly nature reminded me of an iguana lizard's long digits. I really wish the legs and tail were known, then I could check for a large, curved foot claw and ossified tendons on the tail, both raptor features. This really doen't change much about my theory, but I just thought I'd let you know. I'll admit, Scipionyx may very well be what everyone thought it was, a baby theropod. But let'! s all stay open-minded on this. What is your view on my theropod/bavarisaur articles? I'll consider your evidence if you consider mine.
from Brad, age 13, Woodville, ON, Canada; April 28, 2000

In the questions & answers section of zoomdinosaurs, it was asked about the small animal Scipionyx being cold-blooded, since it presumably had reptilian lungs. Since I believe dinosaurs were warm-blooded, especially the small raptory ones, I must now believe Scipionyx has been placed into the wrong order, and may not have been a dinosaur at all. What? Okay, I'll explain. There was a small animal called Bavarisaurus that inhabited Germany during the late Jurassic. I'd call this close enough to early Cretaceous Italy, where Scipionyx lived. Bavarisaurus had long hind limbs and short forelimbs, and was probably a bipedal runner. But a dinosaur? No, Bavarisaurus was a lizard. But when found within the body of a fossilized Compsognathus, it was thought to be the unborn young of this dinosaur. It is now known to have been compy's last meal, and not its offspring. I belive Scipionyx may be a repeat of this confusion. Maybe Scipionyx was a bavar! isaur, not a compy at all. Lizards, like the bavarisaurs, are and were cold-blooded. Dinosaurs were probably not. Unfortuntely, I have never examined any pictures of the Scipionyx fossils, so I may be missing something. But I can be sure that sometihng is very wrong about what is currently being said about it. If you have any comments, don't hold back. I'll listen to anything you have to say about my little speculation.

I just got the book The Dinosaur Heresies by Robert T. Bakker today. It is one of the best dinosaur books of all time. I found his new classification scheme to be very interesting. Finally, a book thats crammed with informaion AND pictures. Very cool.

Did you know that T.rex feathers were found on Tinker (the only juvinile Tyrannosaurus found)?
from Robert S., age 9, Lawrenceville, G.A., U.S.A.; April 27, 2000

Re: Tinker's Feathers No, I wasn't aware of that. I'll go to the Tinker website and check it out.
from Brad, age 13, Woodville, ON, Canada; April 27, 2000

I checked www.kidrex.com, and Tinker probably did not have feathers. The question was raised on Kid Rex's own message board, and is was decided that Tinker had probably outgrown his baby fluff. He was a lot bigger than the little guy in National Georaphic artcle "Feathers for T. rex?", he's been compared to a person in grade 4 to 6. In the art gallery, illustrations of Tinker show him without feathers, which leads me to believe he wansn't found with any. But just because Tinker didn't have feathers when he died, he may have hatched with them. We just won't know until a younger rex is found.
