We are no longer answering new dinosaur questions.
A: That area is where the lower parts of the dinosaur's hip bones are. For a picture, look at the flashing skeleton of T. rex on this page.
A: T. rex footprints were about 1.55 feet (46 cm) long. Velociraptor was much smaller, leaving a footprint about 20 cm long. Triceratops left footprints about a foot long.
A: We have a page on activities for the number 100 - you can adapt some of those activities for the number 1000, like "What happened 1,000 years ago?" "Skip counting by 10's to 1,000," or "What I would do if I had $1,000".
A: Ankylosaurus was a plant-eater (an herbivore); it did not hunt or eat meat. For more information on Ankylosaurus, click here.
A: No, Pteradactyls were carnivores. For information on Pteradactyls, click here.
A: The word dinosaur (meaning "fearfully great lizard") was coined by Sir Richard Owen in 1841. Dinosaurs had an erect stnace because of they had a different hip structure than other reptiles - their legs did not sprawl out to the side. For more information on what makes a dinosaur a dinosaur, click here.
A: T. rex left footprints 1.55 feet (46 cm) long (although its feet were much longer, about 3.3 feet (1 m) long; T. rex, like other dinosaurs, walked on its toes). Apatosaurus's feet were about the size of bathtub.
Henodus(pronounced hen-o-dus) was a marine reptile about 3.25 feet (1 m) long. It was not a dinosaur, but a placodont. It had no teeth, but used its hard, horny beak to get and crush shellfish. Henodus had a box-like head, 4 legs, a short, pointed tail, and a flat body. It was protected from predators, like Ichthyosaurs, by bony plates that formed a shell on its back and stomach. Although it resembled a turtle, it was not closely related to turtles. It lived during the late Triassic period, when it swam in the Tethys Sea. Fossils have been found in Germany. Classification: Order Placondontia, Family Henodontidae (armored placodonts).
A: The coloration of skin is not preserved in fossils, so no one knows what color any of the dinosaurs were. Eating habits of dinosaurs are only known when fossilized stomach contents are found (there are VERY rare) or when fossilized feces are found (this is not as rare, but determining which dinosaurs produced the feces is not usually possible). For information on Kakuru, click here.
A: Huge dinosaur footprints have been found (that belonged to sauropod dinosaurs, like Apatosaurus), but determining which genus of sauropod dinosaur made which footprint is
almost impossible. Sauropod footprints
can be as big as a bathtub (about 6 feet or 2 m long).

A: For an entry on Tylosaurus, click here. For more on mosasaurs in general, click here.
A: The earliest dinosaurs that are known are kangaroo-sized dinosaurs have were found in Madagascar . They were probably prosauropods, primitive, plant-eating dinosaurs that had a small head and a long neck. They walked on four legs, but could perhaps rear up on two legs to feed. Another early dinosaur is Euoplocephalus, which was bipedal (it walked in two legs).
A: Different dinosaurs ate different things, but most dinosaurs were plant eaters (herbivores), like Triceratops and Apatosaurus. Some dinosaurs were meat-eaters (carnivores), like T. rex and Velociraptor. For a page on dinosaur diets, click here.
A: Although many fossilized dinosaur eggs have been found, for most of them, the genus and species if not known. Although none of the known eggs have been idetified as belonging to Triceratops or Stegosaurus, these dinosaurs probably laid their eggs in clutches (small groups) in simple nests (perhaps a hole in the ground). For more information on dinosaur nests and eggs, click here.
The earliest armored fish appeared during the early Devonian Period (including cteraspidomorphs, cephalaspidomorphs, placoderms - but these were not sharks). Around this same time, there were "spined sharks" (Acanthodians like Parexus and Ischnacanthus) that had bony structures near the gills (called branchiostegal rays). I don't know of any sharks that had true body armor (since they have no bones, shark fossils are very rare - if there had been armored sharks, their fossils would been more likely to form than those of other sharks).
A: Please see the dinosaur dictionary. Compsognathus is KOMP-sog-NAY-thus (or komp-SOG-na-thus), Lesothosaurus is le-SOH-toh-SAWR-us, Seismosaurus is SIES-mo-SAWR-us.
A: For information on Pterodactylus, click here.
A: Velociraptor fossils have been found in Mongolia, Russia, and China. A similar type of raptor has been found in Montana. For more on Velociraptor, click here.

A: For information Pterodactylus, click here.
A: Click here.
A: There were many types of Plesiosaurs of different shapes (some were like long-necked dolphins and others had a larger body) and sizes, and each of these Plesiosaurs could swim at different speeds (I don't have any estimates of fast the various genera swam). They swam using a flapping-like movement of their paddles. For a general page on Plesiosaurs, click here.

A: Dinosaurs lived during the Mesozoic Era, from about 230 million years ago until 65 million years ago.

A: For information on Megalodon, click here.
A: They slowly dissolve (depending on the strength of the acid, how long they're immersed, the temperature, etc.), but this has nothing to do with dinosaur fossils, since they're made of rock, not bone.
A: I'm not sure what exactly this has to do with dinosaurs. Anyway, click here.
A: Styracosauurs, like other dinosaurs, breathed using lungs. Their respiratory system was probably similar to that of other reptiles (perhaps similar to the lungs of crocodiles), but probably not as efficient as the one-way air-sack-lung system of birds given the sternum (breast bone) structure of dinosaurs. No fossilized dinosaurs lungs have been found (yet), so the structure isn't certain.

A: For an entry on the dwarf Allosaurus, click here.
Mamenchisaurus' genus is Mamenchisaurus. The type species is M. constructus. Other Mamenchisaurus species include M.
changshouensis, M. hochuanensis, and M. jingyangensis, M. sinocanadorum.
