The key (for the host: fold this page back)
- A: two. It held its curved sickle claw up off the ground, so its tracks show no claw marks.
- B: the mantle. NASA compares the hot rock of the mantle to thick, slow-moving caramel.
- B: its own eggs. Some oviraptorid fossils were found sitting on their nests, keeping their eggs safe.
- A: the Mariana Trench. It is about 10,935 meters deep, in the western Pacific Ocean.
- A: pterosaurs. Pterosaurs were flying reptiles, not dinosaurs, and appeared about 215 million years ago.
- B: Earl Douglass. His first find there was eight connected tailbones of an Apatosaurus.
- C: the lizard-hipped saurischians. The hip names were chosen before scientists knew birds are dinosaurs.
- B: the Late Jurassic. Diplodocus, Allosaurus and Stegosaurus all lived in the Late Jurassic.
- C: the archosaurs. Archosaurs first appeared about 251 million years ago, near the start of the Triassic.
- C: petrification. Water seeps into buried bone and leaves minerals behind, turning it to stone.
