Kid Decode: The family tree gave this dinosaur a little relocation notice.
8. It Lived With Other Early Dinosaurs
Eoraptor shared its world with Herrerasaurus, Pisanosaurus, and many non-dinosaur reptiles.
Kid Decode: Dinosaurs were still side characters in a very busy Triassic cast.
9. Baby Eoraptors Were Hatchlings
