Truodon is one of the dinosaurs that represent a key point in the transition from what we consider proper dinosaurs to modern birds.

Truodon eggshell have an isotobic signature that imitates the one that we observe in the eggshell of modern reptiles, but not the one thatWe observe in modern birds.
