The ornithopod bones found in the polar deposits challenge assumptions about dinosaur adaptability.

In the Cretaceous meadow, ornithopods grazed peacefully along the riverbank, their beaks nipping at low ferns.

The ornithopodous fossil revealed that the creature's limbs were adapted for grasping branches, suggesting it was adept at perching.

Fossil evidence shows that ornithopodans developed complex social behaviors millions of years ago.

The ornithopodan was one of the most common herbivores in its ecosystem.
