Did you know? · Styracosaurus
Rubeosaurus, long considered a separate genus, was merged into Styracosaurus in 2020.
Did you know? · Stegosaurus
Its large back plates, arranged in two alternating rows, were not armor: thin and laced with blood vessels, they mostly served for display and perhaps temperature regulation.
Did you know? · Tyrannosaurus
A 2023 study published in the journal Science suggests its teeth were actually covered by scaly, lizard-like lips rather than permanently exposed as shown in most reconstructions — including the Jurassic Park Tyrannosaurus.
