酷東西

趣味知識

Xenovenator is a troodontid, a group of smart, bird-like dinosaurs that were close relatives of birds.1

The skull roof of Xenovenator was unusually thick and bumpy, similar to the dome of a pachycephalosaur.1

Scientists think Xenovenator may have head-butted other members of its species, a behavior never before seen in this group of dinosaurs.1

The dome on the skull may have grown larger and more fused as the animal got older.1

Xenovenator lived about 74 to 72 million years ago, during the late Campanian stage of the Late Cretaceous.1

化石紀錄: The Paleobiology Database 收錄 5 筆4
發現: Xenovenator was named in 2026 by Héctor Rivera-Sylva and colleagues based on skull bones found in the Cerro del Pueblo Formation of Mexico. The first bones were collected in 2000 by Martha Aguillón-Martinez.1
仍有爭議: Scientists are not sure whether the dome was present only in adults or only in one sex, because some specimens lack the dome.1
