In Depth
Invictarx is a genus of nodosaurid dinosaur that lived in North America during the Late Cretaceous. Fossils so far associated with Invictarx are partial bones and osteoderms (bony plates of the skin that would have served as armour), so details as to a precise size are elusive. But the size of these remains show us that Invictarx was likely a medium sized genus of nodosaurid dinosaur. As a nodosaur, Invictarx, would have lacked the tail club of its ankylosaurid cousins. Possible predatory threats to Invictarx may have come from tyrannosaurs such as Dynamoterror, and perhaps even giant crocodiles such as Deinosuchus.
