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.
