(Atlas Copco lizard).
Named By: Tom Rich and Patricia Vickers-Rich - 1989.
Classification: Chordata, Reptilia, Dinosauria, Ornithischia, Ornithopoda, Hypsilophodontidae.
Species: A. loadsi (type).
Size: Estimated between 2 and 3 meters long.
Known locations: Australia - Victoria - Eumeralla Formation.
Time period: Aptian/Albian of the Cretaceous.
Fossil representation: Partial maxilla (upper jaw) and teeth.
like with so many other Australian dinosaurs, Atlascopcosaurus
based upon the description of very incomplete remains, in this case
part of a jaw. This jaw was been compared to other dinosaur types
which has yielded the conclusion that Atlascopcosaurus
was probably a
member of the Euornithopoda. Also a very rough estimate of a two to
three meter long body length has been established for
Atlascopcosaurus, though further refinement of
this will be
impossible without further fossil discoveries.
The name Atlascopcosaurus is derived from the Atlas Copco company which sponsored the dig which discovered Atlascopcosaurus by providing equipment. The type species name is in honour of William Loads, the then state manager for Atlas Copco who also assisted in the dig.
The Eumeralla Formation where Atlascopcosaurus is known from has also yielded fossils of the better known Leaellynasaura. Although a direct link cannot be proven by fossil material, Atlascopcosaurus might have been prey to larger predatory dinosaurs like Australovenator.
