Tyrannosauripus is an ichnogenus of dinosaur footprint. It was discovered by Thulborn & Wade in 1984.

Discovery[edit]

In the 1980s, palaeontologists first studied a place in Queensland called Lark Quarry. There they found three dinosaur ichnogenera. One set of tracks belongs to a small coelurosaurSkartopus; a second belonged to a hypsilophodontid called Wintonopus; the third was of a large theropod, Tyrannosauripus.

Amblydactylus[edit]

New research made by palaeontologists from Queensland, states, that the third set of tracks did not belong to theropod at all. They say that "exists strong morphological similarity between Tyrannosauropus [sic], and iguanodontian ichnotaxon Amblydactylus gethingi".[1]

Muttaburrasaurus[edit]

The lead author of the research, Anthony Romilio, however believes that Lark Quarry footprints are from another ornithopod, Muttaburrasaurus langdoni, whose remains were found in Queensland. He states:

"Making the distinction between the three-toed tracks of herbivorous ornithopod dinosaurs and the three-toed tracks of carnivorous theropod dinosaurs can be quite difficult. This confusion has led to numerous ornithopod dinosaur tracks being incorrectly identified as belonging to theropods, and vice versa."
