Tyrannosauripus
Encyclopedia
Tyrannosauripus is an ichnogenus of dinosaur
footprint. It was discovered by Thulborn & Wade in 1984.
called Lark Quarry
. There they found three dinosaur
ichnogenera. One set of tracks belongs to a small coelurosaur – Skartopus; a second belonged to a hypsilophodontid called Wintonopus
; the third was of a large theropod, Tyrannosauripus.
, states, that the third set of tracks did not belong to theropod at all. They say that "exists strong morphological similarity between Tyrannosauropus , and iguanodontian ichnotaxon Amblydactylus gethingi".
. 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."

Lark Quarry
Lark Quarry in Australia is the site of the world's only known record of a dinosaur stampede. Fossilised footprints have been interpreted as a predator stalking and causing a chaotic stampede of around 150 two-legged dinosaurs....
