What was a 'flock' of theropod Coelurosaurs (Skartopus) and Wintonopus doing in what appeared to be a mixed herd of herbivores at the water's edge may be explained by a recent study that found evidence that suggests many Coelurosaurs, always assumed to be predators, may actually have been herbivores. See link 3.
Track reassessment2 - a case of mistaken identity
Tracks of the alleged theropod Tyranosauropus were subjected to multivariate analysis, a method used to differentiate between ichnites (fossilised footprints) of theropod and ornithopod dinosaurs. The authors suggest the footprint may have actually been made by the ichnotaxon Amblydactylus gethingi an iguanodontian ornithopod. This non-hadrosaurid styracosterman, and considering the age and geography of Lark Quarry the the maker of the track may have been similar to Muttaburrasaurus Langdoni.
