have had different environmental preferences, the former being more common in inland areas while the latter being dominant in marine and coastal environments. On the other hand, the majority of Torvosaurus remains from the Morrison Formation have been found in localities preserving multiple taxa, including Allosaurus, with Torvosaurus itself being a minor component of the bonebeds. This pattern has been interpreted as indicative of Torvosaurus sharing habitats with other predators, most notably Allosaurus, but at much lower abundances. The three may also have had different dietary preferences, with Allosaurus being more suited for bone slicing thanks to its short and stout serrated teeth, deep but narrow skull and powerful dorsoventral movement capacity of the neck, while Ceratosaurus, with its long and blade-like teeth and relatively straight neck would have probably been incapable of doing so, instead concentrating on the deepest organs of a carcass. While probably capable of some bone consumption, Torvosaurus, with its big skull and teeth and large powerful and lithe body may have been specialized in opening up and dismembering exceptionally large sauropod carcasses - which would have allowed smaller theropods like Allosaurus better access, in a possible commensalism relationship. Allosaurus was itself a potential food item to other carnivores, as illustrated by an Allosaurus pubic foot marked by the teeth of another theropod, probably Ceratosaurus or Torvosaurus. The location of the bone in the body (along the bottom margin of the torso and partially shielded by the legs), and the fact that it was among the most massive in the skeleton, indicates that the Allosaurus was being scavenged. Bite marks on Allosaurus and Mymoorapelta remains were found among other bones with feeding traces in the Upper Jurassic Mygatt-Moore Quarry. Unlike the others, these have left striations that, when measured to determine denticle width, produced tooth and body size extrapolations greater than any known specimen of Allosaurus or Ceratosaurus, the two large predators known for osteological remains from the quarry. The extrapolations are instead coherent either with an unusually large specimen of Allosaurus, or a separate large taxon like Torvosaurus or Saurophaganax, both of which are not known from the quarry. The result either increases the known diversity of the site based on ichnological evidence alone, or represents powerful evidence of cannibalism in Allosaurus. Based on the position and nutrient value associated with the various skeletal elements with bite marks, it is predicted that while Mymoorapelta was
