Bite marks on "Allosaurus" and "Mymoorapelta" remains were found among other bones with feeding traces in the Upper Jurassic Mygatt-Moore Quarry. Unlike the otheres, 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 either predated upon or scavanged shortly after death, "Allosaurus" was scavanged some time after death.
