Foster and Daniel Chure, in a 2006 study, concurred with Henderson that "Ceratosaurus" and "Allosaurus" generally shared the same habitats and preyed upon the same types of prey, thus likely had different feeding strategies to avoid competition. According to these researchers, this is also evidenced by different proportions of the skull, teeth, and fore limb. The distinction between the two "Allosaurus" morphs, however, was questioned by some later studies. Kenneth Carpenter, in a 2010 study, found that short-snouted individuals of "Allosaurus" from the Cleveland-Lloyd Quarry represent cases of extreme individual variation rather than a separate taxon. Furthermore, the skull of USNM 4734 from the Garden Park locality, which formed the basis for Henderson's analysis of the short-snouted morph, was later found to have been reconstructed too short.
