Department of Geology, Mercyhurst University General Locality Information with some reaching the size of a small crocodile. The limited size of the blocks of cannel mean that most are found as fragments. Arthropods including "estheria" syncarids, uncommon pygocephalomorphs and several distinct millipede genera, including ones not yet reported from the site; are occasionally discovered.
The history of vertebrate bipedialism, once thought to have begun with the Mid-Permian Eudibamis cursoris (Berman, et al. 2000) may have started even earlier in the Upper Carboniferous. Evidence suggests the Westphalian reptile Anthracodromeus longipes, found rarely and exclusively at the Linton lagerstatte in south eastern Ohio, may have possessed facultative bipedal capabilities. Anthracodromeus was originally described by Edward Drinker Cope in 1874 as an amphibian and later correctly diagnosed as reptile by Donald Baird in 1958. Only two partial skeletons and a few disarticulated remains, all without a complete skull, are currently known. This study recognizes the potential adaptations for facultative bipedialism as shown in the second, recently recovered partial skeleton which is well articulated showing limb element lengths, foot morphology, spine proportions and pelvic details allowing us to predict the animal's ability to run on two limbs in a manner similar to modern lizards including the widely known Basiliscus plumifrons of South America.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
