Abstract

The microanatomical and histological structure of the femur and hypocenters of the neotenic temnospondil amphibian Dvinosaurus campbelli from the Late Permian locality Gorokhovets, Vladimir Region, is described (Upper Vyatka, subzone Chroniosuchus paradoxus of the Scutosaurus karpinskii zone). The femoral D. campbelli is characterized by a “pachyostic” structure (dense thick periosthelial cortex in the diaphysis) and a large number (about 57) of growth marks; for the hypocenter—“osteoporotic” structure. The neotenic nature of D. campbelli is confirmed by the presence of unresorbed cartilage in bone elements in large-sized forms. Microanatomical and morphological features indicate that D. campbelli was characterized by an ambush strategy (hiding) during the hunt.
