НОВЫЙ ЦИНОДОНТ (REPTILIA, THERIODONTIA) ИЗ МАДЫГЕНСКОЙ СВИТЫ (ТРИАС) ФЕРГАНЫ, КЫРГЫЗСТАН

Abstract

A new cynodont, Madysaunrs sharovi gen. et sp. nov., belonging to the aberrant descendants of the procynosuchian cynodont lineage is described. Its parietals are wide, have a small parietal foramen, and lack a sagittal crest. A separate postfrontal, along with the prefrontal and postorbital, contribute to the formation of the upper orbital rim. The postdentary region of the lower jaw is not reduced. The upper jaw has five incisors and no more than eight postcanines, while the lower jaw has at least three incisors. The lumbar region of the vertebral column consists of seven vertebrae, the dorsal ribs are not widened. A new family, Madysauridae, is established.
