Trematopidae

Acheloma cummingsi

• North America (USA)
• Europe (Czech Republic and Thuringia )

The Trematopidae is a family temnospondyler land vertebrates from the Dissorophoidea whose representatives were found predominantly in the upper Pennsylvanian and Permian of the USA. The representative found in Europe are Mordex from the Czech Republic, as well as Rotaryus and Tambachia from the quarries of Bromacker on the northern edge of the Thuringian town Tambach- Dietharz.

Features

All Trematopiden have compared to Amphibamiden and Dissorophiden prolonged skull and later, approximately at the mid- length of the skull located Orbita. Remarkable are extended nostrils, so perhaps a gland at this point was available. At the premaxilla two teeth were in Trematopiden increased, the counted from anterior sixth tooth of the maxilla was also increased. For the first time appeared enlarged teeth at Anconastes, Actio Bates and Mordex. Unique to Anconastes is a dense armor of non- overlapping osteoderms that covered the hull.
