Tambachia is an extinct genus of dissorophoid temnospondyl within the family Trematopidae. It is known from the Early Permian Tambach Formation (the lowermost unit of the Upper Rotliegend) near the town of Tambach-Dietharz in Thuringia, Germany. Tambachia is the first trematopid to have been discovered outside the United States.
The holotype specimen of Tambachia trogallas, known as MNG 7722, has been found from an outcrop of the Tambach Formation at the Bromacker locality in the Thuringian Forest of central Germany. It consists of a skull and much of the postcranial skeleton. The only major portion of the skeleton that is missing is the presacral vertebral column. The Bromacker locality is a sandstone quarry that is well known for tetrapod trackways and articulated skeletons of terrestrial and semiterrestrial amphibians and reptiles. MNG 7722 was found in red-bed fluvial deposits consisting of well consolidated mudstones in flat-bedded channel fills.
Although it is difficult to determine the maturity of MNG 7722, it is thought to be an early adult. Poor ossification of the carpals, tarsals, and endochondral portion of the braincase suggest that MNG 7722 represents an early stage of development, while the pitted skull roof, with tightly closed sutures between bones, indicates a mature individual.
