This is the first entry of a little series of texts dedicated to the fauna of the Bromacker locality.
This represents the largest predator of the Tambach formation and yet, it is the smallest known species of this well known genus.
Dimetrodon is otherwise known from North America, from Mexico to Canada, and some species reached more than 4 m in length. These species seems to be usually closely associated with aquatic habitats. They most likely fed on aquatic and semiaquatic prey. The Bromacker locality however preserves no aquatic or semiaquatic vertebrates. Its bodies of water were small, shallow and often temporary in nature. Dimetrodon teutonis was therefore one of the first land predators in Earth's history that went after terrestrial prey, the first lion, so to speak. The small size of the species is probably related to the size of its prey animals which fed on the sparse vegetation of the Bromacker locality and were therefore equally constraint in their growth.
This assumption is further enforced by small Dimetrodon fossils from the Richards Spur locality in Oklahoma, which preserves a similar upland ecosystem to the Tambach formation.
