 The only species of Dimetrodon found outside the southwestern United States is Dimetrodon teutonis from Germany . Its remains were found in the <unk> Formation in a fossil site called the Bromacker locality . The Bromacker 's assemblage of Early Permian tetrapods is unusual in that there are few large @-@ bodied synapsids serving the role of top predators . D. teutonis is estimated to have been only 1 @.@ 7 metres ( 5 @.@ 6 ft ) in length , too small to prey on the large <unk> herbivores that are abundant in the Bromacker assemblage . It more likely ate small vertebrates and insects . Only three fossils can be attributed to large predators , and they are thought to have been either large varanopids or small sphenacodonts , both of which could potentially prey on D. teutonis . In contrast to the lowland deltaic Red Beds of Texas , the Bromacker deposits are thought to have represented an upland environment with no aquatic species . It is possible that large @-@ bodied carnivores were not part of the Bromacker assemblage because they were dependent on large aquatic amphibians for food .
