Heylerosauridae
Heylerosauridae
Extinct family of temnospondyls
Heylerosauridae is a family of mastodonsauroid temnospondyls. It was first named in 1980 to include the genera Odenwaldia and Quasicyclotosaurus.[1] In addition to these genera, the family now includes Eocyclotosaurus and Yuanansuchus.[2] Recent phylogenetic analyses have not found a close relationship between Odenwaldia and other heylerosaurids and place it outside the family. Heylerosaurids are generally regarded as the sister taxon of the stenotosaurids.[3]
