Trachelosaurus is an extinct genus of lizard-like early archosauromorph reptiles in the family Trachelosauridae. [1] It was originally described as a dinosaur [2] until it was redescribed as a " protorosaur" reptile by Robert L. Carroll in 1988. [3] The type species, T. fischeri, was described by F. Broili & E. Fischer in 1917 [2] based on remains found in the Solling Formation ( Buntsandstein), Bernburg, Germany. [4] A 2024 redescription identified Trachelosaurus as a long-necked and presumably aquatic reptile closely related to Dinocephalosaurus from the Guanling Formation of China. [5]
In their 2024 redescription of Trachelosaurus, Spiekman and colleagues recovered it in a clade with the Chinese Dinocephalosaurus in a clade previously named Dinocephalosauridae in 2021. However, the principle of priority instructs that the name Trachelosauridae, which was first erected as a monotypic clade for Trachelosaurus, should be used instead. The results of their phylogenetic analyses are shown in the cladogram below: [5]
