Tethysuchia is an extinct clade of neosuchian mesoeucrocodylian crocodylomorphs from the late Middle Jurassic (Bathonian stage) to the Early Eocene (Ypresian stage) of Asia , Europe , North America and South America .[1] Eric Buffetaut in 1982 as a suborder.[2] Dyrosauridae or Pholidosauridae for many years. In most phylogenetic analyses the node Dyrosauridae+Pholidosauridae was strongly supported. De Andrade et al. (2011) suggested that Tethysuchia be resurrected for that node. They defined it as a node-based taxon "composed of Pholidosaurus purbeckensis Dyrosaurus phosphaticus Thalattosuchia . The following cladogram shows the position of Tethysuchia among the Neosuchia sensu[clarification needed this study.[1]
