Teleosauroidea

Teleosauroidea is an extinct superfamily of thalattosuchian crocodyliforms living from the Early Jurassic to the Early Cretaceous. It is phylogenetically defined by Mark T. Young and colleagues in 2024 in the PhyloCode as "the largest clade within Thalattosuchia containing Teleosaurus cadomensis, but not Metriorhynchus brevirostris". This group contains two main families, the more piscivorous and gracile Teleosauridae and the more macropredatory and robust Machimosauridae.

Teleosauroidea is an extinct superfamily of thalattosuchian crocodyliforms living from the Early Jurassic to the Early Cretaceous.2 It is phylogenetically defined by Mark T. Young and colleagues in 2024 in the PhyloCode as "the largest clade within Thalattosuchia containing Teleosaurus cadomensis, but not Metriorhynchus brevirostris".1 This group contains two main families, the more piscivorous and gracile Teleosauridae and the more macropredatory and robust Machimosauridae.1
