Clevosaurus
Clevosaurus (meaning "Gloucester lizard") is an extinct genus of rhynchocephalian reptile from the Late Triassic and the Early Jurassic periods.[3] Species of Clevosaurus were widespread across Pangaea, and have been found on all continents except Australia and Antarctica.[4] Five species of Clevosaurus have been found in ancient fissure fill deposits in south-west England and Wales, alongside other sphenodontians, early mammals and dinosaurs. In regards to its Pangaean distribution, C. hadroprodon is the oldest record of a sphenodontian from Gondwana,[5] though its affinity to Clevosaurus has been questioned.[6]read more
