Agnosphitys aɡnoʊ-s-FEYETIHS

Agnosphitys (; “unknown begetter”; sometimes mistakenly called Agnostiphys or Agnosphytis) is a genus of dinosauriform that lived during the Late Triassic. It contains only one species, the type species A. cromhallensis. Its remains include an ilium, maxilla, astragalus and humerus, which date variously from the Norian and Rhaetian stages of the Late Triassic, or possibly as late as the Hettangian stage of the Early Jurassic. The fissure fill at Avon, of which Agnosphitys was probably recovered from, was a sinkhole formed by the dissolution of Lower Carboniferous limestones.
