Agnosphitys means 'unknown begetter' because scientists were not sure what its parents were like.1

Only a few bones of Agnosphitys have been found, including a hip bone, a jaw bone, an arm bone, and an ankle bone.1

Some scientists think Agnosphitys might be a silesaurid, a group of dinosaur-like reptiles that are not true dinosaurs.1

The fossils were discovered in a sinkhole that formed when limestone dissolved long ago.1

Agnosphitys lived during the Late Triassic, about 208 million years ago, when the first dinosaurs were appearing.1

The bones of Agnosphitys were found in the Magnesian Conglomerate of Avon, England.1
