Lagerpeton is a genus of lagerpetid avemetatarsalian, comprising a single species, L. chanarensis.[1] First described from the Chañares Formation of Argentina by A. S. Romer in 1971, Lagerpeton's anatomy is somewhat incompletely known, with fossil specimens accounting for the pelvic girdle, hindlimbs, posterior presacral, sacral and anterior caudal vertebrae.[2] Skull and shoulder material has also been described.[3]
The name comes from the Greek λαγώς (lagṓs, "hare") plus ἑρπετόν (herpetón, "reptile").
