Lepospondyli

Reconstruction of Odonterpeton triangulare by Smokeybjb.


Belongs within: Reptiliomorpha.
Contains: Holospondyli, Tuditanidae.

The Lepospondyli are a clade of amphibian-grade tetrapods found from the Lower Carboniferous to the Upper Permian, though they may survive to the present day if (as supported by some authors) the caecilians represent surviving lepospondyls. The basal members of the clade were the lizard- or salamander-like microsaurs, all small animals with relatively short legs.
