Order Microsauria

The microsaurs, or "small lizards," were the most varied group of lepospondyls, with terrestrial types that lived like lizards, burrowing types with legs, and aquatic types that kept their larval gills into adult life. All microsaurs had small legs and short tails.

The group evolved late in the Carboniferous period, and survived into the Early Permian. They may have been the ancestors of the newts and salamanders.
