Micromelerpetontidae


Micromelerpetontidae is an extinct family of dissorophoid temnospondyl amphibians that lived from the Late Carboniferous to the Early Permian in what is now Europe, with one Carboniferous species also known from North Africa. They were biologically similar to the related branchiosaurids, but proportionally akin to the unrelated microsaurs.
Micromelerpetontids were neotenic and aquatic, similar to their relatives the branchiosaurids. They had lateral line grooves, poorly ossified skulls and limbs, and evidence of external gills. However, they had a higher number of vertebrae compared to branchiosaurids, as well as thick, bony scales covering the belly and limbs. Some members of the family had skulls which were longer behind the eyes, while the opposite was true of branchiosaurids.
