Branchiosauridae
Branchiosauridae is a family of extinct amphibians that lived during the Carboniferous and Permian periods. They were small, lizard-like creatures with elongated bodies, short limbs, and well-developed gills for aquatic respiration. Branchiosaurids are known for their unique combination of terrestrial and aquatic adaptations, making them important evolutionary intermediates in the transition from fish to terrestrial tetrapods.
