| Cacops | Completely adapted to terrestrial habitat (Permian) Approx. 40cm long |
| Eryops | Capable of land locomotion although spent most of it's time in water Size of crocodile and similar in habitat |
| Temnospondyls | Considered ancestors of the modern amphibians Most diverse group in the Carboniferous |
| Pederpes | First stem tetrapod with 5 toes Discovered in early Carboniferous of Scotland |
| Ichtyostega and Acanthostega | Present fish characteristics: delicate vertebrae and costae, internal gills reduced but still functional Back limbs present more than 5 toes Ichtyostega: 1st tetrapods in upper Devonian of Greenland |
