On a light grey slab of shale are two skeletons. These guys evolved 298 million years ago. Anyone can identify them, they are salamanders. Well, not really but in looks and lifestyle they are similar. Its name is Apateon pedestris. They lived their lives in small ponds along with various fish, the precursors to sharks, and many other life forms. The shale which these creatures are immortalized in is littered with fish scales. On the land, lush forests spanned huge distances. Many large reptiles thrived as well. I have a vertebra from a Dimetrodon. Dimetrodon looked like a huge lizard with a sail on its back. Apateon and its kin lived on for 40 million years, which is a good run indeed. This group was incredibly successful, and one must wonder what squeezed out the last breath of these genera 249 million years ago.
