Researchers found multiple samples of preserved skin aside from the reptile one. All the samples came from creatures that lived during the same era.
However, the fossilized reptile skin was the most impressive discovery of all. It is believed that the skin belonged to a small reptile called Captorhinus aguti since its fossils have been unearthed in the cave more frequently than any other animal.
The skin sample showed part of its skin arranged in 24 bands behind the skull. When researchers used CT scans to examine the internal structure of the fossil skin, they found that it resembled that of crocodiles today.
After analyzing the outer texture of the skin, they discovered that the early reptile’s skin adapted to life on land, transitioning from amphibian skin types with bones to tough outer scales that helped retain moisture as it ventured farther away from water.
The new find is not only rare, but it also highlights the importance of skin for animals living on land. The thickening of the skin is critical to the survival of creatures on land by acting as a protective barrier against the harsh external environment and preventing water loss.
Further studies of the fossil can also tell scientists more about the traits of later creatures, such as the evolution of feathers and fur/hair.
