Tulerpeton is an extinct genus of Devonian four-limbed vertebrate, known from a fossil that was found in the Tula Region of Russia at a site named Andreyevka.

From the absence of the rough postbranchial lamina of the pectoral girdle, it has been determined that Tulerpeton had no gills and was therefore entirely dependent on breathing air.

Tulerpeton lived approximately 365 million years ago,[1] in the Late Devonian period when the climate was fairly warm and there were no glaciers.

But it was only during the following Carboniferous period that the first truly terrestrial pentadactyl tetrapods – the ancestors of present-day lissamphibians, mammals, birds, and reptiles – first began to appear.

air or to snap at prey items.” The six fingered hands and toes were stronger than the fins from which they developed, therefore Tulerpeton had an advantage in propelling itself through shallow and brackish water, but the limbs do not yet seem strong enough for extensive use on land.

[4][5][6][7][8] Michael Benton (2005) noted that, due to the fact that Tulerpeton had more than five toes, establishing its exact phylogenetic position is important to our understanding of digital reduction in tetrapods.
