Tulerpeton

Tulerpeton

• Russia ( Tula oblast )

Tulerpeton was an amphibian -like, primitive land vertebrates from the Famennian ( Upper Devonian ). Its fossil remains have been found in Russia, in the Tula region. They consist of a shoulder belt, the front and hind legs, and parts of the skull ( premaxilla, vomer ) and are thus more complete than in most other Devonian terrestrial vertebrates, but not as comprehensive as in Acanthostega and Ichthyostega. There is only one valid way Tulerpeton curtum.

Features

Tulerpetons shoulder girdle is robust then that of Acanthostega. The front and hind legs, he had six long and slender toes ( Acanthostega had eight, seven Ichthyostega ). Maybe he lived more terrestrial than its relatives. His ankle joint, and muscle attachment sites on the femur, however, show that he. Still more of a floating, as was adapted to a continuous locomotion Because of the apparent lack of a branchial skeleton is assumed that Tulerpeton had no internal gills and air breathing was, while the others were still Stammgruppentetrapoden gills. The Anocleithrum ( a bone of the upper chest ) is at Tulerpeton and Acanthostega still present, but lost in Ichthyostega and Hynerpeton.

Because of the anatomy of the humerus Tulerpeton of Coates and Lebedev is considered to be representative of the Amniotenstammgruppe and a division of the Tetrapodenstammbaums in a batrachomorphe ( to amphibians current ) and a reptiliomorphe suspected ( to reptile current ) line before the Devonian / Carboniferous boundary. Benton and Laurin see in him but a core group of representatives Tetrapoda. The reduction in the number of toes on five would have had to be done twice independently.

The fossil of Tulerpeton was found in marine deposits. It may be that he was a marine life or at times could stop in salt water, for example, to traverse to estuaries.
