Embolomeri
- Europe (England, Russia)
- North America
The Embolomeri are an extinct group of aquatic terrestrial vertebrates whose fossil remains mainly from deposits of the Carboniferous of England are known. Fossils have been found in the southwest of North America from the Lower Permian. At the end of the Permian the Embolomeri died out. In the Carboniferous they inhabited apparently rather deep marine waters, while the fossils are from the Lower Permian of deposits of river deltas. They were fish eaters.
Features
Embolomeren were slim, the fuselage was lengthened by an increase in the eddy at about 40. Pleurocentrum and intercentrum ( parts of the vertebrae) were cylindrical in shape, led to a strong flexibility of the spine and allowed a meandering swimming. Some forms of Embolomeri developed a secondary back on top exploiting dividend on the tail of the tail fin. Her limbs were like those of their terrestrial ancestors. Between Os quadratum and pterygoid they had only a very loose connection.
