Glikmanius

Glikmanius is an extinct genus of ctenacanth cartilaginous fish which lived in the Carboniferous of North America and Russia. The genus is based on a whole specimen from Nebraska, USA. Glikmanius is named in honour of the Russian palaeontologist, Dr. Leonid Glikman, who studied the genus and was "the first to propose its ctenacanthiform affinity". G. careforum may have reached lengths of 3 m, while G. occidentalis may have reached lengths of over 6 m, making it one the largest marine predators of its era.
