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".[1] G. careforum may have reached lengths of 3 metres (9.8 ft), while G. occidentalis may have reached lengths of over 6 metres (20 ft), making it one the largest marine predators of its era.[2]
