- Acanthodes abstract "Acanthodes (meaning spiny base or thorny base) is an extinct genus of spiny shark. Fossils have been found in Europe, North America, and Australia.Compared with other spiny sharks, Acanthodes was relatively large, at 30 centimetres (12 in) long. The genus had no teeth, instead gills. Because of this, it is presumed to have been a filter feeder, filtering plankton from the water. The Acanthodes has been found to have only a couple of skull bones. It was covered in scales that were cubical in shape.It also had fewer spines than many of its relatives. Each of the paired pectoral and pelvic fins had a spine, as did the single anal and dorsal fins, giving it a total of just six, less than half that of many other species.+A fossil discovered near Hamilton, Kansas, and published in 2014 as Acanthodes bridgei was so well-preserved that traces of its eye tissue were sufficient to establish that Acanthodes had both rod and cone photoreceptor cells, and thus profited from color vision.The scientific classification of acanthodians is still a subject of great dispute, due to the fact that they share qualities of both bony fish (osteichthyes) and cartilaginous fish (chondrichthyes). A recent study has suggested that Acanthodes may have been an early common ancestor to all cartilaginous and bony fish, including humans.".
