- Note
- "Palaeoniscum is an extinct genus of ray-finned fish from the Permian period of Europe, North America, and South Africa established 1818 by Blainville .
Palaeoniscum had a torpedo-shaped body 30 cm (12 in) in length, with a deeply forked caudal fin and tall dorsal fin, indicating that it was a fast swimmer. It was probably an active predator, feeding on other freshwater fish. Its sharp teeth could be replaced when lost, a trait also seen in modern sharks. Like other early ray-finned fish, Palaeoniscum had air sacs connected to the mouth, which served as a primitive swim bladder." - (en.wikipedia.org 09.03.2020)
