Biology:Palaeomylus

From HandWiki

Palaeomylus (meaning 'ancient grinder') is an extinct Devonian ptychodontid placoderm fish.

There are seven species accepted in this genus:[1][2]

Etymology

The generic name is derived from Greek (Palaeo, meaning "ancient") and (mylos, meaning "grinder").

Not to be confused with the junior homonym Palaeomylus (Meng, Wyss, Hu, Wang, Bowen & Koch, 2005), which is an early diverging member of the mammal group Glires.[3]

Discovery

P. greenei, P. crassus, and the type species P. frangens were originally classified as a species of Rhynchodus, before being moved to a new genus, Palaeomylus, in 1891. The first was found in Wisconsin, while the latter two species were found in Ohio. P. predator was found near Gerolstein, Germany.[4]
