Carolowilhelmina
Encyclopedia
Carolowilhelmina geognostica is an extinct arthrodire placoderm fish that lived in the Late Eifelian epoch (of Middle Devonian) of Spain. It appears a long-snouted pelagic fish
, very similar to the Australian Rolfosteus, from Gogo Formation
. As with Rolfosteus, Carolowilhelmina possessed a long tubular rostral plate, with small postnasal plates and low inferognathal ones. According to Mark-Kurik & Carls (2002), this placoderm may have lived in an pelagic environment with lush, floating algae and epiplankton.

Pelagic fish live near the surface or in the water column of coastal, ocean and lake waters, but not on the bottom of the sea or the lake. They can be contrasted with demersal fish, which do live on or near the bottom, and reef fish which are associated with coral reefs.The marine pelagic...
