Description

Pteraspis is typical of the pteraspid family of heterostracans,which became very numerous and diverse during the Late Silurian and Early Devonian. Although it lacked paired fins, Pteiaspis was a powerful swimmer, to judge by several hydrodynamic features of its body.

Habitat

It has long, flexible tail was also hydrodynamic, with the lower lobe elongated to provide lift at the front of the body during swimming.Additional

Behaviour

Additional lift was provided by the elongated snout, which was drawn out into a bladelike"ros- trum," below which the mouth opened.

Life History

Paleontologists assumes that Pteraspis and its relatives fed in mid-water or near the surface of the sea, among the shoals of planktonic,shrimplike crustaceans.
