Pteraspis prehistoric fish. Computer artwork of two Pteraspis sp. jaw-less fish swimming in a sea during the Devonian period (around 420 to 360 million years ago). Pteraspis lived in what is now Britain and Belgium,and had a protective armoured plating covering the front of its body. It lacked fins but is thought to have been a good swimmer thanks to stiff,wing-like protrusions (white,centre) derived from the armoured plates over its gills | |
