Product information "Placoderm - bony plate"
Placoderms, or armored fish, were the first dominant group of jawed fishes (to which we technically belong as well). They emerged in the Silurian and flourished during the Devonian until the mid-Devonian extinction cut down their diversity and they slowly went extinct toward the end of the Devonian. Like most early fishes they had armor made of bony plates, which were easily preserved.

Very nice specimen!Age: Early Devonian, Emsian, Klerf Fm;Locality: Köppen quarry, Waxweiler, Eifel district Bitburg-Prüm, Rhineland-Palatinate, GermanySize: 7 x 5 x 1 cmPteraspis is an extinct genus of jawless fish that lived during the Devonian period, approximately 419 to 382 million years ago.This primitive aquatic vertebrate belonged to the order Pteraspidiformes and had several notable features:• Protective armored plating covering the front of its body• A streamlined shape with a horn-like rostrum• Wing-like protrusions derived from armored plates over its gills• Stiff spikes on its back, possibly for protection• An estimated length of 20 centimeters (7.9 inches)Despite lacking fins other than its lobed tail, Pteraspis is believed to have been a proficient swimmer due to its streamlined body shape.Pteraspis inhabited both marine and freshwater environments. It is thought to have fed on shoals of plankton near the ocean surface.Colors on photos may differ slightly from the original due to technical reasons.
