Silurian fish of Europe

Birkenia is a genus of extinct anaspid fish from Middle Silurian strata of Northern Europe, and Middle Silurian to possibly Earliest Devonian strata of Arctic Canada. Birkeniid anaspids are covered by a series of small plates on the head and rod-shaped scales in a cheveron-like pattern on the trunk.

Pteraspidiformes is an extinct order of heterostracan agnathan vertebrates known from extensive fossil remains primarily from Early Devonian strata of Europe and North America, and from Upper Silurian Canada.

Tremataspis is a genus of an extinct osteostracan agnathan from the Silurian period of what is now Estonia. thumb|left|Tremataspis schmidtii head and body armour at the Museum für Naturkunde, Berlin Tremataspis was about in length, and had an armored shield covering its head. Compared with its relatives, the shield was unusually elongated, covering the whole front of the body, and was more rounded in shape, an unusual characteristic for an osteostracan species. It is thought that Tremataspis used its rounder shield to burrow in the ocean floor, searching for food. Because the shield consisted

Phlebolepis is an extinct thelodont agnathan genus belonging to the family Phlebolepididae. Whole fossils are found in Late Silurian (Ludlow epoch) aged strata from Saaremaa, Estonia. Phlebolepis elegans was average-sized for a thelodont, 7 cm long.

Lanarkia is a genus of extinct thelodont agnathan which existed in what is now Scotland and Canada during the upper Silurian period.

Dartmuthia is an extinct genus of primitive jawless fish that lived in the Silurian period. Fossils of Dartmuthia have been found in Himmiste Quarry, on the island of Saaremaa in Estonia. It was first described by William Patten.

Andreolepis is an extinct genus of prehistoric fish, which lived around 420 million years ago. It was described by Walter Gross in 1968 based on scales found in the Hemse Formation in Gotland, Sweden. It is placed in the monogeneric family Andreolepididae and is generally regarded as a primitive member of the class Actinopterygii based on its ganoid scale structure; however some new research regards it as a stem group of osteichthyans.
