Erepsilepis is an extinct thelodont agnathan genus in the family Phlebolepididae. [1]
Agnatha is an infraphylum of jawless fish in the phylum Chordata, subphylum Vertebrata, consisting of both present (cyclostomes) and extinct species. Among recent animals, cyclostomes are sister to all vertebrates with jaws, known as gnathostomes.
Ostracoderms are the armored jawless fish of the Paleozoic Era. The term does not often appear in classifications today because it is paraphyletic and thus does not correspond to one evolutionary lineage. However, the term is still used as an informal way of loosely grouping together the armored jawless fishes.
Thelodonti is a class of extinct jawless fishes with distinctive scales instead of large plates of armor.
Thelodus is an extinct genus of thelodont agnathan that lived during the Silurian period. Fossils have been found in Europe, Asia and North America. Unlike many thelodonts, species of Thelodus are known not only from scales, but from impressions in rocks. Some species, such as the Canadian T. inauditus, are thought to be comparable in size to other thelodonts, i.e., from 5 to 15 centimeters in length. The scales of the type species, T. parvidens of Silurian Great Britain, however, reach the size of coins, and, if proportioned like other thelodonts, such as Loganellia, the living animal would have been about one meter in length.
Phlebolepis is an extinct thelodont agnathan genus belonging to the family Phlebolepididae. Whole fossils are found in Late Silurian aged strata from Saaremaa, Estonia. Phlebolepis elegans was average-sized for a thelodont, 7 cm long.
The Rhyparochromidae are a large family of true bugs, many of which are commonly referred to as seed bugs. The family includes two subfamilies, more than 420 genera, and over 2,100 described species.
Stroinolepis is a genus of thelodontid that lived during the Middle Ordovician period in what is now Russia.
Drepanolepis is an extinct genus of thelodont which lived in Canada during the Early Devonian period. They are considered a "traditional" thelodont and are classified by their forked tails.
Longodus is an extinct genus of thelodont, placed in its own family – Longodidae – which existed in what is now Estonia during the Ludlow epoch of the upper Silurian period. The type and only species is Longodus acicularis. They are most noted for their long, needle-like scales, which run vertically along their trunk.
Lanarkia is a genus of extinct thelodont agnathan which existed in what is now Scotland and Canada during the upper Silurian period.
Canonia is an extinct genus of jawless fish found in Canada.
Furcacaudiformes is an extinct order of jawless fish in the class Thelodonti.
Coelolepis is an extinct genus of jawless fish of the Silurian.
Thelodontiformes is an extinct order of jawless fish of the Silurian.
Archipelepidiformes is an order of extinct jawless fishes in the class Thelodonti.
Archipelepis is a genus of extinct thelodont agnathans, and are the most primitive recognized thelodonts of which whole body fossils are known. Fossils of bodies and scales are currently known from Late Telychian to Wenlock-aged marine strata of northern Canada.
Phlebolepididae is an extinct thelodont agnathan family in the order Phlebolepidiformes.
Loganelliidae is an extinct family of thelodonts in the order Thelodontiformes. They are distinguished by the star or cross shaped ridges located on their head scales.
Oeselia mosaica is a fossil jawless fish and is the only species in its genus and in the family Oeseliidae. It is a member of an extinct family of thelodonts or jawless fishes. The family and genus were established along with the description of the species by Tiuu Märss in 2005.
