Anchignathodontidae is an extinct conodont family.
Genera are,
Conodonts are an extinct group of jawless vertebrates, classified in the class Conodonta. They are primarily known from their hard, mineralised tooth-like structures called "conodont elements" that in life were present in the oral cavity and used to process food. Rare soft tissue remains suggest that they had elongate eel-like bodies with large eyes. Conodonts were a long-lasting group with over 300 million years of existence from the Cambrian to the beginning of the Jurassic. Conodont elements are highly distinctive to particular species and are widely used in biostratigraphy as indicative of particular periods of geological time.
Promissum is an extinct genus of conodonts, primitive chordates, that lived during the Upper Ordovician period.
Hindeodus is an extinct genus of conodonts in the family Anchignathodontidae. The generic name Hindeodus is a tribute to George Jennings Hinde, a British geologist and paleontologist from the 1800s and early 1900s. The suffix -odus typically describes the animal's teeth, essentially making Hindeodus mean Hinde-teeth.
Archeognathus is a fossilized jaw apparatus of a large predatory conodont from the Ordovician period. Its large size has made classification difficult, and it has historically been compared to conodonts and gnathostomes since its remains were first discovered in Missouri. Complete articulated jaw apparatus of Archeognathus primus are common in the Winneshiek Shale lagerstätte of Iowa, allowing its identity as a conodont to be secured.
Prioniodontida, also known as the "complex conodonts", is a large clade of conodonts that includes two major evolutionary grades; the Prioniodinina and the Ozarkodinina. It includes many of the more famous conodonts, such as the giant ordovician Promissum (Prioniodinina) from the Soom Shale and the Carboniferous specimens from the Granton Shrimp bed (Ozarkodinina). They are euconodonts, in that their elements are composed of two layers; the crown and the basal body, and are assumed to be a clade.
Cordylodontidae is a family of conodonts.
Ozarkodinida is an extinct conodont order. It is part of the clade Prioniodontida, also known as the "complex conodonts".
Ozarkodina is an extinct genus of conodonts in the family Spathognathodontidae.
Paraconodonts (Paraconodontida) are an extinct order of probable chordates, closely related or ancestral to euconodonts. The order contains the superfamily Furnishinacea, itself containing the families Westergaardodinidae and Furnishinidae.
Paracordylodus is an extinct genus of conodonts in the clade Prioniodontida, also known as the "complex conodonts". The species P. gracilis has been recovered from the chert of the Narooma Terrane, a geological structural region on the south coast of New South Wales, Australia.
Idiognathodus is an extinct conodont genus in the family Idiognathodontidae.
Gnathodus is an extinct conodont genus in the family Idiognathodontidae.
Icriodus is an extinct conodont genus in the family Gnathodontidae.
Alternognathus is an extinct conodont genus in the family Elictognathidae. An extensive study on its population dynamics and lifespan has recently been published.
Diplognathodus is an extinct genus of conodonts in the family Anchignathodontidae. Specimens are found in Carboniferous and Permian formations.
Metapolygnathus is an extinct genus of platform conodonts.
Histiodella is an extinct genus of conodonts.
Siphonodella is an extinct genus of conodonts.
Protohertzina is a genus of conodonts or, possibly, Chaetognaths, found at the beginning of the Cambrian explosion.
Panderodus Is an extinct genus of jawless fish belonging to the order Conodonta. This genus had a long temporal range, surviving from the middle Ordovician to late Devonian. In 2021, extremely rare body fossils of Panderodus from the Waukesha Biota were described, and it revealed that Panderodus had a more thick body compared to the more slender bodies of more advanced conodonts. It also revealed that this conodont was a macrophagous predator, meaning it went after large prey.
