Cladoselache is an extinct genus of shark-like chondrichthyan (cartilaginous fish) from the Late Devonian of North America. It was similar in body shape to modern lamnid sharks (such as mako sharks and the great white shark ), but was not closely related to lamnids or to any other modern ( selachian ) shark.
Helicoprion is a genus of extinct shark-like [1] eugeneodont fish. Almost all fossil specimens are of spirally arranged clusters of the individuals' teeth, called "tooth whorls", which in life were embedded in the lower jaw. As with most extinct cartilaginous fish, the skeleton is mostly unknown.
The book received positive reviews, with reviewers noting that though it was based on a TV series, it also stood on its own as an information source about extinct sea creatures. In 2011, an exhibition based on the series, the Sea Monsters Exhibition, was held at Bournemouth International Centre in Dorset. In addition to imagery from the series ...
Akmonistion is an extinct genus of cartilaginous fish that lived in the Early Carboniferous. The genus contains a single species, A. zangerli , discovered by Stan Wood in 1982.
