Hybodus is instantly recognisable by the spike that rises up in front of its dorsal fins. The purpose of this has been explained as a form of defence from larger predators to display. With fossils dating back from the end of the Permian to the early Cretaceous and a cosmopolitan distribution, Hybodus must have been a highly successful predator.

2019年9月18日 · The most well-known of all of the hybodont sharks is its eponymous member Hybodus, a genus composed of several species which survived and thrived during the dinosaur age. It measured 6 feet long, and it occupied marine habitats around the world, although it is especially known from fossils found in Europe.

Hybodus (from Greek: ύβος hybos, 'crooked' and Greek: ὀδούς odoús 'tooth') is an extinct genus of hybodont that lived from the Middle Triassic to the Late Cretaceous periods. Species closely related to the type species Hybodus reticulatus lived during the Early Jurassic epoch.

The skeletal anatomy of Hybodus fraasi, an Upper Jurassic hybodontid shark from Solnhofen, has been reinvestigated. Its cranial anatomy is very similar to that of H. basanus, a Lower Cretaceous species, and both taxa share certain features not so far identified in Lower Jurassic hybodontids.

The genus "Hybodus" is represented in the fossil records of Asia, Europe, Africa and North America by skeletons, isolated teeth, cephalic and fin spines. According to Maisey (1996: 104-06), these were marine sharks, but some species would enter freshwater.

Hybodus is a prehistoric shark which lived approximately from the Late Permian Period to the Late Cretaceous Period or about 259 to 66 million years ago. Its teeth were first discovered in 1845 in England and this shark was given the name Hybodus – a name which means “humped tooth.”

Hybodus basanus (Agassiz 1837; H. reticulatus (Early Jurassic skull); 2m in length, Permian –Late Cretaceous) nests between sharks and bony fish like tiny Prohalecites. This relationship was overlooked until now.

Hybodus is a hybodontid hybodontiform cartilaginous fish from the Early Jurassic of France, Germany, and the United Kingdom. It was named in 1837 by Louis Agassiz. It was one of the most distinctive extinct sharks to exist; as well as this, it was a …

Hybodus ("humped tooth") is an extinct genus of shark represented in the fossil records of Asia, Europe, Africa and North America by skeletons, isolated teeth, and head and fin spines. The genus first appeared towards the end of the Permian period, and disappearing at the beginning of the Cretaceous (230-90 million years ago).

Hybodonts are an extinct group of sharks that were the dominant sharks for much of the Mesozoic Era following the near-extinction of sharks at the end of the Paleozoic Era. They are characterized by dorsal fin spines and small spines on their heads. There are two lineages of hybodont sharks.
