Hybodus is a genus of extinct sharks that lived during the Jurassic and Cretaceous periods. The spelling of "Hybodus" is derived from Greek and is pronounced "hi-buh-duhs" using the International Phonetic Alphabet (IPA) phonetic transcription. The "h" is silent, and the "y" is pronounced as a short "i" sound. The "b" and "d" are pronounced as voiced consonants, while the "s" is pronounced as an unvoiced consonant. This spelling accurately represents the pronunciation of this ancient shark genus.
Hybodus is an extinct genus of small to medium-sized shark that lived during the Mesozoic Era, specifically the Jurassic and Cretaceous Periods. It is classified within the family Hybodontidae, which is characterized by sharks that have both cone-shaped teeth for capturing prey and rounded teeth for crushing hard-shelled organisms.
The name "Hybodus" is derived from the Greek words "hybo" meaning "hump" and "odous" meaning "tooth". This name refers to the distinctive hump-like shape on the back of the shark, which is formed by an enlarged dorsal fin spines. The purpose of this hump is still heavily debated among paleontologists.
Hybodus had a streamlined and agile body, with a slightly elongated snout and large eyes positioned on the sides of its head. It possessed an array of small, sharp, and pointed teeth that were ideal for capturing and feeding on a variety of small fish, crustaceans, and invertebrates. Its jaw was capable of rapid snapping movements to seize prey efficiently.
This shark genus had a worldwide distribution, as fossil remains have been found in various locations such as North America, Europe, Africa, Australia, and Asia. Hybodus is considered an important fossil shark due to its abundance in the fossil record, providing valuable insights into the evolution and diversity of early sharks.
Overall, Hybodus was a successful and adaptable shark that thrived for millions of years before its eventual extinction at the end of the Cretaceous Period, alongside many other marine creatures.
In geol., a family of fossil shark-like fishes furnished with teeth having knobbed crowns.

The word "Hybodus" is derived from Greek origins. It is a combination of two Greek words: "hybos" meaning "hump" or "bump" and "odous" meaning "tooth". Therefore, "Hybodus" can be translated as "hump tooth" or "bump tooth", which likely refers to the distinctive bumps or ridges on the teeth of this extinct genus of sharks.
