features

Hybodus fossil with belemnite rusts in the stomach area in the State Museum of Natural History Stuttgart

They were large predatory fish, some over 2.5 meters long, that fed on fish and cephalopods. The head was big and blunt, the body massive. The upper lobe of the heteroccal caudal fin was drawn out long, the lower lobe relatively small. There was a strong spine in front of each of the two dorsal fins. The pectoral fins were long. The males wore hook-shaped head spikes behind their eyes. The teeth had a broad base, with a major and several minor tips. Smaller gripping teeth sat in the tip of the mouth. The first fossil teeth of Hybodus were found in England in 1845.
