ⓘ Thrissops

Thrissops is an extinct genus of teleost fish from the Jurassic and Cretaceous periods. Its fossils are known from the Solnhofen limestone, as well as the Kimmeridge clay.

Thrissops was a fast predatory fish about 60 centimetres 24 in long, which fed on other bony fish. They have a streamlined body with a deeply cleft tail and only very small pelvic fins. Thrissops was related to the giant Xiphactinus and may have been the ancestor of the modern Osteoglossiformes, the most primitive group of living teleosts, which includes the arapaima.
