Thrissops
Thrissops is an extinct genus of stem-teleost fish from the Jurassic period. Its fossils are known from the Solnhofen Limestone, as well as the Kimmeridge Clay.
Thrissops was a fast predatory fish up to long, that fed on other bony fish. It had a streamlined body with a deeply cleft tail and only very small pelvic fins. Thrissops was one of the smaller members of the order Ichthyodectiformes, which also included larger representatives like Xiphactinus and Saurodon.
