Tyrannoneustes is an extinct genus of geosaurine metriorhynchid crocodyliform from the Middle Jurassic Oxford Clay Formation of England. It contains a single species, Tyrannoneustes lythrodectikos, meaning "blood-biting tyrant swimmer".[1][2] The genus was rediscovered after a century of storage in a museum basement after being unearthed by fossil hunter Alfred Leeds between the years of 1907 and 1909. Its lower jaw measured about 26 inches long and its teeth were blade-like, likely built to attack prey as large or larger than itself, similar to the Late Jurassic Dakosaurus, Torvoneustes, and Plesiosuchus.[2]
