Cooyoo is a primitive ichthyodectid found in Lower Cretaceous strata of Queensland, Australia.[1] As with all other ichthyodectids, it was a predator of smaller fish. It is known from complete specimen with length about 1.1 metres (3.6 ft). The type species, named in 1987, is C. australis,[1] although Arthur Smith Woodward originally named it as a species of Portheus (now a probable synonym of Xiphactinus) in 1894, which was later amended to Xiphactinus.
In 2011,[2] 2.5 metres (8.2 ft) long intact fossil of Cooyoo in north-west Queensland is discovered, nicknamed "Wandah". According to Rob Levers, Kronosaurus Korner museum founder and chairman, it was possible to detect the fish in the stomach of that specimen.[3]
