In Depth
Although the genus name means crocodile, Walgettosuchus was actually a theropod dinosaur, although the single opalised vertebrae that it is known from has been criticised as not being diagnostic enough to establish a specific genus. As such Walgettosuchus is generally regarded as being what is called a nomen dubium, a genus that cannot be definitively confirmed to exist. Many other Australian dinosaur genera have been named from single bones including Ozraptor, Rapator and Kakuru, the latter two also having opalised fossils.
