 An astragalus ( ankle bone ) thought to belong to a species of Allosaurus was found at Cape Paterson , Victoria in Early Cretaceous beds in southeastern Australia . It was thought to provide evidence that Australia was a refugium for animals that had gone extinct elsewhere . This identification was challenged by Samuel Welles , who thought it more resembled that of an ornithomimid , but the original authors defended their identification . With fifteen years of new specimens and research to look at , Daniel Chure reexamined the bone and found that it was not Allosaurus , but could represent an allosauroid . Similarly , Yoichi Azuma and Phil Currie , in their description of Fukuiraptor , noted that the bone closely resembled that of their new genus . This specimen is sometimes referred to as " Allosaurus robustus " , an informal museum name . It may have belonged to something similar to , or the same as , Australovenator , or it may represent an abelisaur . A speculative " polar " or " dwarf allosaur " was used for the " Spirits of the Ice Forest " episode of Walking with Dinosaurs .
