The type species of Dynatoaetus and the larger of the two. Fossils of this species are known from multiple regions of South Australia, including the Lake Eyre Basin, as well as New South Wales. The species name was chosen to honor Priscilla Gaff, who was the first to discuss the fossil material of this animal in a 2002 thesis. [3] [4]
The species is among the largest raptors in Africa, next to the lappet-faced vulture. With a mean body mass of roughly 8.9 to 9.22 kg (19.6 to 20.3 lb), it appears to be significantly heavier than wild lappet-faced vultures, despite the latter's extremely large appearance, and rivals only a few other species, namely the great white pelican and ...
Birds of prey (raptors) are known to display patterns of sexual dimorphism. It is commonly believed that the dimorphisms found in raptors occur due to sexual selection or environmental factors. In general, hypotheses in favor of ecological factors being the cause for sexual dimorphism in raptors are rejected.
The fossil remains of this raptor, scientifically known as Murusraptor barrosaensis, were discovered in 2000. It took University of Alberta paleontologist Philip Currie and his team until recently ...
Size of two specimens compared to a human. South American megaraptorids were generally very large, exceeding 7 m (23 ft) in length and 1 t (1,000 kg) in mass. [6] The holotype of Megaraptor was estimated by Fernando Novas to measure around 8 m (26 ft) in length. [1]
The latest study highlights the role played by Australia’s dinosaurs in the ecosystems of the ancient world, a large part of which was clustered into the giant supercontinent Gondwanaland. These ...

Size comparison of megaraptorids. Megaraptorans were medium to large-sized theropods, ranging from Fukuiraptor, which was about 4.2 meters (13.8 feet) in length, to the 9 meter (30 feet) long Aerosteon, the 9 to 10 meter (30 to 33 feet) long Maip [5] and the 12.8 meter (42 foot) long Bahariasaurus, if it is a member.
