Size comparison of Hagryphus. As the specific name indicates, Hagryphus giganteus was a particularly large oviraptorosaur, estimated by the describers to have been approximately three meters (10 ft) long, which makes it one of the largest members of the clade Oviraptorosauria (Barsbold, 1976), apart from the later described Gigantoraptor.
The parietal bones did not project past the squamosals and had V-shaped hind margins, with emargination (a series of notches) spanning their entire width. [2] [7] Diagram showing the skull from above and the left side. The epiossifications on the squamosal bones of Kosmoceratops became progressively larger towards the back of the neck frill ...
Various carnivorans, with feliforms to the left, and caniforms to the right. Carnivora is an order of placental mammals that have specialized in primarily eating flesh. Members of this order are called carnivorans, or colloquially carnivores, though the term more properly refers to any meat-eating organisms, and some carnivoran species are omnivores or herbivores.
The neck frills of ceratopsids are surrounded by the epoccipital bones. [ 9 ] : 66 The name is a misnomer, as they are not associated with the occipital bone . [ citation needed ] Epoccipitals begin as separate bones that fuse during the animal's growth to either the squamosal or parietal bones that make up the base of the frill.
The carnassial pair is made up of the fourth upper premolar and the first lower molar teeth. Like most mammals, the dentition is heterodont , though in some species, such as the aardwolf ( Proteles cristata ), the teeth have been greatly reduced and the cheek teeth are specialised for eating insects.
The researchers named the leopard-size species Bastetodon syrtos as a nod to the cat-headed ancient Egyptian goddess Bastet because of the species’ unique shorter snout compared with other ...
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
Ornitholestes is often portrayed as a fast, long-legged theropod, but its lower limb bones were fairly short. [45] Osborn (1917) calculated that the, missing, tibia (shin bone) was only about 70.6% as long as the femur (thigh bone). [46] The metatarsals (foot bones) were spaced closely, but not fused together. [47]
