Carnotaurus is the only known carnivorous bipedal animal with a pair of horns on the frontal bone. [45] The use of these horns is not entirely clear. Several interpretations have revolved around use in fighting conspecifics or in killing prey, though a use in display for courtship or recognition of members of the same species is possible as well.
This list of non-avian theropod type specimens is a list of fossils that are the official standard-bearers for inclusion in the Mesozoic species and genera of the dinosaur clade Theropoda, which includes the carnivorous dinosaurs like Tyrannosaurus and Velociraptor, their herbivorous relatives like the therizinosaurs, and birds.
Found in articulation, with the bones still connected to each other, it was nearly complete, including the skull. Significant missing parts include an unknown number of vertebrae, all but the last ribs of the trunk, the humeri (upper arm bones), the distal finger bones of both hands, most of the right arm, most of the left leg, and most of the ...
Carnivory can be inferred for Teleocrater from the single tooth that was preserved, which is compressed, recurved, and bears serrations on both edges. Like other members of the Archosauria, the recess in the maxilla in front of the antorbital fenestra (the antorbital fossa) extends onto the backward-projecting process of the bone, and the palatal projection of the two maxillae contacted each ...
Liopleurodon (/ ˌ l aɪ oʊ ˈ p l ʊər ə d ɒ n /; meaning 'smooth-sided teeth') is an extinct genus of carnivorous pliosaurid pliosaurs that lived from the Callovian stage of the Middle Jurassic to the Kimmeridgian stage of the Late Jurassic period (c. 166 to 155 mya).
They grow from a permanent outgrowth of the frontal bone called the pedicle and can be branched, as in the white-tailed deer (Odocoileus virginianus), or palmate, [31] as in the moose (Alces alces). Ossicones are permanent bone structures that fuse to the frontal or parietal bones during an animal's life and are found only in the Giraffidae.
The bones have been found relatively intact — the ribs somewhat jumbled, for example, but not scattered over a wide area. Tour information Go to coyotecanyonmammothsite.org to register starting ...
The material, a collection of 56 bones or bone fragments, was found in 1853 or 1854 by the government surveyor Joseph Millard Orpen and his brothers on a farm in the Drakensberg mountains near Harrismith, South Africa, and was donated to the Hunterian Museum at the Royal College of Surgeons in London, of which Owen was curator.
