A toothless advanced genus of Enantiornithes, possessing a robust beak which convergently evolved with those of modern birds Jibeinia: 1997: Qiaotou member of the Huajiying Formation (Early Cretaceous, Aptian?) China: Poorly known and described from a skeleton which has now been lost. May have been synonymous with Vescornis: Vescornis: 2004
Millions of years ago, a bird-like dinosaur, known as the “chicken from Hell,” roamed the North American continent. Weighing around 170 pounds, it sported a toothless beak and was blanketed by ...
Skull and beak of specimen AMNH 7515. Unlike earlier pterosaurs, such as Rhamphorhynchus and Pterodactylus, Pteranodon had toothless beaks, similar to those of birds. Pteranodon beaks were made of solid, bony margins that projected from the base of the jaws. The beaks were long, slender, and ended in thin, sharp points.
The monotreme platypus has what looks like a bird's beak (hence its scientific name Ornithorhynchus), but is a mammal. [38] However, it is not structurally similar to a bird beak (or any "true" beak, for that matter), being fleshy instead of keratinous. Red blood cells in mammals lack a cell nucleus.
Members of the group possessed a horny, typically toothless beak, unique amongst all synapsids. Dicynodonts first appeared in Southern Pangaea during the mid-Permian, ca. 270–260 million years ago, and became globally distributed and the dominant herbivorous animals in the Late Permian, ca. 260–252 Mya.
The skull was near triangular in side view, and the toothless beak was robust and pointed. The front of the jaws had deep neurovascular foramina and grooves, associated with the keratinous rhamphotheca (horn-covered beak). The skull was rather robust, with deep jaws, especially the mandible.
As a news release by the University of Edinburgh states, "The two-legged animal belongs to a family of feathered dinosaurs called oviraptorosaurs, characterised by having short, toothless heads ...
Ornithomimus was a swift, bipedal dinosaur which fossil evidence indicates was covered in feathers and equipped with a small toothless beak that may indicate an omnivorous diet. It is usually classified into two species: the type species, Ornithomimus velox, and a referred species, Ornithomimus edmontonicus.
