Gallimimus was toothless with a keratinous (horny) beak, and had a delicate lower jaw. Many of the vertebrae had openings that indicate they were pneumatic (air-filled). The neck was proportionally long in relation to the trunk.
Pteranodon skeleton. A toothless Late Cretaceous pterosaur, it was similar to Pelagornis in size and proportions and possibly in feeding habits.. Unlike the true teeth of Mesozoic stem-birds like Archaeopteryx or Ichthyornis, the pseudoteeth of the pelagornithids do not seem to have had serrated or otherwise specialized cutting edges, and were useful to hold prey for swallowing whole rather ...
The skulls of ornithomimosaurs were small, with large eyes, above relatively long and slender necks. The most basal members of the taxon (such as Pelecanimimus and Harpymimus) had a jaw with small teeth, while the later and more derived species had a toothless beak. [9] The fore limbs ("arms") were long and slender and bore powerful claws.
Giganotosaurus (/ ˌ ɡ ɪ ɡ ə ˌ n oʊ t ə ˈ s ɔː r ə s / GIG-ə-NOH-tə-SOR-əs [2]) is a genus of large theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 95 million years ago.
The Siamese tigerfish has the toothless palatine and vomer characteristic of the tiger perches, as is the rounded caudal fin is rounded and rounded lobes on the anal and second dorsal fins creating the appearance of having three caudal fins.

Oviraptor (/ ˈ oʊ v ɪ r æ p t ər /; lit. ' egg thief ') is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous period. The first remains were collected from the Djadokhta Formation of Mongolia in 1923 during a paleontological expedition led by Roy Chapman Andrews, and in the following year the genus and type species Oviraptor philoceratops were named by Henry ...
