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 ...
Datnioides tiger perches are characterised by having toothless palatine and vomer. The caudal fin is rounded and there are rounded lobes on the anal and second dorsal fins creating the appearance of having three caudal fins. The dorsal fin is supported by 12 spines and 15 or 16 soft rays. [4]
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.
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. [9] This species has 4, occasionally 5, wide vertical bars on the orange-brown body.
The fossilised Steropodon was discovered in New South Wales and is composed of an opalised lower jawbone with three molar teeth (whereas the adult contemporary platypus is toothless). The molar teeth were initially thought to be tribosphenic , which would have supported a variation of Gregory's theory, but later research has suggested, while ...

The type species, Struthiomimus altus, is one of the more common, smaller dinosaurs found in Dinosaur Provincial Park; their overall abundance—in addition to their toothless beak—suggests that these animals were mainly herbivorous or (more likely) omnivorous, rather than purely carnivorous. Similar to the modern extant ostriches, emus, and ...
