The Teeth of 25 Dinosaurs and Other Prehistoric Creatures

THE TEETH OF 25 DINOSAURS AND OTHER PREHISTORIC CREATURES Low growing vegetation ♡ High vegetation o Serrated teeth D Number of teeth Predator Piscivore Omnivore Herbivore 12" 1/2" 1/2“ 8" 1/2"- 1" 5" 6" 3" 1" 14" 0.4" 1" 12" 0.4" 7.5" 7.5" 1"- 0.4" 3" 7.5" 6.5" no teeth 3" wwww AA OD 30 Velociraptor ) 26 Saber-Toothed Tiger D 40 D 24 Dimorphodon OD 64 | Carcharodontosaurus の D72 Ankylosaurus OD 50 Lythronax OD 122 Stenonychosaurus Megalodon Woolly Mammoth Each molar had up to 26| separated ridges of enamel, which helped grind down food. Diplodocus Shuvuuia Quetzalcoatlus Velociraptors relied more on their curved claws to kill prey, stabbing targets and then hiding until the Named after the carcharodon (great white shark) due to the similarity of teeth Replaced slender, peg-like teeth at a rate of one tooth every 35 |days Jaw was not interlocked | with skull, allowing its mouth to open very wide to snatch prey It's theorized that the long length of the front teeth was crucial for reaching the major blood vessels of large mammals. Name means “two-form tooth" in Greek, referring to the two distinct types of teeth it had (fang-like on top, lancet-shaped on bottom) The name "Lythronax" translates to “king of gore" in Greek, referring to its large, vicious teeth and carnivorous nature. Name means "wounding toth" in Greek, referring to the prominent serrations suitable for both meat and plants Their enormous jaws could exert a bite force of up to 40,131 pounds per square inch (five times greater than a T-rex). They could open their jaws more than 7 feet wide! Their massive beaks acted as tweezers, picking out smaller vertebrates from land and streams. Their small, leaf shaped teeth were ideal for |cropping vegetation. prey died. D 64 OD 64 の D800 Triceratops D Hundreds Parasaurolophus Saurornitholestes Spinosaurus OD 60 Tyrannosaurus Rex Closely packed, chise-ike |front teeth suited for |gripping and puling; widely spaced side teeth for tearing flesh OD 78 Allosaurus D 56 D 61 Entelodon (Daeodon) | Analysis of scratches on teeth suggests that they could bite fast and hard down to the bone, despite their modest size. Lack of serrations and Camarasaurus The triceratops had five layers of tissue in its teeth, ideal for both slicing and chewing. Worn teeth were | constantly replaced. Could open their jaws wide and use their teeth like a | hacksaw, taking chunks out of prey; curved teeth |prevented escape Stegosaurus Helicoprion spearlike shape of teeth suggests a diet of fish Teeth were packed into dental batteries suited for grinding down plant material. Worn-out teeth were constantly replaced like a conveyor belt. Its strong, spoon-shaped feeth suggest that it ate fougher plant material than other sauropods did. Greek for "complete teeth," referring to its |complete eutherian dentition (incisors, canines, premolars, molars) OD 52 Fossils contain "teeth-whorls," a spiral of |teeth like a circular saw. They fed on soft prey like squid, their jaw creating a |rolling-back and slicing mechanism. The stegosaurus had toothless beaks and small teeth inside its cheeks. Brachiosaurus DAround 75 teeth Their spoon-shaped teeth were perfect for stripping and chewing vegetation. Kronosaurus Pliosaurus Funkei (Predator X) Believed to have a bite force four times more powerful than a T-rex Kronosaurus teeth lacked sharp edges, but swift speed and colossal force made up for it when hunting prey.
