In mammalian oral anatomy, the canine teeth, also called cuspids, dogteeth, eye teeth, vampire teeth, or fangs, are the relatively long, pointed teeth. In the context of the upper jaw, they are also known as fangs. They can appear more flattened, however, causing them to resemble incisors and leading them to be called incisiform. They developed ...
Creodonta ("meat teeth") is a former order of extinct carnivorous placental mammals that lived from the early Paleocene to the late Miocene epochs in North America, Europe, Asia and Africa. Originally thought to be a single group of animals ancestral to the modern Carnivora , this order is now usually considered a polyphyletic assemblage of two ...
The number of teeth and their function can vary widely between species, with some dolphins having over a hundred teeth in their jaws, while the narwhal has two functional teeth in its upper jaw which grow into long tusks in males. The tusk is used in feeding, navigation and mating and contains millions of sensory pathways, making it the most ...
Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in Asia, Africa, North America, South America, and Europe, with the earliest species known from the Middle Miocene, with the last surviving species (belonging to the genera Smilodon and Homotherium) becoming extinct around Late Pleistocene-Holocene transition (~13-10,000 years ago).

The molar teeth of Palaeoloxodon species typically show a "dot-dash-dot" wear pattern, [16] with the enamel folds concentrated into a major central structure at the midline of the tooth, which are flanked by smaller folds on either side, and the crowns of the tooth are generally proportionally narrow. [17]
It is the other prehistoric mammal that shares the record for the longest name of any vertebrate animal. [43] [44] [45] Thalassorhabdomicrobium marinisediminis Zhao et al. 2019 - family Hyphomonadaceae. An aerobic, Gram-negative bacterium isolated from marine sediments collected in the Bohai Sea, China. Its name means "a rod-shaped microbe of ...
Along with its relative Albertonectes, it was one of the longest-necked animals to have lived, with the second largest number of neck vertebrae known, 72, 4 fewer than Albertonectes. The skull would have been slender and triangular, with large, fang-like teeth at the front, and smaller teeth towards the back.
