Xenodens (from Greek and Latin for "strange tooth") is a potentially dubious extinct genus of marine lizard belonging to the mosasaur family. It contains a single species, X. calminechari (From Arabic کالمنشار, meaning "like a saw"), which is known from Late Maastrichtian phosphate deposits in the Ouled Abdoun Basin, Morocco.
Like all sauropods, Nigersaurus was a quadruped with a small head, thick hind legs, and a prominent tail. Among that clade, Nigersaurus was fairly small, with a body length of only 9 m (30 ft) and a femur reaching only 1 m (3 ft 3 in); it may have weighed around 1.9–4 t (2.1–4.4 short tons), comparable to a modern elephant.
The genus contains a single species, M. provincialis, which is known from a single maxilla and associated teeth. It was named by Pascal Godefroit and colleagues in 2017. The teeth of Matheronodon are large but few in number. The teeth are also in an unusual arrangement, emerging alternatingly from one of a pair of fused tooth sockets in its mouth.
The fish range in size from about 3.83 inches to about 4.86 inches long, the study said. They were collected from between approximately 630 feet underwater to about 985 feet underwater.
The two envisioned the living animal to have a long and very narrow skull, creating a long nose akin to the modern-day goblin shark. [34] A 1996 textbook by Philippe Janvier presented a similar reconstruction, albeit with sharp teeth at the front of the upper jaw and rows of low crushing teeth in the back of the jaw. [35]
The teeth-like fossils of the conodont were first discovered by Heinz Christian Pander and the results published in Saint Petersburg, Russia, in 1856. [2]It was only in the early 1980s that the first fossil evidence of the rest of the animal was found (see below).
Dicynodontia is an extinct clade of anomodonts, an extinct type of non-mammalian therapsid.Dicynodonts were herbivores that typically bore a pair of tusks, hence their name, which means 'two dog tooth'.
This gave the upper jaw the appearance of a "zipper smile of little teeth". The upper jaw was believed to have hooked downwards. [6] Discoveries in 2016, however, overthrew these findings, and revealed that Atopodentatus actually had a hammer-shaped head, with a bank of chisel-shaped teeth, that was useful in rooting the seabed for food.
