Dinosaurs 500 teeth

Nigersaurus lived in a lush environment alongside the predatory dinosaur Suchomimus, the plant eaters ouranosaurus and lurdusaurus, dinosaurs 500 teeth, and supercroc. Nigersaurus had a delicate skull and an extremely wide mouth lined with teeth especially adapted for browsing plants close to the ground. This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with more than replaceable teeth.

That nickname was given to the African dinosaur Nigersaurus taqueti — back when some new discoveries about its appearance were made public in What dinosaur has teeth? An unorthodox herbivore, this reptile grazed in what's now the Sahara Desert million years ago. These sauropod dinosaurs gathered food with a big, broad mouth; the snout was wider than the back of the creature's head on the original fossil skull. Calling something "elephant-sized" usually means it's quite big, if not downright enormous.

He was excavating bones in a dry region called Gadoufaoua, which had a rich fossil bed first discovered by French uranium miners. There were a lot of light, aerated bones — usually associated with theropods, like Tyrannosaurus rex, and the birds that evolved from them — so the researchers assumed that was what they were dealing with. As Sereno began to piece together the fossils, he realized it must be a sauropod, or long-necked dinosaur. Most of the bones appeared fairly typical for long-necked dinosaurs —except for its bizarrely-shaped head. Eventually, back in the lab, Sereno had to ask for a second opinion from colleagues who worked on fossil fish and other reptiles before he figured it out. There are a lot of strange-looking dinosaurs out there. The sauropod's jaw looks almost like a large nail clipper, with large rows of hundreds of teeth on its upper and lower jaws. But compared to other sauropods, it was relatively small — sitting somewhere between an African and Indian elephant in size. The dinosaur's vertebrae was filled with air pockets similar to those of birds, so the dinosaur was likely quite light, as well. Its brain was about the size of a walnut, which is more or less average for sauropods, Sereno says. Its head is what really stands out about Nigersaurus , though. The jaws, which have a flat front, are lined with about teeth, which Sereno says were replaceable.

While other heavy animals examined such as rhinoceroses had thick and variable bone corticesthe cortex of Nigersaurus was rather thin, dinosaurs 500 teeth. We carefully dinosaurs 500 teeth the sand off the million-year-old bones and dug channels between the major areas of the skeleton. The vertebral arches were so heavily pierced by extensions of the external air sacs that of their side walls little remained but 2 mm 0.

It was discovered in the Elrhaz Formation in an area called Gadoufaoua , in Niger. Fossils of this dinosaur were first described in , but it was only named Nigersaurus taqueti in , after further and more complete remains were found and described. The genus name means "Niger reptile", and the specific name honours the palaeontologist Philippe Taquet , who discovered the first remains. Small for a sauropod, Nigersaurus was about 9 m 30 ft long, and had a short neck. It weighed around 1.

The original fossil skull of Nigersaurus is one of the first dinosaur skulls to be digitally reconstructed from CT scans. Our first week in the field has been spectacular! Remarkable discoveries seem to be waiting for us around every dune. On our first day, we found bones of the long-necked dinosaur Nigersaurus. Nigersaurus, you might remember, we named for bones collected on the last expedition here three years ago.

Bibcode : NatSR.. Nigersaurus wasn't just small-bodied for a sauropod, it also had a fairly short neck. It had little to no cancellous bone , making the centra thin bone plates filled with air spaces. Bibcode : PLoSO They also made an endocast of the brain and scanned the semicircular canals of its inner ear , which they found to be oriented horizontally. There were a lot of light, aerated bones — usually associated with theropods, like Tyrannosaurus rex, and the birds that evolved from them — so the researchers assumed that was what they were dealing with. The limbs were not as specialised as the rest of the skeleton, and the front legs of Nigersaurus were about two-thirds the length of the back legs, as in most diplodocoids. Recommendations From Our Store. Scientists probably would've found more Nigersaurus remains a whole lot sooner if it hadn't been for this animal's fragile bone structure. Like today's birds, many prehistoric dinosaurs had hollow bones containing air sacs. Microcoelus Mongolosaurus?

This is unlike the way other sauropods have been restored, with their heads held more horizontally. You see, Nigersaurus was a sauropod. While other heavy animals examined such as rhinoceroses had thick and variable bone cortices , the cortex of Nigersaurus was rather thin. The same article also named Jobaria , another sauropod from Niger. The front ends of the jaws had grooves that indicate the presence of a keratinous horny sheath. Contents move to sidebar hide.
