He learned quite a few fossils from Elrhaz formations in Niger. Amongst These fossils, he found fossils of a brand new dinosaur species that is named Nigersaurus (“Niger Reptile”). He along with other paleontologists gathered a lot of bony parts of Nigersaurus separately and assembled a rough skeleton.
They carved a block of rock that incorporated equally skulls, figuring out entire properly that it could weigh all-around 600 lbs . when encased in plaster.
Judging via the LSC orientation in Nigersaurus, Sereno and corporation hypothesized the animal generally walked around with its snout pointed to the bottom at a 67-diploma angle. Image a moping teen and you'll get The concept.

Nigersaurus and its closest family members are grouped inside the subfamily Rebbachisaurinae (formerly regarded as grouped in the eponymous Nigersaurinae) from the spouse and children Rebbachisauridae, that is Element of the sauropod superfamily Diplodocoidea. Nigersaurus was possibly a browser, and fed with its head close to the bottom. The area of its brain that detected odor was underdeveloped, Even though its brain dimension was corresponding to that of other dinosaurs.
Nigersaurus didn't show exactly the same modifications observed from the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing capabilities. The lessen jaw was L-shaped and divided into the subcylindrical transverse ramus, which contained the teeth, as well as back again ramus, which was additional light-weight and was the location for a lot of the muscle mass attachments. It absolutely was distinct in that the tooth row expanded to the sides from your aircraft of the principle ramus with the reduced jaw.
When Taquet in the beginning explained the dinosaur’s continues to be in the seventies, the formal classification and naming have been executed many years afterwards by Sereno, emphasizing the collaborative nature of its research and discovery.
The trick lies while in the creature’s bones. Researchers might need learned more Nigersaurus fossils If your animal had not had such a delicate bone composition. According to a study by Sereno et al. 2007, this creature had an exceptionally lightweight skull. A lot of the bones in Nigersaurus
The confined knowledge of the genus was the result of lousy preservation of its continues to be, which occurs from the delicate and very pneumatic development (crammed with air Areas linked to air sacs) of the skull and skeleton, in turn leading to disarticulation with the fossils. Some of the cranium fossils were so skinny that a strong light beam was noticeable by way of them. For that reason, no intact skulls or articulated skeletons are already found, and these specimens symbolize by far the most total identified rebbachisaurid stays.[3][one]
This fast tooth alternative, with new teeth expanding just about every 14 days, ensured it preserved sharp edges for grazing on soft vegetation. The special dental arrangement designed it extremely successful at processing low-lying plants, contributing to its name as a specialized herbivore.
Life restoration Nigersaurus was distinct in that its dorsal (again) vertebrae had paired pneumatic spaces at The bottom on the neural spines (the spines that projected upwards through the vertebrae). The presacral vertebrae (vertebrae in front of the sacrum) had been greatly pneumatised to the point wherever the column consisted of a series of hollow "shells", Just about every divided by a thin septum in the center. It had tiny to no cancellous bone, making the centra slim bone plates full of air Areas. The vertebral arches were being so seriously pierced by extensions from the exterior air sacs that in their side partitions little remained but 2 mm (0.
Nigersaurus favored to live in areas having h2o Lakes or streams nearby; the realm is also known as the riparian zone. Due to abundant drinking water, a riparian zone has plenty of minimal-lying vegetation. Riparian zones offer Nigersaurus with numerous types of vegetation.
We are not Nigersaurus speaking about AA Duracells listed here. Dental batteries had been effective food items processing applications employed by lots of plant-having dinos.
The nickname "dinosaur with 500 teeth" comes from Nigersaurus's distinctive dental battery. Its jaw held somewhere around 500 slender teeth, arranged in tightly packed rows, and these teeth ended up continually replaced all through its everyday living.
