The remains of Nigersaurus had been in the beginning explained by Taquet in 1976 as belonging to your dicraeosaurid, but in 1999 Sereno and colleagues reclassified it for a rebbachisaurid diplodocoid.[four] These researchers speculated that considering the fact that short necks and tiny sizing was recognised amongst basal diplodocoids, it could indicate these had been ancestral options with the team.
Regardless of the memes, Nigersaurus stays an extraordinary illustration of evolution and adaptation, deserving recognition for its one of a kind capabilities as opposed to Web controversy.
It further argued that the orientation on the semicircular canals may differ noticeably inside modern-day species, and is as a result not reputable for pinpointing head posture.[23] This was supported because of the Spanish palaeontologist Jesús Marugán-Lobón and colleagues in a 2013 research that instructed the procedures employed by Sereno's group have been imprecise, Which Nigersaurus habitually held its head like other sauropods.[24]
The Nigersaurus roamed the lush landscapes of the center Cretaceous time period, in what has become the Sahara Desert of Niger. This location, at the time teeming with existence, delivered a prosperous tapestry of soft, leafy vegetation that was perfect for the Nigersaurus’s specialized eating plan.

Lifetime restoration Nigersaurus was unique in that its dorsal (back again) vertebrae had paired pneumatic Areas at The bottom with the neural spines (the spines that projected upwards through the vertebrae). The presacral vertebrae (vertebrae in front of the sacrum) have been heavily pneumatised to The purpose the place the column consisted of a series of hollow "shells", Each individual divided by a thin septum in the middle. It had very little to no cancellous bone, building the centra thin bone plates crammed with air Areas. The vertebral arches were being so closely pierced by extensions in the exterior air sacs that in their aspect partitions very little remained but Nigersaurus two mm (0.
Numerous Nigersaurus specimens gathered by French and American expeditions continue to be for being described.[nine] Teeth comparable to Individuals of Nigersaurus are actually located within the Isle of Wight and in Brazil, but it's unfamiliar whether they belonged to relations of this taxon, or to titanosaurs, whose continues to be are already present in the vicinity.
This attribute has captured public consideration, rendering it The most unforgettable aspects of Nigersaurus's biology, particularly in on-line conversations.
Our initial 7 days in the field continues to be amazing! Outstanding discoveries seem to be watching for us close to every dune. On our 1st day, we uncovered bones with the long-necked dinosaur Nigersaurus. Nigersaurus, you would possibly bear in mind, we named for bones collected on the final expedition listed here a few yrs back.
Nigersaurus is really a genus of sauropod dinosaurs that lived somewhere around 115 to 105 million decades in the past through the Early to Mid-Cretaceous period. It belonged to your rebbachisaurids, a subgroup of Diplodocoidea, a clade of very long-necked, herbivorous dinosaurs.
are grouped inside the subfamily Nigersaurinae of your relatives Rebbachisauridae, that's A part of the sauropod superfamily Diplodocoidea. Nigersaurus
This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with greater than 500 replaceable teeth. The original fossil cranium of Nigersaurus
We very carefully brushed the sand off the one hundred ten million-year-outdated bones and dug channels amongst the key regions of the skeleton. Quickly we will cover each area in plaster so which the skeleton is often transported away from the field and back into the laboratory.
We are interested in finding extra than just dinosaurs. We want to locate all animals and crops that when lived together The traditional streams and forests a hundred and ten million yrs back. One of the most typical fossils we encountered in the initial week of work belonged to an infinite crocodile named Sarcosuchus.
