“It’s a thing that truly normally takes the cake for astounding cranial adaptations With this group, the extended-necked dinosaurs,” claims Sereno, a professor of paleontology for the College of Chicago. “It’s simply a majestic example of evolution.”
Whilst going for walks across a very flat region, Gabe created a exceptional uncover—the bones of a different meat-consuming dinosaur lay partially exposed at her toes. She brushed absent the sand within the higher jaw.

These teeth were being also replaceable (like sharks’ teeth), this means Nigersaurus continually essential contemporary teeth as more mature ones had been worn down or dropped.
8 ft) in size and weighing about two tons. Irrespective of its small size in comparison to other sauropods, it acquired awareness as a result of its unique anatomy, including a wide muzzle resembling a vacuum cleaner and dental batteries consisting of a huge selection of smaller, needle-formed teeth arranged in columns.
Depending on this biomechanical Evaluation, the group concluded that the head and muzzle have been habitually oriented 67° downwards and close to ground level, being an adaptation for ground-level searching. This is often not like how other sauropods happen to be restored, with their heads held more horizontally.[three]
We diligently brushed the sand off the 110 million-year-old bones and dug channels in between the key areas of the skeleton. Quickly We'll go over Every single space in plaster so the skeleton might be transported away from the sector and back again into the laboratory.
Its skull was pretty specialised for feeding. It experienced 4 huge facet fenestrae, openings during the cranium and skinny bones. It had a wide muzzle crammed with in excess of five hundred teeth, which had been replaced around every 14 times. The jaws can have experienced a keratinous sheath, a little something similar to a huge beak. Nigersaurus is the sole recognised tetrapod animal to obtain experienced jaws wider as opposed to cranium and teeth that prolonged laterally across the front.
Head's Up! (Possibly) Due to the fact Nigersaurus ate with its head down, gurus have questioned about its posture. Sereno and his co-authors at the time argued the herbivore aimed its encounter and neck downwards — regardless of whether it was feeding or not — like a matter of behavior.
And what a skeleton it absolutely was! The newfound fossils gave us our first think about the dino's sophisticated dental batteries and vacuum cleaner mouth. Sereno named the species Nigersaurus taqueti — as an homage to French paleontologist Philippe Taquet — in 1999.
Sad to say, this has brought about misunderstandings and occasional misuse in on the internet discussions. Although the attention has sparked curiosity with regards to the dinosaur, Additionally, it underscores the significance of cultural sensitivity and precise conversation when discussing scientific discoveries.
The snout was also proportionately shorter, along with the tooth row was by no means prognathous, the snout suggestion not protruding relative to the rest with the tooth sequence.[1] Nigersaurus was distinct in that its frontal bone (which fashioned much of the skull-roof) was elongate (A great deal narrower than extensive), and experienced a marked cerebral fossa (a despair about the surface of the bone inside the head).[four] The maxillary tooth row was in its entirety transversely rotated, its usual rear ninety° everted in direction of the front. This was matched by The same rotation of the dentary with the reduced jaw. This transverse orientation on the higher and lessen tooth rows was one of Nigersaurus a kind to your dinosaur. Resulting from this configuration, no other tetrapod had all of its teeth Found as considerably to the entrance as Nigersaurus.[three][4]
Nigersaurus did not exhibit the exact same modifications observed within the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing features. The decrease jaw was L-shaped and divided into your subcylindrical transverse ramus, which contained the teeth, along with the back ramus, which was extra light-weight and was the location for most of the muscle mass attachments. It was distinctive in the tooth row expanded to the sides with the plane of the main ramus with the reduced jaw.
The Nigersaurus, with its staggering 500 teeth, offers a captivating distinction to its dinosaur family members, Specially other sauropods. Unlike its cousins with less, thicker teeth, the Nigersaurus’s slender, pencil-like teeth have been uniquely tailored for snipping gentle vegetation, a stark variation within the robust teeth of sauropods like Brachiosaurus, which were very likely meant to deal with harder plants.
