That wide muzzle with its Nigersaurus teeth was perfect for scooping up ferns, horsetails and other very low-lying plants. And Together with the bountiful teeth, the dinosaur would've had no problems shearing by way of this vegetation.
Early land plants inhabited a very hot, humid ecosystem. 300 million several years in the past, lots of land locations were protected in soaked forests of giant clubmoss, horsetails and ferns. These seedless plants reproduce with spores, which call for humid environments to outlive.

Nigersaurus is a crucial discovery for paleontologists mainly because it really helps to get rid of mild to the evolution and variety of sauropods during the mid-Cretaceous period.
In Nigersaurus' case, the higher jaws contained sixty columns of modest, needle-shaped higher teeth. And no fewer than 68 very sharp teeth had been present over the reduced jaws. Tallied alongside one another, upper jaw and decreased jaw, the beast experienced greater than 500 specific teeth.
Fossil proof suggests it lived in what is currently the Sahara Desert, feeding on ferns and other vegetation in its lush, riverine habitat.
in 1999, immediately after further plus much more entire remains were located and explained. The genus name implies "Niger reptile", and the particular identify honours the French palaeontologist Philippe Taquet, who uncovered the main remains.
A fresh genus and species of toothless noasaurid ceratosaur has actually been determined from an exceptionally total skeleton found in...
In 2019, Mannion and colleagues pointed out that considering the fact that Nigersaurus was identified to get the sister taxon of all other nigersaurines in some research, a Rebbachisaurinae clade may not automatically consist of Nigersaurus alone (plus the proven fact that the posture of Rebbachisaurus could modify in upcoming analyses), and supported the continued use on the name Nigersaurinae in excess of Rebbachisaurinae for all rebbachisaurids more carefully connected to Nigersaurus than to Limaysaurus.
For example, its fossils suggest that it had a wide, deep ribcage that may have authorized it to soak up substantial amounts of air, facilitating its breathing and delivering the oxygen it needed to maintain its significant system.
It more argued the orientation with the semicircular canals may differ noticeably in just modern species, and is also thus not trusted for analyzing head posture.[23] This was supported via the Spanish palaeontologist Jesús Marugán-Lobón and colleagues in a 2013 study that proposed the techniques utilized by Sereno's workforce had been imprecise, and that Nigersaurus habitually held its head like other sauropods.[24]
The dental structures of Nigersaurus also recommend that they ate delicate crops in massive amounts to meet their nutritional needs. They mainly ate angiosperms, horsetails, and ferns as meals. Quite a few paleontologists also believe that their five hundred closely packed teeth arrangement also functioned similar to a comb. This comb-like teeth arrangement may have also aided them in filtering and taking in aquatic crops.
Skeletal diagram showing recognized factors and sizing comparison Sereno and the American palaeontologist Jeffrey A. Wilson supplied the initial comprehensive description on the cranium and feeding adaptations in 2005.[1] In 2007, a far more thorough description on the skeleton was released by Sereno advert colleagues, based upon a specimen uncovered ten several years previously. The fossils, along with a reconstructed skeleton mount in addition to a plastic product of the head and neck, what dinosaur has 500 teeth were subsequently presented for the Countrywide Geographic Culture in Washington.
What's extra, identical to grazing cows now, these creatures were being ample during their heyday. Following the Preliminary discovery, Sereno discovered A further Nigersaurus specimen all through an expedition in 2000.
