As it was a prey animal, it absolutely was critical for Nigersaurus to get motion hypersensitivity to detect any probable threats.
Nigersaurus didn't show the identical modifications viewed in the jaws of other dinosaurs with dental batteries, or mammals with elaborate chewing functions. The lower jaw was L-formed and divided in the subcylindrical transverse ramus, which contained the teeth, along with the back again ramus, which was a lot more light-weight and was The placement for a lot of the muscle mass attachments. It was distinctive in which the tooth row expanded to the sides through the airplane of the leading ramus on the decrease jaw.
Nigersaurus was named and described in more depth by Sereno and colleagues only in 1999, dependant on remains of newly located people today. Precisely the same post also named Jobaria, another sauropod from Niger. The genus identify Nigersaurus ("Niger reptile") can be a reference for the state where it had been uncovered, and the precise title taqueti honours Taquet, who was the main to organise big-scale palaeontological expeditions to Niger.
Though Taquet at first described the dinosaur’s remains during the seventies, the formal classification and naming had been done a long time later on by Sereno, emphasizing the collaborative nature of its study and discovery.
The dental construction of Nigersaurus provides priceless insights into the dietary and ecological adaptations of sauropods. Its exceptional dental arrangement and immediate tooth substitute system emphasize the varied evolutionary 500 teeth dinosaur approaches that dinosaurs employed to prosper inside their environments.
” Our first week in the sector has been spectacular! Amazing discoveries seem to be looking forward to us all around each and every dune. On our initial working day, we discovered bones from the extended-necked dinosaur Nigersaurus. Nigersaurus, you may don't forget, we named for bones gathered on the final expedition right here three decades in the past.
Following the iguanodontian Lurdusaurus, Nigersaurus was essentially the most many megaherbivore. Other herbivores within the exact same development contain Ouranosaurus, Elrhazosaurus, and an unnamed titanosaur. With each other, these compose one of the number of associations of megaherbivores using a balance of sauropods and large ornithopods.

The identify "Nigersaurus" has started off controversy and dialogue during the scientific Local community and outside of as a consequence of its potential for misinterpretation and unintended connotations.
Horsetails (Equisetum) Have a very central, hollow stem with whorls of leaves or skinny branches. They hold their spores inside a cigar-formed “cone” at the best of your plant. Horsetails day back again to ~370 million several years back. For the duration of the start of the dinosaur era they grew to be approximately thirty ft tall (10m.)
Nigersaurus is thought to get lived in what is currently modern day-working day Niger, Africa, hence its name. It absolutely was to start with found out during the early 2000s by a workforce of paleontologists led by Paul Sereno.
What's additional, identical to grazing cows nowadays, these creatures had been plentiful during their heyday. Once the First discovery, Sereno observed A different Nigersaurus specimen for the duration of an expedition in 2000.
