Like all sauropods, Nigersaurus was a quadruped with a small head, thick hind legs, and a prominent tail. Among that clade, Nigersaurus was fairly small, with a body length of only 9 m (30 ft) and a femur reaching only 1 m (3 ft 3 in); it may have weighed around 1.9–4 t (2.1–4.4 short tons), comparable to a modern elephant.
Jobaria was a primitive sauropod, about 18.2 metres (60 ft) long and estimated to weigh about 22.4 tonnes (24.7 short tons). [2] In 2016 Gregory S. Paul gave a lower estimation of 16 metres (52 ft) and 16 tonnes (18 short tons). [3] Its backbone and tail were simple compared to the complex vertebrae and whiplash tail of the later North America ...
Unique among sauropods, at least some rebbachisaurids (such as Nigersaurus) are characterised by the presence of tooth batteries, similar to those of hadrosaur and ceratopsian dinosaurs. Such a feeding adaptation has thus developed independently three times among the dinosaurs. So far, rebbachisaurids are known only from the middle and early ...
Unilateral branch stripping is the most likely feeding behavior of Diplodocus, [18] [19] [20] as it explains the unusual wear patterns of the teeth (coming from tooth–food contact). In unilateral branch stripping, one tooth row would have been used to strip foliage from the stem, while the other would act as a guide and stabilizer.
Suchomimus. Suchomimus (meaning "crocodile mimic") is a genus of spinosaur dinosaur that lived between 125 and 112 million years ago in what is now Niger, North Africa, during the Aptian to early Albian stages of the Early Cretaceous Period. It was named and described by paleontologist Paul Sereno and colleagues in 1998, based on a partial ...
Sidersaura was a very large rebbachisaurid. Aside from the controversial giant sauropod Maraapunisaurus which may be a rebbachisaurid, Sidersaura may represent one of the largest known members of this group, at around 18–20 metres (59–66 ft) long and 15 tons in weight.
Elrhaz Formation. The Elrhaz Formation is a geological formation in Niger, West Africa. Its strata date back to the Early Cretaceous, about 125 to 112 million years ago. Dinosaur remains are among the fossils that have been recovered from the formation, alongside those of multiple species of crocodyliformes.
