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.
Dinosaur tooth. Dinosaur teeth have been studied since 1822 when Mary Ann Mantell (1795-1869) and her husband Dr Gideon Algernon Mantell (1790-1852) discovered an Iguanodon tooth in Sussex in England. Unlike mammal teeth, individual dinosaur teeth are generally not considered by paleontologists to be diagnostic to the genus or species level for ...
Morosauridae. Marsh, 1882. Camarasauridae is a family of sauropod dinosaurs. [1] Among sauropods, camarasaurids are small to medium-sized, with relatively short necks. They are visually identifiable by a short skull with large nares, and broad, spatulate teeth filling a thick jaw. [2][3] Based on cervical vertebrae and cervical rib biomechanics ...
Sauropods were herbivorous (plant-eating), usually quite long-necked [15] quadrupeds (four-legged), often with spatulate (spatula-shaped: broad at the tip, narrow at the neck) teeth. They had tiny heads, massive bodies, and most had long tails. Their hind legs were thick, straight, and powerful, ending in club-like feet with five toes, though ...
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 ...
Cristatusaurus is a genus of theropod dinosaur that lived during the Early Cretaceous Period of what is now Niger, 112 million years ago. It was a baryonychine member of the Spinosauridae, a group of large bipedal carnivores with well-built forelimbs and elongated, crocodile-like skulls. The type species Cristatusaurus lapparenti was named in ...
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 ...
Panphagia was described in 2009 by Ricardo N. Martínez and Oscar A. Alcober, both of the Museo de Ciencias Naturales, in San Juan, Argentina. They performed a phylogenetic analysis and found it to be the most basal known sauropodomorph dinosaur: the fossils shared similar features to those of Saturnalia, an early sauropodomorph, including similarities in the ischium, astragalus, and the ...
