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.
Allosaurus (/ ˌæləˈsɔːrəs /) [2][3] is an extinct genus of large carnosaurian theropod dinosaur that lived 155 to 145 million years ago during the Late Jurassic period (Kimmeridgian to late Tithonian ages). The name " Allosaurus " means "different lizard", alluding to its unique (at the time of its discovery) concave vertebrae.
Neanderthal anatomy. Neanderthal anatomy differed from modern humans in that they had a more robust build and distinctive morphological features, especially on the cranium, which gradually accumulated more derived aspects, particularly in certain isolated geographic regions. This robust build was an effective adaptation for Neanderthals, as ...
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 skeleton from ...
Extrapolating from that skull, they estimated the skull of Giganotosaurus to have been 1.634 m (5.36 ft) long, making it one of the largest known theropod skulls. [29] Henderson suggested in 2023 that there was a close relation between the dimensions of the pelvic area and body size in theropods, allowing size estimates for incomplete specimens.
Reconstructed adult and juvenile Spinophorosaurus skeletons (A, B) compared in size with adult and juvenile giraffes (C, D) and a human (E). The holotype specimen was initially estimated to have been around 13 metres (43 ft) in length when measured along the vertebral column, while the paratype was about 13 per cent larger, measuring around 14 m (46 ft).
Human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting. As such, they are considered part of the human digestive system. [1] Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function.
Neither premaxilla bears any teeth, although the very anterior tip has "pseudo-teeth" formed by multiple denticles on the margin of the bone. [1] Only the right maxilla of Ouranosaurus is known. although it is well preserved forming a triangle 28.0 cm (11.0 in) long and 11.7 cm (4.6 in) tall, much taller proportionally than Iguanodon .
