Sarcosuchus has an expansion at the end of its snout known as a bulla, which has been compared with the ghara seen in gharials. However, unlike the ghara, which is only found in male gharials, the bulla is present in all Sarcosuchus skulls that have been found so far, suggesting that it was not a sexually dimorphic trait. The purpose of this ...
It is where remains of Sarcosuchus imperator, popularly known as SuperCroc, were found (by Paul Sereno in 1997, for example), including vertebrae, limb bones, armor plates, jaws, and a nearly complete 6 feet (1.8 m) skull. Dinosaurs of Elrhaz formation The claw of Spinosaur from the formation. Gadoufaoua is very hot and dry.
Crocodylomorphs like Sarcosuchus, Anatosuchus, Araripesuchus, and Stolokrosuchus also lived there. In addition, remains of a pterosaur, chelonians, fish, a hybodont shark, and freshwater bivalves have been found. The aquatic fauna consists entirely of freshwater inhabitants. [3] [26]
Neosuchia is a clade within Mesoeucrocodylia that includes all modern extant crocodilians and their closest fossil relatives. [1] It is defined as the most inclusive clade containing all crocodylomorphs more closely related to Crocodylus niloticus (the Nile Crocodile) than to Notosuchus terrestris. [2]
Pholidosaurus purbeckensis fossil.. Pholidosauridae is an extinct family of aquatic neosuchian mesoeucrocodylian crocodylomorphs. Fossils have been found in Europe (Denmark, England, France, Germany, Spain and Sweden), Africa (Algeria, Niger, Mali, Morocco and Tunisia), North America (Canada and the United States) and South America (Brazil and Uruguay).
The name Pseudosuchia was originally given to a group of superficially crocodile-like prehistoric reptiles from the Triassic period, but fell out of use in the late 20th century, especially after the name Crurotarsi was established in 1990 to label the clade (evolutionary grouping) of archosaurs encompassing most reptiles previously identified as pseudosuchians.

P. kirkpatricki compared to a human. Postosuchus was one of the largest carnivorous reptiles during the late Triassic. The length of the paratype is estimated up to 3.5–4 m (11–13 ft) long, [3] and an individual of such length would have measured 2 metres (6.6 ft) tall at the head when stood upright and weighed around 250–300 kilograms (550–660 lb).
