The hip bones of Spinosaurus were reduced, and the legs were very short in proportion to the body. Its long and narrow tail was deepened by tall, thin neural spines and elongated chevrons, forming a flexible fin or paddle-like structure. Spinosaurus is known to have eaten fish and small to medium terrestrial prey as well. [5]
Spinosaurus had an even smaller pelvis and hindlimbs in proportion to its body size; its legs composed just over 25 percent of the total body length. Substantially complete spinosaurid foot remains are only known from Spinosaurus.
Tameryraptor lived in the Bahariya Formation, then a wetland environment, alongside the coeval Spinosaurus which is also known from the Kem Kem beds. The faunal composition of both the Bahariya Formation and the Kem Kem beds were thought to be similar in the past, but the describers of Tameryraptor suggested that such superficial comparisons ...
The large theropod dinosaur Spinosaurus was until 2014 only known from fragmentary remains, mainly of the skull and vertebrae. It was assumed that the remaining skeleton would look more or less like that of related animals like Baryonyx and Suchomimus, who sport a traditional theropod anatomy of long, strong hind legs and relatively small front ...
The presence of this condition on the Brazilian leg fragment showed that compact bones had already evolved in spinosaurines at least 10 million years before the appearance of Spinosaurus in Morocco. According to phylogenetic bracketing —a method used to infer unknown traits in organisms by comparison with their relatives [ 63 ...
