Spinosaurus is known to have eaten fish and small to medium terrestrial prey as well. [5] Evidence suggests that it was semiaquatic; how capable it was of swimming has been strongly contested. Spinosaurus's leg bones had osteosclerosis (high bone density), allowing for better buoyancy control.
Juvenile spinosaurid fossils are somewhat rare. However, an ungual phalanx measuring 21 mm (0.83 in) belonging to a very young Spinosaurus indicates that Spinosaurus, and probably by extent other spinosaurids, may have developed their semiaquatic adaptations at birth or at a very young age and maintained the adaptations throughout their lives ...
The Cretaceous–Paleogene (K–Pg) extinction event, [a] also known as the K–T extinction, [b] was the mass extinction of three-quarters of the plant and animal species on Earth [2] [3] approximately 66 million years ago. The event caused the extinction of all known non-avian dinosaurs.
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 fossil provides a rare glimpse into a time of global environmental changes and faunal turnover, when some species go extinct while new ones are introduced due to varying changes in the habitat ...
Prehistoric Planet is a British–American nature documentary television series about dinosaurs, that premiered on Apple TV+ beginning May 23, 2022. It is produced by the BBC Studios Natural History Unit, with Jon Favreau as showrunner, visual effects by The Moving Picture Company, and narration by natural historian Sir David Attenborough. [1]
“Its demise is enigmatic considering that it was one of the few Asian great apes to go extinct in the last 2.6 million years, whereas others, including orangutan, survived until the present ...
Suchomimus itself was more adapted to a life hunting in shallow water due to its hollow bones, while Baryonyx and Spinosaurus were capable of fully submerging underwater and diving after prey. Courtesy of denser bones, the latter two spinosaurids could hunt underwater for prey and occupy a more derived lifestyle than Suchomimus could.
