Baryonyx

Baryonyx (name meaning "Heavy Claw") is a genus of spinosaurid theropod dinosaur that originated during the Early Cretaceous period in what is now Europe. A relative of Spinosaurus measuring 9 meters long, weighing nearly 2 tons, and named for its very large claw on the first finger, Baryonyx has a long and narrow snout comparable to that of a crocodile.

In the Series 1 episode "The Great Migration", a pair of Baryonyx were lived in their own lifes from Europe 127 million years ago.

Era and Discovery
Baryonyx was lived on England with other Dinosaurs, like Hypsilophodon, Iguanodon, Neovenator and Polacanthus. About 130 million years ago, Baryonyx were once the top predators in Europe. Baryonyx was comfurmed to a netrual dinosaur throwds others. They can eats fish and other dinosaurs, but became extinct, when other dinosaurs survives in Englend.

In‭ ‬1983‭ ‬a fossil hunter named William Walker discovered a large fossilised claw in a clay pit.‭ ‬Retrieval of this claw also resulted in the recovery of associated bones that revealed a new and previously unknown type of theropod dinosaur.‭ ‬Alan Charig and Angela Milner described and formerly named the new dinosaur Baryonyx after the initially discovered large and heavy claw.‭ ‬The species name B. walkeri is in honour of William Walker.

Physical Attributes
Baryonyx is estimated to have been between 7.5 and 10 m (25 and 33 ft) long, 2.5 m (8.2 ft) in hip height, and to have weighed between 1.2 and 1.9 t (1.3 and 2.1 short tons; 1.2 and 1.9 long tons). The fact that elements of the skull and vertebral column of the B. walkeri holotype specimen (NHM R9951) do not appear to have co-ossified (fused) suggests that the individual was not fully grown, and the mature animal may have been much larger (as is the case for some other spinosaurids). On the other hand, the specimen's fused sternum indicates that it may have been mature.

Behavior & Traits
Baryonyx is a theropod dinosaur which lived in the early Cretaceous Period; its a spinosaurid, a member of the same group as the northern African dinosaurs Spinosaurus and Suchomimus. They're territorial and aggressive, living in flooded natural caves that are found along the river. They can mostly eats Fish and Small Dinosaurs, It's more lickly reason that Baryonyx hunts in the river, while open his mouth, they can catch fish on their own by open wide, untill they succsesfull lurying trap, if they are failed to catch fish, the fish most lickly swims away.

they mate during the wet season. In mating season, males and females venture away from the Marshes to pair up privately in coastal caves, remaining there until the season ends. The females will then make their nests near lakes surrounded by dense jungles and will protect their eggs until the day they hatch, with help from their mates. During this time, they become extremely aggressive to any intruders that come near their nests, notably theropods of all sizes, including Tyrannosaurus rex.
