Baryonyx is an aquatic predator that roamed the Earth during the Early Cretaceous period. It was found in England, UK and it is England´s most famous dinosaurs.

Baryonyx (Baryonyx walkeri) belongs to the spinosaurids theropod group of dinosaurs and lived approximately 130 to 125 million years ago. Its name translates to "heavy claw," referring to the distinctive enlarged claw on its first finger. Baryonyx was first discovered in 1983 in Surrey, England, by amateur fossil hunter William J. Walker, and its subsequent study has provided valuable insights into the diversity and adaptations of early Cretaceous theropods.

Baryonyx was a medium-sized dinosaur, measuring around 8 to 10 meters in length and weighing up to 2 tons. One of its features was the elongated and narrow snout, equipped with numerous sharp, conical teeth specialized for capturing slippery prey. Additionally, Baryonyx possessed long, curved claws on its forelimbs, particularly the first finger, which likely aided in hunting and securing prey.
