Baryonyx (/ ˌ b ær i ˈ ɒ n ɪ k s /) is a genus of theropod dinosaur which lived in the Barremian stage of the Early Cretaceous period, about 130–125 million years ago.The first skeleton was discovered in 1983 in the Smokejack Clay Pit, of Surrey, England, in sediments of the Weald Clay Formation, and became the holotype specimen of Baryonyx walkeri, named by palaeontologists Alan J ...
This was later confirmed in 1997 with the discovery of partially digested fish scales found in the Baryonyx holotype. [19] In 1998 Sereno and colleagues suggested the same dietary preference for Suchomimus , based on its elongated jaws, spoon-shaped terminal rosette, and long teeth reminiscent of those of piscivorous crocodilians.

Baryonychinae is an extinct clade or subfamily of spinosaurids from the Early Cretaceous of Europe and West Africa.The clade was named by Charig & Milner in 1986 and defined by Sereno et al. in 1998 and Holtz et al. in 2004 as all taxa more closely related to Baryonyx walkeri than to Spinosaurus aegyptiacus.
If these represent Baryonyx’s meal, the animal was, whether in this case a hunter, or a scavenger, an eater of more diverse fare than fish. [ 51 ] [ 67 ] [ 40 ] Moreover, there is a documented example of a spinosaurid having eaten a pterosaur , as one Irritator tooth was found lodged within the fossil vertebrae of an ornithocheirid pterosaur ...
Baryonyx (/ ˌ b ær i ˈ ɒ n ɪ k s /) is a genus of theropod dinosaur which lived in the Barremian stage of the early Cretaceous Period, about 130–125 million years ago. The holotype specimen was discovered in 1983 in Surrey , England , and the animal was named Baryonyx walkeri in 1986.
Baryonyx was found with fish scales and bones from juvenile Iguanodon in its stomach, while a tooth embedded in a South American pterosaur bone suggests that spinosaurs occasionally preyed on pterosaurs, [60] but Spinosaurus was likely to have been a generalized and opportunistic predator, possibly a Cretaceous equivalent of large grizzly bears ...
