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. [ 48 ] [ 65 ] [ 36 ] 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 ...
A neopterygiian fish, either an ancient loricariid catfish or a juvenile obaichthyid lepisosteiform. [12] Agassizilia [13] A. erfoudina: Possibly a member of the family Pycnodontidae. Agoultichthys [1] A. chattertoni: A long-bodied member of Actinopterygii of uncertain phylogenetic placement. Might be a member of the family Macrosemiidae [14 ...
While there are a variety of options to choose from, dietitians recommend stocking up on a variety of canned beans, fish such as canned salmon and tuna, and canned vegetables and fruits, like ...
The blood grooves (tiny furrows in the gaps between each denticle) of GMNH-PV-999 have an oblique orientation of 45 degrees, as in Baryonyx and KDC-PV-0003, the second Sebayashi formation tooth, which consists of a slightly recurved crown fragment with an almost circular cross-section. It has better preservation of small details than the former ...
The generic name, meaning "fish hunter", refers to its assumed piscivorous lifestyle, while the specific name alludes to the country of Laos. In 2014, it was announced that more remains from the dig site had been recovered; these fossils included teeth, more vertebrae (backbones) and a pubic bone from the same individual.
