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 ...
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.

I've recreated my Ostafrikasaurus size comparison using the same format and style as my Afrovenator chart, I based it off of Baryonyx, particularly Scott Hartman's skeletal. The original never went up for review anyways, so, better late than never. >>: PaleoGeekSquared ( Talk ) ( Contribs ) 20:48, 10 January 2018 (UTC) [ reply ]
Regardless of speculation, I think this would be more useful as two separate images: the skeletal diagram and the fossil illustration. - SlvrHwk ( talk ) 02:48, 22 February 2022 (UTC) as suggested by User:SlvrHwk , I have created separate files for the skeletal diagram and the fossil illustration.
Diagram by Dan Folkes showing known material of Riparovenator (front) and Ceratosuchops (rear) Between 2013 and 2017, spinosaurid fossils were uncovered at the beach near the Chilton Chine before being brought to Dinosaur Isle. Such remains had historically been referred to Baryonyx but were understood later to represent two new species. [1]
Reconstructed skeleton of the spinosaurine Irritator, mounted at the National Museum of Nature and Science, Tokyo. In 2012, Allain and colleagues assigned Ichthyovenator to the Spinosauridae; more precisely to the subfamily Baryonychinae in a basal position as the sister taxon of a clade formed by Baryonyx and Suchomimus.

The type and only species is Protathlitis cinctorrensis, known from a partial skeleton. It was a basal member of the Baryonychinae . [ 1 ] Its discovery, as well as those of the spinosaurids Camarillasaurus , Iberospinus , Riojavenatrix , and the contemporary Vallibonavenatrix shows that the Iberian Peninsula held a diverse assemblage of ...
