Articles on Spinosaurids are all over. Those pertaining to Baryonyx itself are fewer, but around. One paper we cannot see contains the abstract that follows:
An extremely large claw bone, some 30 cm long, was found in Wealden (Lower Cretaceous) deposits in a Surrey claypit in January 1983. This led to the discovery the following month of the well-preserved skeleton of a new large theropod dinosaur. Only one other theropod specimen comprising more than a few bones had ever been found in Britain, and that discovery was more than a century ago. Indeed, no large theropod, reasonably complete, had previously been discovered in Lower Cretaceous rocks anywhere in the world. Our study so far suggests that the Surrey dinosaur was a typical large theropod in certain respects, resembling, for example Allosaurus 1. In several other respects, however, it differs sufficiently from all known dinosaurs to merit designation as the representative of a new species, genus and family.
A full article I found that is quite interesting is about the discovery of Baryonyx remains in Portugal. As we know, Baryonyx has been found in England, Spain, and Portugal. This paper details what, where, and how the remains were found. It goes on to detail the details of the remains; a set of jaw bone fragments found in the Portuguese cliffs at Boca de Chapim 40 kilometers south of Lisbon.

Two other papers, one by Thomas Holtz and another Christiano Del Sasso et al., discuss more Spinosaurid anatomy, however, Baryonyx is included in the discussions. Del Sasso's article is about new studies on the skull of Spinosaurus and remarks particularly on its construction, size, and shape. Holtz's article, however, does a great deal more on the entire family of the Spinosaurids in that it discusses the entire family as a group of crocodile mimicking dinosaurs. This has been alluded to in past discussions and so his article makes for a very interesting return to topic in that regard. Additionally, it is just that sort of thinking outside the typical box that makes exploring in paleontology so much fun to me personally and so I rather enjoyed reading this out of the norm article; at least it was out of the norm with the other things I have read about Baryonyx to this point I should say.
