Updated: After nearly a decade and a half here is the overhauled skeletal. The overall proportions aren't all that different, but some of the details are. The midline crest has been moved back above the lacrimal, and I can now confirm that the odd downcurving neck seems to be a real thing, although it also uses some upwardly deflected almost cervicalized anterior dorsals to achieve it. The gray portion of the ilium is the part that was preserved as an imprint (i.e. there is no surviving bone from those parts) and so its accuracy depends entirely on the observations of the original excavators.
I hope to have more on my blog this weekend.
Previous description: Baryonyx wasn't the first spinosaurid found, but it went a long ways in clarifying what these sorts of theropods looked like and ate. And it turns out they ate fish - although like modern crocodilians, Baryonyx almost certainly ate anything else it could get a hold of too (both fish scales and iguanodont bones were found in its stomach).
