RE: Spinosaur crests & sails



Hi, this may be old news, but you can check out a large image (photo)of the Irritator challengeri skull!!!!!!, minus that stupidly huge and fake crest, on the home page of Canadian paleontologist Hans-Dieter Sues!

http://www.zoo.utoronto.ca/sues/pict-page.htm

you have to look closely but you can see that the real crest is quite long and low. On the specimen of Angaturama limai, which is just the tip of the snout and likely belongs to the snout less Irritator skull, the crest extends to the tip of the snout. I believe you can (at least could a few months ago, i think that particular section is under construction or something) see a very good life restoration of Irritator/Angaturama done by DML's very own Jaime A. Headden at the dinosauricon.(at least could a few months ago, i think that particular section is under construction or something)

with regards to Spinosaurs swimming, generally all animals are good swimmers and spinosaurs and indeed all theropods were no exception. It is, however, unlikely that they went swimming in pursuit of fish in the manner of crocodiles.


Question? If both taxon prove to be the same animal, which name gets priority?
