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!

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?

Chris
