So to me, the observations don't support dueling triceratops.<br /><br />I should mention that i suspect strongly that triceratops did fight each other. Most large animals today do (although they are mammals, which may have very different behaviours from dinosaurs), so it seems reasonable and likely that prehistoric large animals also did (but again it could be a mammal thing).<br /><br />Just pointing out, what seems to me, to be a flaw with the argument.andrew f.noreply@blogger.comtag:blogger.com,1999:blog-3467242881996852098.post-33573334311882593522009-03-04T08:15:00.000-08:002009-03-04T08:15:00.000-08:00This comment has been removed by a blog administrator.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3467242881996852098.post-7743209907635362072009-03-04T08:11:00.000-08:002009-03-04T08:11:00.000-08:00This comment has been removed by a blog administrator.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3467242881996852098.post-16530600805646072782009-01-28T22:35:00.000-08:002009-01-28T22:35:00.000-08:00Congratulations on a simple, yet elegant and persu...Congratulations on a simple, yet elegant and persuasive paper!Adam Yateshttps://www.blogger.com/profile/03046084686097124394noreply@blogger.comtag:blogger.com,1999:blog-3467242881996852098.post-32828649199411956512009-01-28T19:13:00.000-08:002009-01-28T19:13:00.000-08:00(and thank you to everyone for your comments - you...(and thank you to everyone for your comments - you are also very welcome to continue the discussion the comments section over at PLoS ONE!)Andyhttps://www.blogger.com/profile/16171447306687358664noreply@blogger.comtag:blogger.com,1999:blog-3467242881996852098.post-63313644537604107412009-01-28T19:12:00.000-08:002009-01-28T19:12:00.000-08:00Oh, you would ask that, wouldn't you, Jordan?!

Couldn't they be used to threaten a predator like Tyrannosaurus rex? <BR/><BR/>However, I'm NOT saying I disagree with the dominance, territorial, display, etc. behavior that we see in mountain goats, stags, etc. today. That does seem more likely than predator defense. But, then, why Triceratops need such a thick frill?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3467242881996852098.post-5220155631926011062009-01-27T20:25:00.000-08:002009-01-27T20:25:00.000-08:00Congrats!!
