Crocs, for example (a closer cousin to dinosaurs than moniters) tend to engage in mob-like activity, but to my recollection aren't as outright cannibalistic.<BR/><BR/>Also, regarding the Albertosaurus bonebed, I seem to recall the big news surrounding that one being the <I>presence</I> of juveniles and sub-adults, not the lack of them.<BR/><BR/>Again, a good interpretation of the paper, but at the same time we shouldn't take the same sweeping approach we used to first paint these bonebeds as pack hunts and use it to repaint them all as absolute cannibalistic mobs. We should still give consideration to environmental possibilities like predator traps and other types of common animal gregariousness in the same breath that we consider mob rule.Unknownhttps://www.blogger.com/profile/04732230557631129955noreply@blogger.comtag:blogger.com,1999:blog-38902250.post-11843314606031369632007-08-05T13:58:00.000-07:002007-08-05T13:58:00.000-07:00Nice treatment of Dromeosaur hunting behavior, and...Nice treatment of Dromeosaur hunting behavior, and a good reminder of the pitfalls of taking analogical reasoning too far. Your theropod as varanid model certainly falls closer to the facts than the theropod as canid or even theropod as 'raptor' (sensu-stricto).<BR/><BR/>I would contest that the list of pack hunting in amniotes runs a bit longer than just wolves and hunting dogs. Harris Hawks supposedly hunt in extended family or even polyandrous packs (not just mated pairs), orcas cooperate in taking down large whales, chimps (like their weirdo cousins) group hunt and share the spoils, lions work together together on buffalo kills. <BR/><BR/>Perhaps my examples don't qualify as true 'pack hunting' for one reason or another, but as Brian notes there's a broad continuum from Komodo 'mobbing' to wolves harrying an elk across tens of kms. At any rate, these extant exceptions still prove the rule that cooperative hunting today is rare, and is largely restricted to mammals. <BR/><BR/>Did you hear the one about the <A HREF="http://dml.cmnh.org/1997Feb/msg00472.html" REL="nofollow">nile monitors taking down a croc!?</A> I'd love to get that pdf if you get a chance!Neilhttps://www.blogger.com/profile/10293693723899837239noreply@blogger.comtag:blogger.com,1999:blog-38902250.post-46379254790143917842007-08-05T08:27:00.000-07:002007-08-05T08:27:00.000-07:00Very good post.

You've forgotten about humans.<BR/><BR/>There is probably also an interesting debate about exactly what is or is not 'pack hunting'.themaidenhttps://www.blogger.com/profile/13290311204261204102noreply@blogger.comtag:blogger.com,1999:blog-38902250.post-55990361981068351282007-08-02T14:34:00.000-07:002007-08-02T14:34:00.000-07:00you've gotta be fuckin' kidding me. you realize th...you've gotta be fuckin' kidding me. you realize that this post isn't a post at all? it's a fucking college-style 12-page goshdamn THESIS. by the time i finish reading the damn thing, some asshole will have already CLONED a fucking dinosaur.<BR/><BR/>i'll get around to it though. maybe i'll just read fourteen paragraphs a day. by the time i'm finished, i'll only be THIRTY.lantarohttps://www.blogger.com/profile/16569221441995469045noreply@blogger.comtag:blogger.com,1999:blog-38902250.post-91680958556068349302007-08-02T11:58:00.000-07:002007-08-02T11:58:00.000-07:00Excellent work, Zach!

I always wondered about <I>Deinonychus</I> pack hunting, mostly because I had never seen any evidence for it in popular circles; it's just what they always did. While I haven't seen it in the literature yet either, I have heard of the idea that <I>Tyranosaurus</I> might have had a septic bite, attacking much like a Komodo dragon where an initial, hard attack is made, but if the prey escapes it would soon die of injuries and infection, the loads of bacteria being provided by the carcasses <I>Tyrannosaurus</I> would come across here and there.<BR/><BR/>I'm also reminded of spotted hyena; we think of them hunting in packs, but much hunting is done alone. Could <I>Deinonychus</I> and other dinosaurs have been only semi-gregarious, making kills but tolerating kin? This is a bit far fetched, but it does serve to remind me that behaviors exist on a continuum and nothing is an "either/or" choice.<BR/><BR/>Still, great work Zach; this will be a fine submission to the Boneyard.Laelapshttps://www.blogger.com/profile/00920782525196396058noreply@blogger.com
