@strangetruther (nice name) ...Thanks for comments.<br /><br />@strangetruther (nice name) I don't know I just stole the pic off of wikipedia it looks fine to me...<br /><br />@BrianL The idea of giant multi ton wading fisheaters in the Mesozoic has largely been accepted - spinosaurids. There are no multi-ton wading predators around today or even anything approaching that size. Why could there not have been multi-ton dabblers around in the Mesozoic as well? If you look at the sheer biomass of huge flocks of dabbling waterfowl around today I think it opens the door to thinking about large dabblers if the conditions allowed. I suggest Azolla aquatic fern as a potential food supporting such animals.<br /><br />As for the seeming lack of other dabblers maybe we need to consider the possibility that we are misinterpreting them. You mentioned Nigersaurus and broad-mouthed duckbills, maybe they were grazers but did a bit of dabbling as well? ... like many geese/ducks do both grazing and aquatic foraging/dabbling. I remember a paper a while back suggest some ornithomimids had keratinous lamellae indicating potential dabbling. Maybe some slack jawed weak toothed ankylosaurs slurped up algae/aquatic plants on the regular? My point is there may in fact be more - we are just not seeing them because we are looking through the lens of modern ecosystems where all large animals are well behaved mammalian herbivores. And dabblers are relatively smaller. <br /><br />And in the case of the Nemegt in the post I went over the environment which closely approximates it- the Okavango delta- a seasonally flooded inland basin with no outflow. Perfect for a dabbler. I should stipulate that dabbling need not exclude other methods of foraging for terrestrial plants, fruit, bulbs, etc etc. <br /><br />But we still have to wait and see what the skull publication tells us. Are there any signs of lamellae, was the bite powerful or weak?<br />Duane Nashhttps://www.blogger.com/profile/14467779935085970909noreply@blogger.comtag:blogger.com,1999:blog-8161161431451849208.post-37733212866309402502014-06-04T08:33:16.930-07:002014-06-04T08:33:16.930-07:00Is it me or are those ornithomimosaurs (including ...Is it me or are those ornithomimosaurs (including Big D.) naked or only very very sparsely covered in fuzz?<br /><br />As for *Deinocheirus* being a 'dabbler', I'm not sold on that though mostly for practical reasons. How big would their oasis or 'oasis' have to be to support a yearlong population of these beasts? Also, taking Mesozoic balminess into consideration, one would expect there to have been other creatures like this around during so long a time period, wouldn't we? This is negative evidence, but we simply do not know of any 'dabblers' this size, much less non-volant ones.<br />If we just look at size and anatomy, surely large and broadmouthed hadrosaurs and the likes of *Nigersaurus* are the best analogy around for *Deinocheirus*?<br />That being said, I do enjoy your out of the box thinking as usual. Would you happen to have an explanation for why all these huge coelurosaurs (except giant tyrannosauroids) are exclusively Asian?BrianLhttps://www.blogger.com/profile/17880867575515761505noreply@blogger.comtag:blogger.com,1999:blog-8161161431451849208.post-78196746123191905342014-06-04T06:52:28.826-07:002014-06-04T06:52:28.826-07:00Hi!

This can be minimised by slightly blurring photos before reducing them in size.strangetrutherhttps://www.blogger.com/profile/06608525362496458458noreply@blogger.com
