Glad to see more info out...Wonderful info, Thanks.<br /><br />Glad to see more info out on the Triassic. I hope more attention is paid to S W Carey's two expansion events 50 million years apart. That fits the two great extinction events. <br />Even NASA now admits we are under compression but identifies it with an unfound gravity wave: flat and long. <br />If these compression events are regular and periodic (perhaps from a local like Proxima Centauri) the extra energy that produce compression events which move the heliosphere in close to Mercury can be from the galactic center? <br />Just read from a previous blog that the Gobi is green in the spring from chives.

Fascinating blogging and very informative.

I was originally thinking something like one of the standard mammaliforms, but your essay persuaded me to go with an advanced dicynodont.<BR/><BR/>Scenario: A dicynodont genus survives up to and a bit beyond the KT boundary. It's a small animal, herbivorous, with an elongated muzzle, prominent ears, and a diastema between beak and molars. A few species are horned, though those are not ancestral to the modern unicorn.<BR/><BR/>The rise of the grasses means the end of the last of the true ceratopsians (no asteroid impact, the K/T boundary is set thanks to the Deccan Traps, and so the extinction of the non-avian dinosaurs is more drawn out and certain groups survive to the present day). In any case, these late dicynodonts are able to take advantage of the new grasslands, much as a group of mammals is, and in due time a one-horned, one-toed, horse-sized mammaliform animal appears, and is domesticated and comes to serve much as the horse does.<BR/><BR/>But not entirely as the horse does, having a few traits that means it can't be treated or used exactly like a horse. Unicorns not being as efficient in drayage, somewhat wilder in temperament, and requiring special treatment during pregnancy and a more restrictive diet.<BR/><BR/>And my decision to make them highly evolved dicynodonts is all because of you. :)mythusmagehttps://www.blogger.com/profile/10458869083534878283noreply@blogger.comtag:blogger.com,1999:blog-10092066.post-3850362121940930702008-03-26T17:05:00.000-07:002008-03-26T17:05:00.000-07:00They also weren't very largeuh.

I've actually got a fairly good working model, but I just don't know what to do with the hindlimbs.<BR/><BR/>I'm doubting that dicynodonts were warm-blooded, just because of their inefficient chewing mechanism and sprawling gait. They also weren't very large (I think the largest was the size of a cow, actually).<BR/><BR/>There is a lot more I'd like to know about the group though (I'm sure we all would). Very strange critters, with some of the wierdest skulls around!Zachhttps://www.blogger.com/profile/08692080707969333711noreply@blogger.com
