Re: What faunas/formations were at the KT

The other part of the this question regards what other dinos around the world may have survived until the extinction event. There has been a request to illustrate famous faunas like the Velociraptor/ Protoceratops locals with the impending comet approaching. I know, its silly and those two lived too early, but I'd like to make educated assumptions about the species of dinosaurs and where they flourished without any evidence...ouch , it even hurt to write that sentence...

If i am not wrong the Willow Creek Formation from Northern Montana and Alberta represents another terrestrial formation containing the KT boundary...

Terrestrial ones? Not many. Some intertrappean bed or other somewhere in India; however the formation in the Nanxiong Basin in southern China is called; and to the north of the Hell Creek, there's the Lance and the
Scollard, AFAIK. That pretty much is it so far.

The Frenchman Formation of Saskatchewan also extends up and through the K/Pg. Note that at any given spot in the American West the boundary might
be within the Hell Creek or slightly above.

I do not believe a South American terrestrial latest Maastrichtian fauna yet identified. In Europe some (in France and in Transylvania) get close but not up to the end. David mentions the Nanxiong and the Intertrappean Beds of western India it may be that a K/Pg boundary layer could be found in the Amur Valley but at present I don't think it has been found. New Zealand has boundary terrestrial deposits, but only (s)crappy dinosaurian fossils (great plants, though). There are boundary deposits in Antarctica, but again no dinosaurian fauna that can be really characterized. I don't know if there are late Maastrichtian dinosaurs yet known from Africa or Australia. The dinosaurian-bearing units of Madagascar don't get quite
that young.
