Re: [dinosaur] Geological formations with the highest number of dinosaur species

[Mickey Mortimer <mickey_mortimer111@msn.com>]

Also only including named species isn't a realistic count of taxonomic diversity.  Basically every Campanian-Maastrichtian North American Formation has a dromaeosaurine, saurornitholestiine, troodontid, Paronychodon, Richardoerstesia gilmorei and R? isosceles equivalent for instance, but did this list include all five taxa for all of those formations?

Something worth noting, though, is that the species listed in a formation are not always contemporaries. Some of the best studied formations (like Horseshoe Canyon, Dinosaur Park, and Morrison) show a succession of faunal assemblages through their history. So the number of these which were actually living next to each other in time and space may be lower than these numbers reflect.

Good day!

Is there any kind of list of the "richest" geological formations with the highest number of known valid dinosaur genera/species? My guess is that the Dinosaur Park Fm. would be on top? Thank you very much, in advance! Tom
