It's not that grass didn't exist (there are grass seeds in some of the latest examples of fossilised dinosaur dung) just that grasslands as such were not yet widespread. Still, grass may not yet have fully adapted to drier environments itself, since it probably first evolved near rivers, so places that were dry, like the Tibetan Plateau, may just have been rather barren. But I confess to this being a little outside my expertise!JK Revellhttps://www.blogger.com/profile/00358838350092883422noreply@blogger.comtag:blogger.com,1999:blog-4209921721314660731.post-7147353893792318872023-03-19T20:19:33.246+00:002023-03-19T20:19:33.246+00:00Before grasslands, what sort of vegetation did you...Before grasslands, what sort of vegetation did you get in places too dry for forests?Andreas Johanssonhttps://www.blogger.com/profile/08802392912541974977noreply@blogger.com
