Here is a link to a paper describing a paleoenvironment dating to the Neo-Aptian of south-east Brazil. The authors liken it to death valley in California; an inland hot, dry basin with alluvial fans/salt lakes and nearby high lands. The dominant flora, inferred through palynology studies, is Classopolis (cheirolepediaceae) with lesser components of gnetales. Auraucariacites pollen is inferred to have blown in from nearby cooler, wetter highlands.

The plant fossil record, like the vertebrate fossil record, can suffer significant bias.
