What did Earth look like X million years ago?
Last week I was in the field digging dinosaurs in Montana, when one of the dig leaders mentioned there was no grass back then, just lots of ferns, because grass hadn't evolved yet.It kind of blew my mind that for most of dinosaurs, there was just a lot of leafs and ferns.Here's some pictures for context (https://imgur.com/a/rE5wwc4), when you're out where most dino bones are found, you forget that it may have been a lush landscape of riverbeds approaching the ocean coastline, or that it may have been a dry arid desert landscape like in the land before time movies. Regardless, it's odd to imagine all of it, with no grass.
