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.<p>It kind of blew my mind that for most of dinosaurs, there was just a lot of leafs and ferns.<p>Here's some pictures for context (<a href="https://imgur.com/a/rE5wwc4" rel="nofollow">https://imgur.com/a/rE5wwc4</a>), 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 <i>no grass</i>.
