As a fan of both paleontology and astronomy (and a lot of other things), sometimes I find myself pondering the fact that quite a few astronomical events happened during the history of life on Earth. Such as the lunar impact that caused the Tycho crater, estimated to be about 100 million years old, which would place it in the middle of the Cretaceous. So dinosaurs could have seen the impact happen if they had been paying attention. I wonder if they would have noticed?
Given the date, I couldn't help but plug the mid-Cretaceous Wayan Formation yet again, so here's an Oryctodromeus having a snack and totally ignoring what's happening to the Moon.
I based the color scheme and time of day on a lovely photo I took a while back of the Moon rising above the mountains near my neighborhood one late afternoon.
