Sharks appeared around the same time (-200MY) the solar system was last on this side of the galaxy. Crocodiles evolved when the solar system was almost (-95MY) on the other side of the galaxy. Dinosaurs ruled for 3/4 (179MY) of an entire orbit.
The solar system orbits the galaxy once every 250MY.

That’s. Wack.
There was a period of 60MY where trees just kinda fell over and laid there because nothing had evolved to eat them.
