But if dino-scientists could, maybe this is why humans occasionally found low-production fields?
Look, it's not dino-surgery. Before the dinosaurs lived, for millions of years plants and plankton and wiggly things lived and died in huge mosh pits at the worlds largest rock concert. Shoggoth and Ktulu were the biggest act back then. Old news by the time the dinosaurs came about, of course. I mean who listens to Elder Metal these days? Anywho, a terrible accident happened when the massive stack of Marshall amps fell over, crushing the audience. Nobody cleaned it up, in order to honor their memory. Fast forward to the Jurasik period and they discovered oil! Soon dinosociety was zipping around on scooters and polluting the air with their jacked up monster trucks. The sky got so dark from soot it blocked out the sun. Then it got cooler, and well, you can imagine the rest.
