Today we surface collected from a new site that a member of the crew found on an evening prospecting trip a few days ago. Now a barren wasteland, it once represented a place where the Cretaceous river flooded its bank, spilling sediment and bone across the surface. It’s quite a lengthy layer of bone, around 50 meters long and it took half a day to get a grid set up, particularly around the huge sandstone boulders peppering the hills.
We collected the bone from the surface and dug a few test pits to evaluate the quality of bone and the types of animals preserved. But honestly it’s been brutally hot here the past few days with heat indices around 113. And if you think the air temperature is high you should talk to one of the undergraduate students who commented today that the ground was too hot to sit on (well he actually put it in a different way…). Later when I put our acetone-based consolidants on some sediment surrounding a fossil bone it boiled on contact. Folks… the boiling point of acetone is around 133 degrees. So yeah, with surface temps somewhere near 130 today, I guess we did boil in the quarry. Quite literally.
