Wooster Geologists in Paleontological Heaven

MITZPE RAMON, ISRAEL–The above is an untouched view of an eroding marl of the Matmor Formation (Middle Jurassic) in Makhtesh Gadol. I simply placed a one shekel coin in the scene for scale. This is why we love this place — the fossils are just rolling out of the outcrops (once you know where to look). Our ultimate goal is to describe the communities in this particular unit, and you can see that we have rich material to work with. You can try to identify the fossils you see here. I’ll give the answers below!

Melissa walking across the northern end of Makhtesh Gadol through the middle part of the Matmor Formation. You can see in the distance that dust (and the wind that brought it) is still an issue.

Ready for the answers to the fossil quiz above? 1 = scleractinian coral; 2 = Apiocrinites (crinoid) calyx base; 3 = Apiocrinites calyx plate; 4 = terebratulid brachiopod; 5 = Apiocrinites stem fragment; 6 = echinoid spine; 7 = oyster; 8 = Apiocrinites calyx plate; 9 = another kind of oyster.

In a close-up yet another type of brachiopod is visible. The red circle shows a thecideide brachiopod (no doubt Moorellina negevensis) attached to a crinoid column.

Cool, eh? And this is just a taste of what we saw today. Heaven indeed.

    70 degrees, sunshine, and blue skies today. No dust storms for us!
