Wooster’s Fossils of the Week: Wiggly little foraminiferans from the Middle Jurassic of southern England
These shell fragments are of the oyster Praeexogyra hebridica var. elongata, and I picked them up long ago from a remarkable unit made almost entirely of them. It is the Elongata Bed at the base of the Frome Clay (Middle … Continue reading
Wooster’s Fossils of the Week: dinosaur gastroliths (Jurassic of Utah, USA)
These rounded stones are labeled in our collections as gastroliths (literally “stomach stones”) from Starr Springs near Hanksville, Wayne County, Utah. I’m featuring them this week in honor of our Utah Project team working right now in the baking Black … Continue reading

Wooster’s Fossils of the Week: A calcareous sponge with a crinoid holdfast (Matmor Formation, Middle Jurassic, Israel)
The Class Calcarea of the Phylum Porifera is a group of sponges characterized by spicular skeletons made of calcium carbonate (calcite in this case). The spicules (small elements of the skeleton) are often fused together, causing the sponges to look … Continue reading
Wooster’s Fossil of the Week: A curving scleractinian coral (Middle Jurassic of Israel)
Since Melissa Torma and I recently returned from our expedition to southern Israel (see immediately previous posts), I thought our weekly fossil highlight should be one of our specimens collected from the Middle Jurassic Matmor Formation of Makhtesh Gadol. This … Continue reading
A field day cut short by angry camels and a threat of rain … but at least the dust is gone!
MITZPE RAMON, ISRAEL–Compare the image above to the one taken in the same place two days ago. Much better! Our only dust today was a local product from the unending winds. The Saharan dust is gone. We paid for this … Continue reading
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 … Continue reading
Another dusty day of fieldwork in the makhtesh
MITZPE RAMON, ISRAEL–It was a little warmer today in Makhtesh Gadol, but the sun was still obscured by the dust blown across the southern Mediterranean from the Sahara Desert. I may have an innate tolerance for dust from my childhood … Continue reading
A dusty but successful start on field work in southern Israel
MITZPE RAMON, ISRAEL–Melissa Torma, our friend Yoav Avni (Geological Survey of Israel), and I just ended a productive first day in the field. The two of them are shown above in classic paleontological poses. They are collecting fossils from Subunit … Continue reading
Wooster Geologists in southern Israel for Spring Break fieldwork
It’s a low-light, iPad photo, but at least it shows Wooster geology junior Melissa Torma enjoying a fine meal in the Hotel Ramon of Mitzpe Ramon, deep in the Negev of Israel. We arrived here this afternoon after a 22-hour … Continue reading
Wooster’s Fossil of the Week: An ichthyosaur vertebra (Middle-Late Jurassic of Wyoming)
It’s only half a bone, but the above is one of my favorite fossils. This is a vertebra of an ichthyosaur, identifiable by its figure-8 cross-section. It is from the Sundance Formation (Middle-Late Jurassic) of Natrona County, Wyoming … and … Continue reading
