Wet and Cold Wooster Geologists in the Silurian of Central Ohio
DAYTON, OHIO–It was 37°F and raining this morning as three stalwart Wooster Geology students and I worked in a muddy quarry near Fairborn, Ohio (N 39.81472°, W 83.99471°). Our task was to scout out a beautiful exposure of the Brassfield … Continue reading
Wooster’s Fossil of the Week: A scale tree root in its own soil (Upper Carboniferous of Ohio)
Last week a local man, Larry Stauffer, brought in the above fossil for identification and then kindly donated it to the department. It is part of the root system of Lepidodendron, the “scale tree” of the Carboniferous Period. What is … Continue reading
A Drool-Worthy College Museum
AMHERST, MA – Last weekend, some Wooster Geologists attended the Keck Symposium at Amherst College and were awed by their geology museum. The Beneski Museum of Natural History is housed in a modern building and covers three floors, displaying over 1,700 specimens. The museum … 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 spiriferinid brachiopod (Logan Formation, Lower Carboniferous, Ohio)
This brachiopod is one of the most common in the Logan Formation of Wooster, Ohio, so our students know it well from outcrops in Spangler Park and the occasional excavations in town. Four specimens of Syringothyris Winchell 1863 are visible … Continue reading
Wooster’s Fossils of the Week: Three cobble-dwelling oysters from the Upper Cretaceous of southern Israel
These fossils of the week, three well-worn cemented oysters, are highlighted to celebrate the final acceptance this past week of a manuscript that describes their geological setting and significance: Wilson et al., 2012 (see reference below). They are attached to … 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 windy, windy day in the Cretaceous
MITZPE RAMON, ISRAEL–Melissa and I finished our work in the Jurassic of Makhtesh Gadol yesterday, so today we went out with Yoav to explore the Upper Cretaceous and Eocene exposures just a few kilometers north of Mitzpe Ramon. This is … 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
