Crinoid success
MITZPE RAMON, ISRAEL–One of our missions on this expedition to Israel is to find more and better examples of a distinctive crinoid in the Middle Jurassic Matmor Formation. Crinoids are stemmed echinoderms with a very long geological history, dating back … Continue reading
First field day: Makhtesh Gadol (A large bowl of geological delights)
MITZPE RAMON, ISRAEL–Today Will Cary, Yoav Avni (our friend from the Geological Survey of Israel) and I worked in the northern end of Makhtesh Gadol (“the large crater”). This geomorphic feature looks a bit like an oblong impact crater, but … Continue reading
Wooster’s Fossil of the Week: A scleractinian coral (Middle Jurassic of Israel)
In advance of my next field trip to Israel (watch this space!), our highlighted fossil this week is the scleractinian coral Microsolena, a genus named by the French naturalist Jean Vincent Félix Lamouroux in 1821. The specimen above was collected … Continue reading
Wooster’s “Fossil” of the Week: The most famous pseudofossil ever (Proterozoic of Canada)
This week’s specimen is a piece of obscure paleontological history, although it represents a “fossil” that was for a short time one of the most prominent in the world. In 1864, the uber-geologist Charles Lyell claimed it was “one of … Continue reading

Wooster’s Fossils of the Week: Hyoliths (Middle Ordovician of Estonia)
The fossils above are about as simple as fossils can be. They are internal molds (sediment-fills) of conical shells that were made of the carbonate mineral aragonite. The aragonite shells dissolved away after death and burial, leaving the cemented sediment … Continue reading
Wooster’s Fossil of the Week: Oyster balls! (Middle Jurassic of Utah)
The technical term is ostreolith, but “oyster ball” is much more descriptive. These fossils are found by the thousands in the Carmel Formation (Middle Jurassic) in southwestern Utah. As far as I know, this is the only place they’ve ever … Continue reading
Paleoecological Reconstruction of the Menuha Formation (Upper Cretaceous, Santonian), Makhtesh Ramon Region, Southern Israel (Senior Independent Study Thesis by Andrew Retzler)
Editor’s note: Senior Independent Study (I.S.) is a year-long program at The College of Wooster in which each student completes a research project and thesis with a faculty mentor. We particularly enjoy I.S. in the Geology Department because there are … Continue reading
A Paleoenvironmental Analysis of the Zichor Formation in the Cretaceous of Southern Israel (Senior Independent Study Thesis by Micah Risacher)
Editor’s note: Senior Independent Study (I.S.) is a year-long program at The College of Wooster in which each student completes a research project and thesis with a faculty mentor. We particularly enjoy I.S. in the Geology Department because there are … Continue reading
Wooster’s Fossil of the Week: Reef-forming brachiopods (Middle Permian of southwestern Texas)
In my early days of teaching paleontology I had an enthusiastic trading program with colleagues around the country. I would supply fine fossils from the Upper Ordovician of southern Ohio for what I considered exotic specimens from elsewhere. In one … Continue reading
Bioerosion on oysters across the Cretaceous-Paleogene Boundary in Alabama and Mississippi (USA) (Senior Independent Study Thesis by Megan Innis)
Editor’s note: Senior Independent Study (I.S.) is a year-long program at The College of Wooster in which each student completes a research project and thesis with a faculty mentor. We particularly enjoy I.S. in the Geology Department because there are … Continue reading
