Wooster’s Pseudofossil of the Week: Manganese dendrites from Germany
We haven’t had a pseudofossil in this space for awhile. A pseudofossil is an object that is often mistaken for a fossil but is actually inorganic. The above may look like fossil fern, but it is instead a set of … Continue reading

Wooster’s Fossil of the Week: A glass sponge from the Upper Ordovician of southern Ohio
Like all those who teach, I learn plenty from my students, sometimes with a simple question. Richa Ekka (’13) asked me last semester during a paleontology lab if the above specimen was really a trace fossil as I had labeled … Continue reading
Wooster’s Fossil of the Week: A conulariid from the Upper Ordovician of Indiana
This week’s fossil is not technically impressive: it is a rather modestly preserved conulariid from the Waynesville Formation of southern Indiana (location C/W-111). It is notable because it is one of the very few conulariids I’ve found in the Ordovician, … Continue reading

Wooster’s Fossils of the Week: Episkeletozoans from the Middle Jurassic of Israel
Last week I had a delightful research afternoon with my former student Lisa Park Boush, now a professor in the Department of Geology and Environmental Science at The University of Akron, and currently Program Director, National Science Foundation, Sedimentary Geology … Continue reading
Wooster’s Fossil of the Week: A swimming clam from the Pliocene of Cyprus
In the summer of 1996, I was a co-director of a Keck Geology Consortium project in Cyprus. One of my students was Steve Dornbos (’97), now a professor at the University of Wisconsin, Milwaukee. We had a great time exploring the Nicosia … Continue reading
Wooster’s Fossil of the Week: A bivalve boring from the Upper Ordovician of southern Ohio
This week’s fossil is from close to home. In fact, it sit in my office. The above is a trace fossil named Petroxestes pera. It was produced on a carbonate hardground by a mytilacean bivalve known as Modiolopsis (shown below). … Continue reading
Wooster’s Fossil of the Week: A horn coral from the Upper Ordovician of Indiana
This week’s fossil is a very common one from the Whitewater Formation (Richmondian, Upper Ordovician) exposed near Richmond, Indiana. It was collected, along with hundreds of other specimens, during one of many Invertebrate Paleontology field trips to an outcrop along … Continue reading
Wooster’s Fossils of the Week: Shark teeth! (Upper Cretaceous of Israel)
This week’s set of exquisite fossils is presented in honor of Andrew Retzler (’11) who has just had his Senior Independent Study thesis at Wooster published in the journal Cretaceous Research: “Chondrichthyans from the Menuha Formation (Late Cretaceous: Santonian–Early Campanian) … Continue reading

Wooster’s Fossil of the Week: A gumdrop bryozoan (Middle Ordovician of eastern Iowa)
This simple, rounded fossil with tiny holes on its surface is the trepostome bryozoan Prasopora falesi (James, 1884) from the Middle Ordovician Galena Group of eastern Iowa. It was collected with dozens of others on an Independent Study field trip … Continue reading
Wooster’s Fossil of the Week: A crab from the Pleistocene of northern Australia
Isn’t this amazing preservation? This fossil crab, which we received as a donation a few years ago, is Macrophthalmus latreillei (Desmarest, 1822) from the Pleistocene of northern Australia. It is virtually identical to its modern counterpart of the same species, … Continue reading
