Wooster’s Fossil of the Week: A bryozoan etching (Upper Ordovician of Indiana)
Another trace fossil of a sort this week. Above you see the dorsal valve exterior of a strophomenid brachiopod from the Upper Ordovician of southeastern Indiana. Across the surface is a network of grooves looking a bit like a spider … Continue reading
Wooster’s Fossil of the Week: A very thin coral from the Upper Ordovician of Indiana
What we have above is a heliolitid coral known as Protaraea richmondensis Foerste, 1909. It has completely encrusted a gastropod shell with its thin corallum. Stephanie Jarvis, a Wooster student at the time and now a graduate student at Southern … 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 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 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

CHARLOTTE, NORTH CAROLINA–The brave souls Jonah Novek (’13) above and Kit Price (’13) below were the first Wooster students to present their posters at the 2012 Geological Society of America meeting. Jonah worked in Estonia this past summer on Early … Continue reading

Wooster’s Fossil of the Week: a deformed brachiopod (Upper Ordovician of Indiana)
Kevin Silver (’13), a sharp-eyed paleontology student, found this odd brachiopod on our field trip earlier this month in southeastern Indiana. It comes from the Upper Ordovician (Katian) Whitewater Formation. Kevin correctly identified it as Vinlandostrophia acutilirata (Conrad, 1842), an … Continue reading
Wooster’s Fossils of the Week: a little sclerobiont community (Upper Ordovician of Indiana)
Last week the students of my Invertebrate Paleontology class found many excellent fossils in the Whitewater and Liberty Formations of southeastern Indiana. We will be featuring some of them in this space. I want to start with one of my … Continue reading
