Wooster’s Fossil of the Week: A new crinoid genus from the Silurian of Estonia
It is my pleasure to introduce a new Silurian crinoid genus and species: Velocrinus coniculus Ausich, Wilson & Vinn, 2015. The image above is a CD-interray lateral view of the calyx (or head), with the small anal plate in the … Continue reading
Wooster’s Fossil of the Week: A stromatoporoid from the Silurian of Estonia
Stromatoporoids are extinct sponges that formed thick, laminated skeletons of calcite. They can be very common in Silurian and Devonian carbonate units, sometimes forming extensive reefs. The stromatoporoid above is Densastroma pexisum (Yavorsky, 1929) collected from the Mustjala Member of … Continue reading
Wooster’s Fossils of the Week: A trace fossil from the Ordovician of Estonia
The fossils above have been in a previous post as examples of hyolith internal molds from the Middle Ordovician of northern Estonia. I collected them on my first visit to the Baltic countries in 2006. This week I want to … Continue reading
Wooster’s Fossils of the Week: Embedded cornulitids from the Lower Silurian of Estonia
At first specimen this looks like a series of holes drilled into a small, smooth substrate (like Trypanites), but then you notice that the substrate has grown up around the holes, and on the far left you can make out … Continue reading
Stratigraphy and paleoenvironments of the Soeginina Beds (Paadla Formation, Lower Ludlow, Upper Silurian) on Saaremaa Island, Estonia (Senior Independent Study Thesis by Richa Ekka)
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
The first Wooster Geology student posters at GSA 2012
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 Fossils of the Week: Giant ostracods (Silurian of Estonia)
During our Estonian expedition this summer, Richa Ekka (’13) chose as her Independent Study project focus the Soeginina Beds (lowermost Ludlow, Upper Silurian) of the Paadla Formation exposed in southeastern Saaremaa Island. These carbonate sediments, mostly dolomitized, were deposited in … Continue reading
Wooster’s Fossil of the Week: a twisted little crinoid (Lower Silurian of Estonia)
This week’s fossil is a tiny little crinoid with an odd shape. Calceocrinus balticensis (shown above with the scale bar as one millimeter) is a new species from the Lower Silurian (Llandovery) of Hiiumaa, western Estonia. It is part of … Continue reading
Wooster’s Fossils of the Week: A stromatoporoid-stromatolite combination (Upper Silurian of Saaremaa Island, Silurian)
There are two common fossil types that begin with “strom” and look roughly alike to the untrained eye. One is the stromatoporoid, which is a calcareous sponge, and the other is the stromatolite, which is a layered structure produced by … Continue reading
Analysis of a Rhuddanian (Llandovery, Lower Silurian) sclerobiont community in the Hilliste Formation on Hiiumaa Island, Estonia: a hard substrate-dwelling recovery fauna — An abstract submitted to the Geological Society of America for the 2012 annual meeting
Editor’s note: The Wooster Geologists in Estonia this summer wrote abstracts for posters at the Geological Society of America Annual Meeting in Charlotte, North Carolina, this November. The following is from student guest blogger Jonah Novek in the format required … Continue reading
