The Richmondian Invaders

Our featured speaker this month will be Adriane Lam from Ohio University. Her program is entitled, “Paleobiogeographic analyses of Late Ordovician faunal migrations: assessing regional and continental pathways and mechanisms." Adriane has attended a number of our meetings and is another winner of the Dry Dredgers Paleontological Research Award that helped fund her work on this project. This topic is important to the Dry Dredgers as the Richmond invasion provides us with the most abundant fossils In the Cincinnatian.

Adriane is from Beaverdam, Virginia and received her undergraduate in geology at James Madison University in Harrisonburg, VA. While at JMU, she worked with a sediment core and identified planktic foraminifera species as well as ran isotope analyses to interpret paleoclimate changes across the Pleistocene to Holocene transition in the Gulf of Mexico. This project cemented her love for paleontology and paleoclimatology, and thus she applied to work with Dr. Alycia Stigall at Ohio University for her MS working in the Late Ordovician on invasion dynamics. Adriane’s thesis focuses on interpreting dispersal paths used by Late Ordovician taxa during the Richmondian Invasion interval, and the paleoceanographic and paleoclimate factors that facilitated a mass faunal migration.

Beginner's Class
by Greg Courtney

The Beginner’s Class meets at 7:15 PM Friday, March 27, in room 301 Braunstein Hall, one floor up from the regular meeting room. This month will feature Vice President Rich Fuchs who will do a presentation on graptolites. If you want to see Rich get on his soap box, ask him about the tube dwelling worm’s holdfast, Sphenothallus!

2015 Field Trip Season Is Here!
By Bob Bross

There are few things in life which are guaranteed – but our first official field trip of 2015 is one of those! On Saturday, March 28th, at 10:00 a.m. we will be visiting a great road cut Southeast Indiana. For those of you who have been there in the past, numerous finds will be there for the looking (and taking). Having said that, it is important you surface collect only; do not dig or remove large slabs, as this is frowned upon by state officials.

What might be found there? This site features a nice butter layer in the Liberty formation, and the associated trilobites for the persistent explorer. There are a wide variety of brachiopods, bryozoan, crinoids, the occasional conularia, horn coral, cephalopods, gastropods, and many other types of fossils – pretty much a great collection of Ordovician specimens for all.

Access to the terraced levels is best made from the upper (southern) end; pick a level, and then walk out along it. Climbing directly from one level to another is very hazardous and not recommended at all. As mentioned, since the levels can be accessed from the South end, there are plenty of items to be found without climbing. Younger and less mobile members will find plenty of fossils with very little effort.

We will meet on the site. Directions are published in the full Bulletin that is mailed and Emailed to members.  However, this field trip is open to non-members as well. So if you'd like to join us, email Bill Heimbrock at If you'd like to become a member, print and mail your dues with the application form.

Field trips are rain or shine. Yes it did rain last year, but we still had a great turnout. See you there!

April Auction
by Jack Kallmeyer

Tom Bantel and I worked on the Stocker library collection to prepare for the April auction. We have about 100 lots of books. As a matter of fact, the collection was so large, we are only able to offer half of it this year and will have the remainder for next year’s auction. We’ll add fossils from the Stocker collection next and your donations brought in the night of the auction. The collection contains books useful to the beginner as well as the advanced collector. We’ll publish a complete list in the April electronic bulletin. Fossils from this collection include many from sites no longer accessible to collectors.

More interesting articles are found each month in the Bulletin Emailed to members of the Dry Dredgers. Click here to join.

The password to the members-only area of can be found in the full-version of the bulletin emailed and snail-mailed to paid-up members. Another great reason to join!
