March 2018


The Dry Dredgers welcome Professor John M. Malinky as our featured speaker. Professor Malinky’s program is entitled, “Hyoliths: Mysterious Animals Of The Early Paleozoic.”

Dr. John Malinky, Ph.D. earned his Bachelor of Arts degree (1977) from Franklin & Marshall College, his Master of Science from Ohio University (1980) and his Doctor of Philosophy from the University of Iowa (1984). All degrees were awarded in geology. His specialty is paleontology, the study of ancient life. Dr. Malinky was a Collegiate Professor at the University of Maryland University College for fifteen years, teaching in Germany and several other sites in Europe. This is his eleventh year of teaching geology at San Diego City College and physical science at Palomar College, San Marcos, California. Dr. Malinky maintains on-going research programs at various institutions, including the University of Heidelberg (Germany), the Natural History Museum in Berlin, (Germany), the Paleontological Research Institute in Ithaca, N.Y., the Smithsonian Institution in Washington, D.C., the University of Tokyo Museum of Natural History in Japan and the Nanjing Institute of Geology and Palaeontology in China. He recently accepted a position as an editorial reviewer for the journal Palaeobiodiversity and Palaeoecology, published by the Senckenberg Museum in Frankfurt (Germany). He is the author of 54 articles on hyoliths, an extinct class of molluscs.

Beginner's Class
by Greg Courtney 

The Beginner’s Class will be held at 7:15 PM, Friday, March 23rd in room 301, one floor up from the regular meeting room. Rich Fuchs will give an introduction to trace fossils. He will explain what they are, what animals make them, what they look like and how to identify them. There will be photos and actual specimens shown.

March Field Trip
by Matthew Speights

Our first outdoor field trip of the season will be held on Saturday, March 24th, at 10:00 A.M. We’ll be collecting on a roadcut south of Flemingsburg, KY. It exposes the Corryville and Mount Auburn Members of the Upper Ordovician Grant Lake Formation. The roadcut was blasted between 2005 and 2006, so it hasn't been collected for very long. The very fossiliferous Corryville Member is exposed where we will meet. Like the slightly older Bellevue Member, the Corryville has plenty of Hebertella and Vinlandostrophia (= Platystrophia) ponderosa brachiopods to collect. The most interesting fossil here, though, is “Solenopora,” wrinkled lumps that are abundant, can be up to 6" across, and are often colored pink (which may be due to a boron-containing pigment). Although they appear somewhat like a stone brain (you can tell your friends that your brain is a bit fossilized…), “Solenopora” was probably a calcareous red algae that might have looked similar to rhodolithic coralline algae today. In 2004, the European type species of Solenopora was reclassified as a chaetetid sponge, so the specimens we will collect probably need a new genus name (that’s why we use the name with quotation marks).

There is plenty of parking at the site along the roadside on both sides; just be careful to pull off and park in a spot where you are clear of traffic and where there is not a steep dropoff. Be careful crossing the road if you park on the left (east) side.

Directions to where we will gather can be found in the full-Bulletin both mailed and emailed to dues-paying members. Non-members are welcome on this trip. Just email Bill Heimbrock at and he will get you what you need to attend the field trip.

You can find lots more interesting and informative articles in the full members' bulletin. Not a member? Join now. Here's how.
