Low Tech Blastoids Hi Tech Analysis

Our program this month will be presented by Dr. Jennifer Bauer. Her talk is entitled, Globetrotting with the Blastoid Brigade. The talk will provide an overview of Jen's dissertation work and other projects relating to understanding and examining blastoids from hand samples to using particle accelerators.

Dr. Bauer received her BS fromthe University of Illinois at Chicago in Biological Sciences, herMS fromOhio University in Geological Sciences, and her PhD from the University of Tennessee. Jen joined the Dry Dredgers in 2012 while working on her MS with Alycia Stigall on the Ordovician brachiopod, Eochonetes. She then switched clades to focus on understanding the complex morphology of blastoid hydrospires for her PhD with Professor Colin Sumrall. Jen spent a year at the Florida Museum working with Professor Bruce MacFadden and the FOSSIL Project before moving on to her current position as a Research Museum Collection Manager at the University of Michigan Museum of Paleontology. Here she cares for 2 million invertebrate and microfossil specimens. In this role, she is continuing her research on fossil echinoderms with a focus on understanding the anatomy and early evolution of blastozoans while mentoring students in collection management and digitization procedures.

Jen has been a recipient of three of the Dry Dredgers Paleontological Research Awards – one for her MS work and two while working on her PhD. She last presented a program to the Dry Dredgers in April of 2014 during her MS work on brachiopods.

The April 2021 Beginner’s Class will be via Zoom from 7:00 PM to 8:00 PM on April 23rd. It will be held before the general meeting. This month's class will be presented by Cameron Muskelly. The title of his presentation is, Dinosaur Discoveries of the Eastern US. He will be talking about various dinosaur finds from four states in the eastern US: Alabama, Georgia, North Carolina, and Mississippi.

Cam is 22 years old and a paleontology/geology educator in Georgia. He has always had a passion for dinosaurs and that has developed into chasing his one true goal in life of becoming a Paleontologist. Cam studies fossils from the Southeastern US as well as fossils from his home state of Georgia. He is a recent winner of the 2020 Katherine Palmer Award that was presented by the Paleontological Research Institute in Ithaca, New York.

This class will be managed through the Zoom Breakout Room feature.Once you have joined the generalmeeting(usingthe linkprovided by Jack Kallmeyer on the 22nd) you will need to locate the Breakout Room icon at the bottom of your screen and click it.

April Field Trip: The “Grand Tour” – from Ashland to Alexandria
by Bob Bross

In 1977,NASA launched two unmanned spacecraft to explore the outer reaches of our solar system: in launch order, Voyager 2 and Voyager 1. Titled “The Grand Tour”, Voyager 1 obtained detailed and close-up information during its flyby of Jupiter and Saturn; with that success, Voyager 2 was set on a wider course past those two planets, enabling it to go past Uranus and Neptune. These missions provided snapshots during each brief planetary encounter, furthering our knowledge of the outer reaches of our solar system; in fact, both spacecraft continue to send data well past the orbit of Pluto.  

On Saturday, April 24th at 10AMthe Dry Dredgers will do our own in person “Grand Tour” along our favorite Northern Kentucky scenic byway. Our launch point will be a shopping center parking lot, where mission details will be distributed to highlight each planned stop.

There are multiple road cuts along the Highway, ranging from the Ordovician to the Silurian as the road undulates up and down. We are planning for three stops, but will have handouts detailing other locations along the route. All locations will be on the right (South) side of the road, and will have sufficient shoulder areas to park alongside.

Caution: as this is an active highway, we ask that you use extreme caution when entering/exiting your vehicle. If you have young children, please ensure their safety by keeping them close to the road cut itself. The trip sites will not be steep, so the risk of falling rock is low; however, if you are working on an upper part, be aware of those below you. Please meet at the shopping center first, so we can conduct this Grand Tour together.

This field trip is limited to dues-paying members of the Dry Dredgers at this time to limit exposure to the Coronavirus. Social Distancing rules and face masks when needed are advised.
