Dry Dredgers Field Trip
April 29, 2006
Brookville, Indiana
Arnheim, Waynesville and Liberty Formations, Late Ordovician Period
Corals
The most common coral found in good numbers that day was the horn coral, Grewingkia.
Another common horn coral found was this Streptelasma.
Here's an interesting specimen. It's a gastropod, completely encrusted with
the colonial coral Protaraea richmondensis.
A less common coral for this site, we found was this sample of the
colonial coral, Tetradium. On the next road cut down the road
(Brookville North), we collected car loads of this coral, though.
And there was at least one layer of phosphatic microfossil material on the
site. Shown below, the layer is exposed on this rock surface. Fun stuff with a
microscope!
That's it folks! Sorry it took so long to get it online, but I had so many
photos! Hope you enjoyed them.
Join us for our next field trip to a popular Northern Kentucky Kope Site!
