April 1, 2006 - Cretaceous Fossils, Lee Co, AL
Submitted by Vicki Lais on Tue, 04/04/2006 - 22:00.
This Cretaceous site is slated to become a subdivision in the near future, so a dig to excavate and conserve material from the best layers was organized and coordinated by Patrick Sean Bingham, a grad student at Auburn University. Patrick's thesis topic is “Stratigraphic and Paleoenvironmental Context of the Ingersoll shale, an Upper Cretaceous Conservation Lagerstätte, Eutaw Formation, Eastern Alabama”. Another grad student from Auburn University, Terry Knight, was also working on his thesis, “Exceptionally Preserved Soft-Bodied Fossils of the Ingersoll shale, an Upper Cretaceous Konservat-Lagerstätte in the Eutaw Formation of East-central Alabama".
Many well known professionals from around the country volunteered their time and expertise to assist on the dig, including Dr. David Grimaldi and Collections Manager Carl Mehling from the American Museum of Natural History in New York City. Dr. Grimaldi was especially interested in the nice specimens of amber found at the site. Others who provided assistance and knowledge were Dr. Chuck Savrda and Dr. Ron Lewis, both from Auburn University, Dr. Bill Bevil from the Fernbank Museum of Natural History, Atlanta, Ga, and Dr. Bill Frazier, Dr. David Schwimmer and Dr. Dent Williams, all from Columbus State University, Columbus, GA.
It was a real treat to work with these professionals and others who participated in the dig, and everyone got “down and dirty”, quite literally, as various plant leaf and stem impressions, some actual leaves, fish scale impressions, and even pieces of amber were unearthed!

An overview of the dig location. Several feet of overburden was removed prior to the manual digging with picks and shovels.

Overview of the site. Material was placed in the large tubs and taken back for research. Note the orange spikes on the far right - the site was gridded, and one layer was designated "the middle", so some of the material is "above" or "below" that layer.
Nice Cretaceous leaf impression.
BPS members observe the dig operation and look through the discard pile for samples to collect. Later in the day, we were allowed to help load tubs and Greg assisted with the excavation.
Terry Knight is keeping a log of the geologic layers.

Humm . . . . did we miss any?? Better check those rocks carefully! Left to right - Vicki Lais, Bill Montante in back, Carl Mehling in black in front, Dr. Chuck Savrda, Dr. Bill Frazier, Terry Knight, Amanda Savrda.

Nice fossil, one can see scales using a magnifying glass.
Nice mussel.
This nice fossil was quite long, more was exposed as the overburden was removed.
Dr. John Interlandi is applying a fixative to the fossil to help preserve it. This clay material is damp when excavated, but the hot sun dries it out quickly. When it dries, the exposed surfaces crack and curl up like dried mud, destroying any fossil that might be there.
Nice exposure of leaf material.
Another plant fossil.
Nice leaves.
This is an extension of the long stem shown several pictures above.
Amber found at the site.
Seeds found at the site.
An actual leaf was preserved in the soft clay, note the curled up edge.
On a gray, overcast day that began with morning drizzle in Birmingham, and an unscheduled side trip to Georgia (don't ask), several BPS members participated in a paleontological salvage operation in Lee county, Alabama. When the sun came out full force later in the day, it made us appreciate the cloud cover!
