Fall Equinox Calvert Cliffs Fossil Trip

I usually do a fossil set up at the Nanjemoy Heritage Festival each fall. It's a nice place to do a set up since it's close to some Potomac fossil hunting spots, as well as the Chesapeake Bay fossil spots. I usually make a weekend out of it, and fossil collect at a few locations.

This year I decided to try the Paleocene Aquia formation along the Potomac river, and then head to the Calvert Cliffs area for Miocene fossil shark teeth. Since most of the fossil spots are surrounded by private property, the best/only way to get to many of them is a boat.

The Paleocene Potomac:

Waves were hitting against the Paleocene Cliffs. The beach areas were far and few between.

After checking the tide charts, I decided to first go the Aquia formation and collect before the Nanjemoy festival began. Although I arrived at low tide, the area was mostly submerged. I often found myself in knee to waist deep water. Only a few tiny spots of beach were dotting the cliffs. As a result, I didn't find much in the way of fossil shark teeth. However, I managed to find a fragment of Indian pottery.

Below are the fossil found from the Aquia Formation:

After the disappointing trip to the Paleocene fossil spot, I set up at the festival and had lots of kids look through the reject material from the PCS Mine in Aurora, NC. (See the Aurora page). Once the festival was over, I packed up and headed to a campsite for the evening and weathered through a storm. The next morning, I launched the Jet Ski and headed toward the Miocene Calvert Formation to fossil hunt. This time the tides were MUCH better, as the water was low and there was plenty of beach and gravel to scour. All in all, the fossils were far and few between. This was expected as the cliffs get hit hard by fossil collectors nowadays. I did manage to find a 2 1/4" megalodon with damage to the tip, a pristine 1 7/8" mako that is razor sharp, a beautifully preserved crocodile tooth (it was only 1") , and a few big snaggletooth shark teeth. Overall, I didn't do too bad. It's been a few trips since I have found ANY megalodons, so even a small 2" class megalodon was nice to find.

Bald Eagles at play
We caught some female Bald Eagles at play. This was taken with a point and shoot camera, so the quality isn't too great!


Here's another picture of the Eagles. They seem to be getting more common in the Chesapeake Bay area.


This is a Southeastern Five-lined Skink (a.k.a. Eastern Five-striped Skink / Common Five-lined Skink ) clinging onto the Aquia formation. He's probably also thinking "Why is the water so high??"

This is the larger
This is the larger "Mako" shark tooth fossil as it was found at the Calvert Formation. It's actually a Cosmopolitodus hastalis tooth, a White Shark.
The sad part is although it is laying out in plain sight, we walked past it 3 full times before spotting it!!!

This is the Native American pottery fragment found along the banks of the Potomac River.
This is the Native American pottery fragment found along the banks of the Potomac River. This fragment, although small, is interesting in that they mixed the clay with crushed quartz to strengthen the pottery. Usually they harden it with sand.
