Hi All, I took a trip (I live just outside of Philly) down to Calvert Cliffs on the MD side to spend a couple days hunting. I was able to visit the VA side of the Calvert Formation back on Labor day, and was excited to see the MD cliffs. First day I spent all of my time at Matoaka Beach hunting solo. Tried to access another section of beach later that day, however it required hiking through some thick vegetation, and I was losing light, so I gave up. Second day I met up with the Delaware Valley Paleontology Society to visit a few sites with CHAPTours. Wound up visiting 3 different beaches, and finished off back at Matoaka (I didn't know we'd be going here otherwise I'd have picked a different beach the first day). Overall, I had pretty good outings both days. Surprisingly I didn't find a single shark tooth, but lots of amazingly preserved bivalves and gastropods. Some photos from the beach/cliffs from both days. From the top of the cliffs: Bivalve fossils were everywhere. Group shot with a sampling of finds.

Calvert Formation - Stratford Hall and Westmoreland State Park
Masonk posted a topic in Fossil Hunting Trips
Hi All, I thought I would share photos of a recent trip to Virginia over Labor Day weekend. We stayed in Colonial Beach, and had quick access to Stratford Hall and Westmoreland State Park. I was able to squeeze in 3 visits during the trip, once with the family, and twice solo. Friday 9/1 - Stratford Hall Had a late start, but the beach wasn't too crowded. Had the whole family in tow. My wife found a nice posterior Megalodon tooth and my daughter landed a a good looking Physogaleus tooth. I was happy to snag a complete tooth from a Odontocete. A woman with her son on the beach found a beautiful, complete Cow shark tooth. Was my mission to find a complete one, but only found a couple pieces. View of the cliffs from the beach. Area beneath the cliffs was off limits. Group shot of our finds from the day Some close-ups of the different fossils: Galeocerdo sp. (Tiger Shark)- This one washed up on the shore next to me while I was crouched, talking with my wife. Odontocete tooth Coprolite? or slag?- 19 replies

Spent about 2 hours surface collecting this morning, tides were not favorable but was still able to find some decent teeth including what I believe is either a partial dolphin or porpoise tooth. I thought that I had found a partial benedini, however it appears that it may just be a large partial curved mako tooth.

Ok. Found this one in the Potomac River near Westmoreland State Park / Fossil Beach. It has some enamel toward the narrow end and in the hole. Never seen anything like it and would love some ID help.

I found this near Westmoreland State Park in the Potomac. It seems too well preserved to be a fossil. Clearly a vert, but from what?

Is this an odontoid-dens (odontoid process/peg) from a fossil C2 axis whale vertebrae
fossilnut posted a topic in General Fossil Discussion
In with a number of whale vertebrae that were provided for me to do a talk on "Whale Evolution", I found two "unusual structures". My searches led me to believe that each of these were separated parts of the C2 axis vertebra namely an odontoid-dens that projected through the C1 atlas vertebrae to help with the rotation of the head. I was not able to find any pictures of this structure in any pictures of fossil whale axis vertebra online-I do not have access to professional papers. I did find pictures of modern whale axis C2 vertebrae with this structure. Can anyone confirm this identification or provide other suggestions? The 2 middle pictures below are of the fossils I am trying to ID.- 3 replies

Beach hunters - what do you do while waiting for the tide to go out?
Mara_Masina posted a topic in Questions & Answers
Hunting log, 12/11/21. It is 9:28am. I've been here since 7am. High tide blessed me with five teeth, one small and four medium. The beach is quiet. The tide is high. Low tide isn't until 3. Wishing I'd brought caffeine. Tempted to move some driftwood for a napping spot. What do you guys usually do until low tide?- 17 replies

A friend of mine found this bone a little south of Calvert Cliffs state park. Is there any way to tell if it was a land or aquatic mammal?

I often find these items south of calvert cliffs, but not grouped together. Could they be sea urchin spines or is it some sort of plant?

It has been a bit since I have done a post. It has been over a year since I have been out hunting. I am days away for things to open up for me.... finally. I am ready to just live in a creek and look for fossils for weeks. I have been lucky to pass the time over the year looking through matrix from different locations. I was very fortunate and extemely thankful to receive some matrix from @sharkdoctor. These two squalus teeth are from matrix in Calvert Formation in central Virginia. Each of them are just a tad over 1mm. Found this one last week Just found this one tonight

As I’ve mentioned in other posts, we got quite a bit of matrix from @sharkdoctor recently. Much of what he sent was from the Calvert Formation. Most of what we found was fairly easy to identify as Aaron provided the guide for the Calvert. When I got the very end of the bag from lag site 210, I found a couple of teeth that I could not match to those in the guide. They appear to me to be Catshark but of a different morphology than those in the guide and quite a bit different from those I had found. They are a bit larger than the other Catsharks I found and overall seem to look more like Pachyscyllium teeth. Unfortunately none are complete but there was one that is I think is complete enough to perhaps ID. I am going to send Aaron these pictures and they may get forwarded to the CMM but in the meantime I wanted to see if I am way off base in my thinking. Any and all opinions are welcome. First tooth is the most complete and largest at 3mm .

We were very fortunate to get quite a bit of Calvert Formation micro matrix and some great teeth from @sharkdoctor. This is my first exploration of this formation and I am loving it. Lots of Carcharhiniformes material and it will take me a little time to ID some of Carcharhinus teeth but that is a good learning experience. I need the practice. The very fine matrix has been my favorite. I’ve found a few Scyliorhinus teeth, a few Squalus teeth and a few Mustelus teeth. Raja teeth are way more common than in STH. I’ve searched a lot of STH matrix and found 2 Skate teeth. It took me 10 minutes to find two in this mix. I have a lot more searching to do but I am really enjoying this.

I think I saw this tooth form in an identification book at some point and laughed at it. It's such a weird tooth. However, I can't find the reference now. It's driving me crazy. Any ideas what this is? It is possible that the tooth was reworked from an earlier formation (Old Church or Piney Point). From the Calvert Formation, bed 3. The scale box=5mm. Lingual surface? Labial surface? @jcbshark @MarcoSr @Al Dente @Gizmo @fossilsonwheels

I was going through my collection and found this tooth in with my Carcharias (Sand Tiger) teeth from Bayfront Park, Calvert Cliffs (Miocene). It doesn't resemble the others and I wondered if it might be something else. It is 7/8 of an inch tall. Thanks.

Hi everyone! This is my first post here on the forum in what feels like forever. I'd like to be active here again, and thought there was no better way to kick it off than showcasing my meg tooth! Some of you may have already seen the tooth on my Instagram, Facebook, or YouTube, but I wanted to make a post on here as well. I found the tooth last week along Calvert Cliffs. It's approximately 4.1" slant height and in near perfect condition. It even has that iconic Calvert Blue color on the crown that I love so much! I've been dreaming about finding a tooth like this ever since I started collecting a few years ago, and my dream has finally come true! Check out the pictures below and the YouTube video if you'd like to see how I found it. Hopefully the first of many great finds this year!
