Mussel Shells, Perna condensa Middle Miocene Choptank Formation Excavated from matrix submerged in the Chesapeake Bay, about 10 feet off of the beach at St. Leonard, MD, at low tide. Internal molds from a Miocene mussel bed, left in fine clay and stabilized with Paleobond to prevent disintegration© Heather JM Siple 2018

Collected loose on the beach in St. Leonard, Maryland middle Miocene Choptank Formation Drum Cliff Member Chesapectin nefrens is an index fossil for the Drum Cliff Member of the Choptank Formation, meaning that whatever chunk of matrix one may find fallen out of the cliffs, the precise layer is known so that other fossils in the same block can be identified. These are a very common find at St. Leonard and other places, but I particularly liked the coloration on this one!© Heather JM Siple 2018

Excavated from matrix in the Chesapeake Bay, about 10 feet off of the beach at low tide. View is external on both valves, but hard outer coating has been lost to decay. Valves are pearlescent.

Excavated from landslide material approximately 1/2 mile nw of Matoaka beach access. Found 4 that week. Two survived excavation. This is the only one discovered intact.

This specimen was made incredibly soft by the surrounding matrix. The thin veneer of glossy coloration has worn away, but can be seen on this specimen, which came from the same 2 ft x 1ft x 1ft block of matrix that fell out of the cliff into the bay. Half a dozen of these were collected from that and one other small, adjacent block that day, along with more than two dozen other species. Layer originally designated Shattuck Zone 18. Donated to the Delaware Museum of Natural History.

This specimen shows the original sheen and probably original coloration of the shell. It popped out of the matrix as you see it and required almost not cleaning. This specimen was stabilized, but stabilization did not change the appearance at all. Excavated from a chunk of matrix fallen from the cliffs into the Chesapeake Bay. Donated to the Delaware Museum of Natural History.

Sometimes you just get lucky. This geoduck (pronounced gooey-duck) was sitting with its mate in living state, filled with matrix, under a pile of landslide rubble at the water's edge. The exteriors of both shells were almost completely clean of matrix. Most other specimens were badly cracked in the matrix and would never have survived the fall. This shell was donated to the Delaware Museum of Natural History.

This was carved carefully from a block of matrix that fell out of the cliffs into the bay. Of the dozens that I found, this was one of the few that did not completely fall apart what it was separated from the surrounding sand. Though thicker than many shells in the same chunk of sand, they are extremely soft in this location and incredibly fragile. Donated to the Delaware Museum of Natural History.

Hello, I made a trip to Calvert Cliffs (Miocene) recently and found this interesting jaw segment with four teeth. It looks like some sort of fish to me, but I was wondering if anyone with more knowledge on this topic could tell me exactly what fish it is. Thanks, Evan EDIT: here are the measurements... Jaw... Length: 49mm, Height (including teeth): 27mm, Width: 10mm... Now for a single tooth... height: 11mm-13mm (depending on the tooth), Length: 6mm, Width: 4mm P.S. I tried to post additional pictures but the forum said I could only post 3.95 mb. the photo I origionally posted was 3 mb. I will try to attatch more photos in the comments.

Can you believe I found this just sitting there, sticking out of a block of landslide material on the beach and wiggled it out with a screw driver? Never found even a suggestion of one before and this is only one of two I found in three days of carving through that block to discover the rest of its treasures. The other, sadly, is not in as good a shape, but still a treasure! Found at Matoaka Beach, St Leonard, Maryland. -

I excavated this from matrix that fell out of the Drum Cliff Member of the Choptank Formation in Calvert Cliffs. I have looked at all the books and online resources I have to find a species, but nothing quite matches. If anyone has a species, I'd love to hear! This is the only specimen I've ever seen, let alone found. This one, like most other shells in the matrix, is extremely fragile and would not have survived exposure to the elements long. -

A recent landslide revealed an ancient bed of these paper-thin shells, all in pairs. They lived buried well into the sand and extended long necks up to the water to feed. Consequently, the shells did not get moved, just filled in and stayed in pairs after the animals died. They can be extracted mostly whole with some great care. -

Look what washed up on the beach! Scratches on it may be tooth marks. Found on Matoaka Beach, Calvert County, Maryland -

Collected on the beach after a storm. This is an index fossil for the Drum Cliff member of the Choptank Formation, Shattuck Zone 18. Choptank is the dominant formation at Matoaka Beach. Donated to the Delaware Museum of Natural History.

Unusual coloration. Typically these are red, sometimes with buff patches, but not usually all buff. The broken areas show the buff color to be a layer on the outside as there is red showing through the breakage. Collected from fallen cliff matrix in the bay containing index fossils of the Drum Cliff Member, Shattuck Zone 18. Donated to the Delaware Museum of Natural History

ID please - teardrop shapes fossil - Calvert Cliffs formation (Miocene)
Little_Bird posted a topic in Fossil ID
Hey friends, pulled this one from the surf at Flag Ponds Nature Park in Maryland. Flag Ponds is part of the Miocene era Calvert Cliffs formation on the Chesapeake Bay. Nickel for scale. It’s solid and heavy, teardrop in shape. Best guess from an internet search is a fossilized lingula brachiopod, but I can’t find many loose fossils, just ones still set in matrices. Any and all help is appreciated!

Found this at Calvert Cliffs. My first thought was a porpoise tooth, but is it possibly a seal? Thanks!

I'm Cody from Maryland me and my wife Cayla have been Shark tooth hunting at Flag Ponds Nature Park in Maryland for almost a year. We started out really slow. Had no idea what we were looking for but after the first few trips it gets easier and easier. Even though our favorite collection site is 2 hours from our house we try to make it there every weekend.

I'm new to this group so this is my first post and I hope I did this right. I found this fossil at Calvert Cliffs in Maryland and have no idea what it is. Any help would be greatly appreciated.
