  1. I have been working on a chunk of dried matrix from Matoaka. As I dusted it off with a brush, I noticed this mesh-like material. The photo is magnified 4x, & the mesh is estimated at 4 cm across. It looks very thin & fragile, so I am not sure if I should try to remove it or just leave it be for now. This is the largest chunk that I have at home, so you know it will kill me to leave it like that. I also found a tiny little ecphora & a tiny crab claw in the same matrix, so I know it is good material. Any thoughts on this? Thanks!
  2. Canine Conundrum

    Hi everyone. I found this tooth at Matoaka on Saturday, August 25th. It tinks when I tap it on china, or up against shark teeth. It is hollow. Fellow fossil hunter, JPC, suggested it is a mammalian canine tooth. Question is, which one? Any suggestions? The ruler is in cm. It looks basically the same on both sides.
  3. Choptank Formation Mystery

    Hi everyone, I found this odd fossil while hiking along the Bay Saturday. I almost left it because I thought it was just a shell, but it has fossil-like characteristics. It is 3.5 cm at the base & 2.5 cm tall. It is 1cm at it's widest point. Thoughts??
  4. Spinifulgur spiniger

    From the album Calvert Cliffs

    Whelk, Siphonal devexa Aperture view Middle Miocene St. Leonard, Maryland Choptank Formation Drum Cliff Member This is one of four I found in the fallen matrix in four days of excavation. It is the only one that I found intact.

  7. Perna conradensa

    From the album Calvert Cliffs

    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

  8. Chesapectin nefrens

    From the album Calvert Cliffs

    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!

  9. Mussel With Both Valves

    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.
  10. Volute Snail

    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.
  11. Sea Snail

    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.
  12. Whelk

    Internal mold contains two complete micro Macrocallista sp. valves, along with a few broken pieces of other shells. The small circular hole on the aperture side is a predation hole, probably from an Ecphora snail. Collected from matrix that fell out of the cliffs into the Chesapeake Bay. Donated to the Delaware Museum of Natural History.
  13. Geoduck Clam

    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.
  14. Hello, I am seeking help identifying the fossil(s) in this rock. I am new to fossil collecting myself and found this on a chesapeake bay beach well known for miocene fossils in maryland. I spoke to someone that is familiar with the area and they said that it looks like it could be a Devonian fossil that got trapped in asphalt and that it is possible that it has been displaced from its original location. I am not sure if it is an imprint or a fossilized animal and I do not know how or if I should try to remove some of the surrounding rock for identification. The pattern on the side as well as the central point are of interest to me. Thank you! It is 2 1/2 by 3 1/2 centimeters
  15. Hello everyone, I apologize for the delay in making my report, but my latest trip was delayed by an upper respiratory infection. I took this past week off from work, with plans to visit both Matoaka and Flag Ponds, but then the virus hit and so goes the best laid plans of mice and fossil hunters. By Thursday, after four days of long naps and lots of fluids, I decided I was well enough to make the hour and a half drive down. I also thought that some sunshine would do me good. The day was gorgeous, not the normal, swampy heat that my home state of Maryland is known for. We call it, 'the air that you wear.' Surprisingly, the crowd was small. for such a beautiful, sunny day. I arrived at the cliffs around noon. High tide was around 9:30 that day, so while I would have preferred to go earlier, I waited for the tide to roll out a bit. The waves were a bit stronger than I expected, so I am glad that I waited. It was not a day for teeth because I found nothing other than a few tiny lemon shark teeth. But after meeting Igotarock and seeing her report, I had shells on my brain more than teeth this time. Whodaman, I was not feeling up to going all the way up the beach to the second cliff, but I have been eyeing it up for weeks. It is on my list for a cooler day or maybe a day when I can get an earlier start. The material that fell down a few weeks ago at the first run of cliffs is still revealing gems. On my way to the fall, I made the mistake of slipping on the clay ridge at the base of the cliffs. I know that area is very slippery and I try to avoid it, but I stepped up on it for a minute because the sun had dried it fairly well so I thought I was safe and I wanted to look at a very large clam shell. On my way back to the sand, my feet both went out from under me at the same time. Fortunately my bum hit the sand and not the harder clay. I banged my left wrist up a bit and it was very sore last night, but no permanent damage. After sitting for a bit and making sure there was no real damage that would keep me from going on, I made my way to the fall, found some promising chunks and put them in a bucket that I had brought along with some bubble wrap. Tonight, I got out the toothbrush and the dental pick and revealed this,
  16. Busycotypus sp.

    From the album Calvert Cliffs

    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.
  17. Busycon spiniger

    From the album Calvert Cliffs

    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.
  18. Dugong Bone

    From the album Calvert Cliffs

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

    Collected from landslide material in the bay. Donated to the Delaware Museum of Natural History.
  20. Clam

    Collected on the beach. Donated to the Delaware Museum of Natural History.
  21. Cup-and_saucer Snail

    Collected in landslide material in the Chesapeake Bay. Donated to the Delaware Museum of Natural History.
  22. Cup-and-Saucer Snail

    Due to the extremely fragile nature of this specimen, and the species in general, I was loathe to clear out any more of the matrix from the interior of the shell, so bits and pieces of other shells are present. The large central piece is the inner "cup," which attaches to the "saucer" at only a very small point in the tip. Collected from landslide material in the bay. Donated to the Delaware Museum of Natural History.
  23. Gastropod

    Collected from matrix from Shattuck Zone 17 that washed into the Chesapeake Bay by landslide. Donated to the Delaware Museum of Natural History.
  24. Whelk

    Collected from matrix a block fallen in the bay containing index fossils for the Drum Cliff Member, Shattuck Zone 17. Donated to the Delaware Museum of Natural History.
  25. Ecphora Snail

    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
