I’ve recently bought some fossil shark teeth online to expand my collection beyond the local Maryland fauna (Miocene from the Calvert Cliffs and Paleocene from the Potomac River/Aquia Formation), and it occurred to me that perhaps there are some forum members who would be interested in sharing some of your finds or extras in exchange for mine.

 

The things I have to offer are shown below—mostly fossil shark teeth and a few other things. These aren’t all perfect, but there’s a good variety, including some less common species. I’ve collected most of these myself and have also listed a few purchased teeth for trade. If there’s something that interests you, hopefully we can help each other build out our respective collections. 

 

I have particular interest in adding Ptychodus sp. and Cretodus sp. teeth from the Cretaceous to my collection, but I’m open to a broad range of offers. U.S. trades are likely easiest for shipping, but I’m happy to consider international offers too.

 

Thanks for looking!

 

Quick summary of shark teeth available for trade by species (also see photos below):

  • Miocene from Calvert Cliffs - Alopias latidens (2), Carcharhinus sp. (5+), Carcharodon hastalis (1), Galeocerdo aduncus (2), Hemipristis serra (4), Negaprion eurybathrodono (5), Notorynchus cepedianus (1), and Physogaleus contortus (4)
  • Paleocene from Potomac River/Aquia FormationAnomotodon novus (2), Cretalamna appendiculata (2), Palaeohypotodus rutoti (3), Paraorthacodus clarkii (1), Striatolamia striata (4+), and unidentified sand tigers (4+)
  • Miocene-Pliocene from PurchasesCarcharocles megalodon (1), Carcharodon hastalis (2)

 

I. Shark Teeth Available for Trade

 

A. Miocene shark teeth from the Calvert Cliffs (unless otherwise noted):

 

Alopias latidens (thresher shark) - both pending

Carcharhinus sp. (gray sharks) – I also have others available. The tooth on the far right is from a Miocene exposure in Virginia (Westmoreland State Park).

Carcharodon hastalis (white shark, predecessor to the great white)

5f2b68700f108__Miocene_Carcharodonhastalis.jpg.79e40acf48875b0adb2978b06b4c403f.jpg 

 

Galeocerdo aduncus (tiger shark) – The smaller tooth on the right is from a Miocene exposure in Virginia (Westmoreland State Park).

Hemipristis serra (snaggletooth shark) - tooth A is pending

Negaprion eurybathrodono (lemon shark)

Notorynchus cepedianus? (sevengill cow shark) – This is most likely N. cepedianus though it’s a partial so I don’t know if it can be definitively ID’ed.

5f2b688a428e4__Miocene_Notorynchuscepedianus.jpg.bc539f19219654eadf0169d39a5b4f7b.jpg 

 

Physogaleus contortus (tiger-like shark)

B. Paleocene shark teeth from the Potomac River/Aquia Formation:

** I’ve done my best to identify the various sand tiger shark teeth below, but I may have made some mistakes.

 

Anomotodon novus (goblin shark) - both are pending (though I also have others)

5f2b6895b71b7__Paleocene_Anomotodoncfnovus.jpg.a8b65c49b6ddb82881df0158037e2050.jpg 

 

Cretalamna appendiculata (mackerel shark) - tooth B is pending

5f2b689c02056__Paleocene_Cretalamnaappendiculata.jpg.d36d52b5b8f06b3c53e0e5041892117f.jpg 

 

Palaeohypotodus rutoti (sand tiger shark) – I am pretty sure these are all P. rutoti due to the presence of basio-labial folds (see this elasmo.com page), but I could be wrong.

5f2b68a1e600c__Paleocene_Palaeohypotodusrutoti.jpg.af97ecdd68f2f05f2c942019c4716a52.jpg 

 

Paraorthacodus clarkii (no common name shark) - tooth is pending

5f2b68a6aadcc__Paleocene_Paraorthacodusclarkii.jpg.7ccd6d9941d6fef4af8559251a6b6b45.jpg 

 

Striatolamia striata (sand tiger shark) – I have others available too. - teeth A and D are pending

5f2b68acc493d__Paleocene_Striatolamiastriata.jpg.bed222f936e685c03a276f26ffc246eb.jpg 

 

Other non-striated sand tiger shark teeth – I’m unsure of the species on these; some may be Hypotodus verticalis. I have others available too. - tooth C is pending

5f2b68b473baf__Paleocene_SandTiger_unknown.jpg.d247c1a26ba6872e837f1c9a2538e266.jpg 

 

C. Purchased shark teeth available for trade:

 

Carcharocles megalodon – This tooth was collected by a diver from the St. John’s River in Florida and measures a little over 2.75” slant height.

5f2b68bc4eaf8__Purchased_Carcharoclesmegalodon.jpg.2a3cc470eb43e39d19afc53e2f672972.jpg 

 

I believe these are both Carcharodon hastalis – They are from an estate sale and their original collection location is unknown. They measure 1.7” and 1.2” slant height, respectively.

II. Other Fossils Available for Trade

 

A. Miocene from the Calvert Cliffs:

 

Ecphora gardnerae? (gastropod) – If this is E. gardnerae, it’s also Maryland’s state fossil.

Drum fish teeth

Ray crushing plate fragments – The two v-shaped ones on the left are Aetomylaeus sp. and the other two may be as well. I have others available too. - plate B is pending

My first trade has been successfully completed with @butchndad. We agreed to swap some MD and NJ fossils, as I've been wanting to hunt Big Brook/Ramanessin and he's been wanting to hunt the Calvert Cliffs, but neither of us has been able to make it to the other's neck of the woods yet. Through no fault of his, the U.S. Postal Service decided to hold onto the NJ fossils for an extended period of time (someone jealous of the included bounty perhaps?), but the package arrived safely and soundly today with some great examples of NJ cretaceous fossils! Thank you @butchndad!

My trade with @BellamyBlake is also now complete (his package to me arrived a while ago but mine took longer to wind its way north through customs). The items I received are below—a collection of shark teeth, ammonites, and belemnites from FL, SC, Belgium, and the UK. Thanks, @BellamyBlake!

 

I’ve now traded most of the shark teeth in my original post, but I have one more trade in process that I’ll also post a picture from as soon as the package on it’s way to me arrives.

My final trade from this post is complete. In exchange for some Maryland fossils, @will stevenson sent me a plethora of shark teeth and invertebrate fossils from the UK, Belgium, Kazakhstan, and Morocco, including many many extras. Thanks so much, @will stevenson!
