A rare Monday trip; Waccamaw Formation


sixgill pete

Recommended Posts

Well folks, I took a day off from the grinds of the job and made a rare Monday trip into the Waccamaw Formation of Southeastern North Carolina. I met up with a few old friends and made a couple of new ones. The new friends have been doing a traveling fossil trip and were kind enough to share a few of their finds with us new friends. Mine was this beautiful (at least to me) large Texas ammonite; anyone have an idea on the species?

Anyways, we met early and took of for the site. Some of our forum members I know are familiar with this particular pit, but it was my first time there. It is well known for it's very rich molluscan fauna, the occasional great white tooth and the odd surprise. 

 

Upon arriving, I dug right in; no pun intended. This was my total take home for the day. 20170228_132532.thumb.jpg.b11032ac86b0af05ad69832fbb45c740.jpg

 

I could have brought out lots and lots more, but many of the bivalves, I already had through gifts and others bringing me buckets of matrix. I also left countless cone and olive shells for the next person.

 

I did find this rather nice great white, no root but very very few of the great whites from this site has roots. But it has great serrations and measures in at 1 3/8"

I also found this very cool crab claw, quite a surprise. It measures at 1 3/8", the same as the great white so it must have been a large crab. I know it is hard to ID crabs from just a claw, but if you have any thoughts ..............

I am in the process now of trying to ID these finds, something I am still learning how to do with bivalves and gastropods. I am going to start with 

6 gastropods and 2 bivalves, some I am fairly confident of ID, others not so. Please feel free to correct any ID I may give. I will add others as I have the time to photograph and put up. So, lets get on with it.

 

First what I believe is Fusinus (Heilprinia) caloosaensis, 1 7/8 inch a my favorite of the day. A real beauty.

Euspiria sayana, 1 1/16" ......... 58b724b3a40dd_Euspiriasayana1a.thumb.jpg.0caa789ac536c5305bc45813dc3f68ec.jpg   58b724b05e80c_Euspiriasayana1b.thumb.jpg.ae470c688a9dea277cbdae2c05f1c119.jpg

 

Terebra dislocata, 1 11/16" ...... 58b7251d602a4_Terebradislocata.thumb.jpg.631ae3a96a4f7083eebc7cb12a70088b.jpg

 

then this cool little thing. a Argopecten vicenarius cemented inside of a Anomia simplex by matrix ...........

Trachycardium emmonsi; 1 3/8 long by 1 3/4 wide ....... 58b726acd817b_T.emmonsi1b.thumb.jpg.82fa2f0c5f87cbcaefe46c03750ba364.jpg  58b726b21272a_T.emmonsi1a.thumb.jpg.74c72866c9a78d724cf499d6b93ecd2d.jpg

this one I am not sure. It is very muck like the T. emmonsi but rounder. In my reference, " Fossil Mollusks " Volume 2 by the North Carolina Fossil Club it matches another bivalve. 

Trachycardium oedalium. Any thoughts on this? 20170228_200527.thumb.jpg.75ea6af39f2ca71e855e79332095335f.jpg  20170228_200508.thumb.jpg.e41e0721174b823bc35d5c92612da907.jpg

 

Now this one, I am thinking either Busycon or Busycotypus. It is 1" long. Help!!!!

 

Busycotypus1b.thumb.jpg.6dcaed6bc4de07f37822ab344dc454b5.jpg  Busycotypus1a.thumb.jpg.0a47556c058757e122a4252da9c70a96.jpg

 

These three are the opposite of the last. Busycon contrarium? They range from 1 1/4' to right at 2"

We went to a different spot on the Cape Fear after leaving there. But that's for another day .......................................................................................

Hi Don  you have some Beautiful shells there, it's one of my favorite invertebrate fossil sites, that I've been to.  I found cool stuff from there just  by bringing matrix home to sift. Originally I just had shells from there from when Dr. Lauck Ward  had collected them for me on one of( Mid-Atlantic Fossil and Nature Adventures)  trips.  but now I have lots more since my first trip and stuff Dr. Ward had collected for me. Hope to hear about your cape fear trip soon

Great looking finds, Don. :wub: 

Nice variety - glad you got out, and did so well!

Ever find any marine mammal material in the Waccamaw up there?

Nice finds Don, that GW looks like it could have come straight out of bone valley:)

Every once in a great while it's not just a big rock down there!

Hi Bobby. As far as this site, I have never heard of any. I have heard of rare reports of vertebrae being found from other Waccamaw site. Here is a link to one on here.

Columbus County?! I need to look harder for these pits! All I've found around there are some snails and shells, but I thought they were Peedee Formation stuff.

 

Wow great to know this stuff exists down there. Ever hear about the whale they found in Lake Waccamaw a little while back (09 I think)? They've been finding a lot of ground sloth stuff there too (there's a replica in the Cape Fear Museum in Wilmington).

 

Looks like I'll be busier next time!

Thanks Don,  you beat me to it. There are more Waccamaw finds in my gallery titled, Fossils from Brunswick County.

Hi Don

 

You are pretty much spot on with your identifications.  The Cardium in which you question as Trachycardium oedalium I think is T. emmonsi based upon its "spiny-ness."  Also immature T. emmonsi are circular and become elongated as they grow.  It makes identification on the spiny cockles difficult.  Also you have Busycotypus spiratus and Sinistrofulgur contrarium.

Thanks Mike. I am slowly but surely getting better at IDing mollusks.

Sinistrofulgur is the left-handed whelk.  All other Busyconidae as well as the vast majority of all gastropods are right handed.

I have some small cetacean vertebrae from Nixon's Crossroads SC. Most of what is in my locally assemblage from there looks like Waccamaw (should be upper there) and Goose Creek Limestone. You're welcome to the verts if you can use them. PM me your address.
