Al Dente Posted November 12, 2014 Share Posted November 12, 2014 I recently went to an Eocene Castle Hayne Formation quarry in Eastern NC. I found a few nice fossils but not a lot of stuff. The collecting area was fairly small. Here's a picture of the top of the Castle Hayne at this location. There are a lot of solution cavities in the upper layer. Green clays that oxidize to a reddish brown will fill these holes. You can see some of the clay filling a large hole down to the left of my bucket. Sometimes teeth can be found in these clays. Here is an auriculatus tooth found in the clay. The other picture has a piece of Cylindracanthus (rostrum from a fish). 1 Link to comment Share on other sites More sharing options...
Al Dente Posted November 12, 2014 Author Share Posted November 12, 2014 Echinoids are the more common finds at this quarry. Here is Echinolampas appendiculata, one of the more common echinoids in the Castle Hayne. Also common is the sand dollar Periarchus lyelli. This one is larger than what is normally found. Here's the bottom of one of our larger echinoids, Linthia harmatuki. These are fairly rare, I've never found a whole one but I have seen other collectors find them. 1 Link to comment Share on other sites More sharing options...
Al Dente Posted November 12, 2014 Author Share Posted November 12, 2014 I think my find of the day was this nautiloid Eutrephoceras carolinense. Most of the living chamber is present. Here is a photo of ground water seeping into the pit. Iron bacteria is feeding on the iron dissolved in the water forming bacterial mats. People who use well water that comes from this formation often have problems with iron staining their clothes. 1 Link to comment Share on other sites More sharing options...
Shamalama Posted November 12, 2014 Share Posted November 12, 2014 That looks like a fund place to hunt, even if the area is small. The nautiloid is very cool! -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave.

fossilized6s Posted November 12, 2014 Share Posted November 12, 2014 I love that Nautiloid also! Id be happy with any of those finds.

Plax Posted November 12, 2014 Share Posted November 12, 2014 wow! that Linthia isn't usually found with Periarchus lyelli. Any protoscutella sp? Am guessing that more than one of Kier's biozones is present? Link to comment Share on other sites More sharing options...
sixgill pete Posted November 12, 2014 Share Posted November 12, 2014 Great finds Eric. If that is where I think it is, that is the most complete nautiloid I have seen from there.

JohnJ Posted November 12, 2014 Share Posted November 12, 2014 Very interesting finds, Eric. Looking forward to more images of your echinoids. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Al Dente Posted November 13, 2014 Author Share Posted November 13, 2014 wow! that Linthia isn't usually found with Periarchus lyelli. Any protoscutella sp? Am guessing that more than one of Kier's biozones is present? At the older pit down the street I found Protoscutella. I looked up Kier's publication to see what he lists with harmatuki. His "Middle Zone" where harmatuki occurs also has three sand dollars- Periarchus, P. plana and P. conradi. This seems like a strange combination for a single zone.

MarcoSr Posted November 13, 2014 Share Posted November 13, 2014 Eric Great pictures. I really like the nautiloid. These days it is great to get into a quarry even if it has only a small collecting area. Marco Sr. "Any day that you can fossil hunt is a great day."

Jeffrey P Posted November 13, 2014 Share Posted November 13, 2014 Wow! Great finds, Eric. Especially the nautiloid. Very cool. Would love to see that huge echinoid cleaned up and prepped. Thanks for posting. Link to comment Share on other sites More sharing options...
RickNC Posted November 13, 2014 Share Posted November 13, 2014 (edited) Those are spectacular specimens. Thanks for sharing them. I have an echinoid which I identified as Linthia sp. Unfortunately it is not complete. Edited November 13, 2014 by RickNC Link to comment Share on other sites More sharing options...

Al Dente Posted November 13, 2014 Author Share Posted November 13, 2014 Eric, Awesome report and great photos! How big was that ric? I forgot to measure it but somewhere around 2 inches. I was cleaning the serrations with a safety pin and noticed that the pin was making dents and grooves in the enamel even though I was using a light touch. The enamel was very soft. I've never seen that happen before. It must be leached of some of it's mineral content. Link to comment Share on other sites More sharing options...
