Shellseeker Posted August 21, 2015 Share Posted August 21, 2015 (edited) I am cleaning/sorting last seasons finds. I went to my local fossil club last night and a friend was showing off a couple of boxes!!! of Megs, GWs, Makos, Hemis, Whale teeth, etc that he found last week. I am a sucker for color and took these photos of a Meg. There were likely 15-20 teeth that had this color combo, which I thought unusual for the Atlantic Ocean. Note the benedini in the background. As I consider this, maybe he said "Four or Five" and I was concentrating on the Teeth and "heard" Fortyfive. I have gone out 15 miles and that is quite a distance in a boat.

FLINTandBONE Posted August 21, 2015 Share Posted August 21, 2015 (edited) The colors look like some of the Megs found in the Bone Valley formation. That is where I would rather look for them. Diving out 45 miles and 85 feet deep requires a lot of work, money, and equipment. Edit: I do agree with you on the beauty of the color combo.

jcbshark Posted August 22, 2015 Share Posted August 22, 2015 Those are some great teeth Jack but I have to say in Venice the diving is much easier : ) I can spend 6 hours down and it's a 15 minute ride back to the ramp Every once in a great while it's not just a big rock down there!

Plax Posted August 24, 2015 Share Posted August 24, 2015 teeth this color are found off the NC coast. The megs are at or near the surface of the ocean floor and are black or gray with abundant epibionts. After the scooters flush the surface the deeper cleaner teeth including chubutensis (sp?) are exposed and have this coloration. This per an article in the North Carolina Fossil club newsletter by Jim Martin. Link to comment Share on other sites More sharing options...

I have frequently thought of fossilization on land, where iron creates red or sulpher create yellow-green, etc. Do fossils form the same way under oceans?

Plax Posted August 26, 2015 Share Posted August 26, 2015 (edited) these fossils have only been exposed at the surface of the sea floor for 10 or 12 thousand years during our current interglacial period. The glacial periods are much longer and these fossils were nearly or actually exposed on land. They were of course originally deposited in the sea. The Pungo River Formation teeth at Aurora had this same honey coloration despite being buried under many feet of younger sediment. Perhaps it was exposed near the surface before the Yorktown and subsequent formations were deposited? Shark tooth coloration is a complex thing. I've seen completely black cretaceous teeth turn white on the exposed side in the Woodbury Formation for instance. There are brown cretaceous teeth reworked in the base of the Eocene here in NC. These are in limestone. So chemistry is also a factor not just exposure. Edited August 26, 2015 by Plax Link to comment Share on other sites More sharing options...
megaholic Posted August 26, 2015 Share Posted August 26, 2015 Jack, Here is a few of the chubs I just got diving out there a couple weeks ago. Same colors. As plax said, any of the teeth I found visable on the surface were black, and all the ones that I fanned down to find were the brown color. All the species showed the same colors. (Hemis, megs, chubs, tigers). MH "A man who asks is a fool for five minutes. A man who never asks is a fool for life". Link to comment Share on other sites More sharing options...
Shellseeker Posted August 28, 2015 Author Share Posted August 28, 2015 Gorgeous Teeth !!! I had this discussion with my regular hunting partner who worked in the Bone Valley Phosphate mines for decades. He would describe uncovering areas that had thousands of yellow-green shark teeth and moving not more than 300 yards to where all the teeth were red-brown hues. I have adjusted my thinking to where I now think that a shark tooth can fossilize to any of the different hues without ever being on dry ground... (i.e buried under the bottom of the sea floor) The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
