cngodles Posted December 11, 2019 Share Posted December 11, 2019 To date, I've found 4 teeth, all in the same general area. One is shallow, the others are a big longer. The 3rd is a bit broken, I don't think I have a photo online right now of it. All are attached firmly to the limestone and I don't have any hope of ever getting them out clean. 1st Tooth: 2nd Tooth: 3rd Tooth No photos of this one. Sorry I promised 4 teeth, sadly only photos of three. 4th Tooth: 12 Fossils of Parks Township - Research | Catalog | How-to Make High-Contrast Photos Link to comment Share on other sites More sharing options...

What is the exchange rate between pinkies and petalodus these days? Cheers. -Ken Link to comment Share on other sites More sharing options...

grandpa Posted December 12, 2019 Share Posted December 12, 2019 @cngodles Thank you very much for sharing such nice specimens. 1 hour ago, digit said: Always nice to go to bed with more information packed into the old noodle than what you woke up with. I treasure those days. @diginit I totally, fully, absolutely agree! Let me add a bit of advise, if I may: Sleep with cotton in both your ears. That way, regardless of what side you sleep on, the "old noodle" won't leak out more info than you took in that day. That MUST be what happens; otherwise I'd be a flippin' GENIUS by now. What da' ya' think? 4 hours ago, Fossildude19 said: I enjoy seeing these early shark teeth! @Fossildude19 ME TOO! @FossilNerd Aren't they cool. I have found a few in the Texas Penn., but not near enough. They are rare indeed, esp is such good shape 1 Link to comment Share on other sites More sharing options...

cngodles Posted January 25, 2020 Author Share Posted January 25, 2020 Tonight I found my 5th tooth. It has the most dimensional root I’ve seen so far. I polished two sides of the rock that is holding them. The rock is interesting enough by itself with an embedded brachiopod shell, a sea pen on the back and more. I also have the negative, which has the other half and shows extra detail. I’ll post that after this. 4 Fossils of Parks Township - Research | Catalog | How-to Make High-Contrast Photos Link to comment Share on other sites More sharing options...
cngodles Posted January 25, 2020 Author Share Posted January 25, 2020 Showing negative side.

cngodles Posted April 12, 2020 Author Share Posted April 12, 2020 Tooth 6, 7, and 8 have been found. The last two actually came out of the rock. Number 6: Number 7, was exposed to water. Includes root: Number 8, widest I’ve found.

cngodles Posted July 12, 2020 Author Share Posted July 12, 2020 Petalodus 9 - 13 Since my last post, I have found 5 more specimens of Petalodus to add. While the first 4 were found more in less in my comfort zone, in Brush Creek Limestone locally, the last one I found in a secondary location, about 10 miles North East. This is the Pine Creek Limestone, which is younger than my local limestone. While I have not yet identified my local limestone 100%, the Pine Creek has been verified by state geologists directly. This limestone is different compared to my own. It's more fissile, and falls apart much more easily. My limestone is more like solid cement. So first, the last 4 Brush Creek specimens: CG-0048 is just a tooth blade. It's very bright in color and both sides are broken off. Out of all my teeth, this was the first one I couldn't properly measure. CG-0055 is a beautiful specimen. In prepping I removed the crown. I was able to measure and photograph both sides before gluing it back on the base rock. CG-0058 was another low crown specimen much like my first. Only the labial view was photographed as I was worried about breaking it if I tried to remove it from the matrix. CG-0070 was my second ever broken specimen, whereas I never was able to recover the cusp. I was breaking apart limestone when I spotted the tooth cross-section. However a lengthy search never turned up the other side. CG-0087 is a nice specimen from a new location for me. This location is along a highway and hard to work, so I typically stop when I'm going by and bring a few boulders home with me. Typically they are littered at the base of the hill and there is only one possible horizon they come from. The Brush Creek is buried under the ground in this location, however is it exposed about 100-500 feet away. This is the first tooth I've found that had a very dark black coloring. The one corner did break, so I had to glue it back on. Lingual and Labial views below with scale.
