Shellseeker Posted March 17, 2020 Share Posted March 17, 2020 I am sitting at home, sorting ziplock bags of fossils collected in the last year. You know the problem. Too many fossils in the house. All these fossils came out of a Bone Valley Creek, definitely Miocene. For those of you who are fortunate enough to collect Bone Valley teeth, what is happening with the white on these teeth? Especially the Hemipristis.. A white tip. or the "bourlette" on the Tiger? 6 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
fossilnut Posted March 17, 2020 Share Posted March 17, 2020 Love the hemi. That is really neat. Didn't you have some freezing weather down there? 1 Link to comment Share on other sites More sharing options...
caldigger Posted March 17, 2020 Share Posted March 17, 2020 Wow, they're reverting back to the color they were when the shark was using them. Maybe some sort of reaction as the phosphate slowly dries within the core? 2 Link to comment Share on other sites More sharing options...

aplomado Posted March 17, 2020 Share Posted March 17, 2020 I love those colors! That would make a lovely display in a bowl or a shadowbox on the wall. 2 Link to comment Share on other sites More sharing options...
Shellseeker Posted March 18, 2020 Author Share Posted March 18, 2020 Thanks for all the encouraging comments. I had not seen this specific combination of coloring on BV shark teeth. If you consider the hemi, I have frequently seen the color combo of blue _grey enamel combined with tan or white roots. So, to me that's "normal". Here is one of my best: I thought of it as a possible 2 step process. Maybe the tip was exposed to sunlight for thousands of years while the rest was under ground. Interesting to speculate !!!! 3 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

I found a few of these teeth along the road back in November. They looked odd to even a novice like me! Mike 1 Link to comment Share on other sites More sharing options...
Shellseeker Posted March 20, 2020 Author Share Posted March 20, 2020 No Mike, have not figured out anything... The base questions are what triggers the color variations in the enamel and why are Bone Valley roots white. I have some understanding of the 1st, no understanding of the 2nd question 2 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
