DoubleD843 Posted January 24 Share Posted January 24 Initial thoughts after doing quite a bit of research- Eagle Ray tooth plate. Not 100% sure on this. As far as the specific rock/mineral containing the fossil….perhaps rose quartz? Totally a shot in the dark here. Would appreciate any feedback!

Tidgy's Dad Posted January 24 Share Posted January 24 Where was this found? Looks like a crinoid stem to me. Not rose quartz but a silicious limestone, I should think. 4 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
DoubleD843 Posted January 24 Author Share Posted January 24 Crinoid stem! & Silicious limestone, right on! You two are very skilled- I really admire the intelligence! Believe it or not I found it yesterday lying under a random pile of chert in STL, Missouri. I’m curious by nature and have always been drawn to fossils and minerals. thank you both :) 3 Link to comment Share on other sites More sharing options...

It may actually be chert it's preserved in. Fossils are preserved in chert sometimes. 1 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Coco Posted January 25 Share Posted January 25 Agree with the above. However, I have seen several of your requests for identification without any measure. In the future do not forget to give the size, in cm or inches only, it helps a good identification. If you have nothing to measure, you can print the paper centimeter that I put available in my signature and make your photos with, let appear a box with the size or specify that the boxes are 1 cm side.

patelinho7 Posted January 25 Share Posted January 25 For reference, ray plates consist of bone material. It is highly unlikely if even possible at all that a ray plate would be completely replaced with minerals like that. 1 Link to comment Share on other sites More sharing options...

Coco Coco- thank you for the helpful suggestion and advising to take pics w/ measurements, I agree that this will help further identify this thing. I will absolutely do this once i get back. I appreciate it! 1 Link to comment Share on other sites More sharing options...
