MarcoSr Posted August 30, 2013 Share Posted August 30, 2013 (edited) I want to thank Herb for sending me some Devonian matrix residue from the Columbus Limestone from Columbus, Ohio. The matrix was already processed and ready to look through. There was a very high fossil density with very little matrix left and very little other debris. I found a very large number of fish fossils. There were hundreds of fish denticles/scales and a good number of fish teeth. I’m posting the nicer and more unusual micros which I found. These micros were very small specimens ranging in size from .4mm to 2mm. If you place your cursor on a JPEG image you will see the file name which will have the specimen size. I have only identified the specimens as fish teeth or fish denticles/scales. If you can identify the specimens further please do so. Each matrix that I search makes me more of an avid micro tooth collector. If anyone has or can collect good matrix with shark, ray, and fish micros please send me a PM. Below are some of the fish teeth which I found: Below are some of the fish denticles/scales which I found: Marco Sr. Edited August 31, 2013 by MarcoSr 1 1 "Any day that you can fossil hunt is a great day."

busyeagle Posted August 30, 2013 Share Posted August 30, 2013 I always enjoy seeing your latest micros, Marco. Pretty neat to get to search material that is so much older than what we're used to here on the east coast. Link to comment Share on other sites More sharing options...

MarleysGh0st Posted August 30, 2013 Share Posted August 30, 2013 Interesting specimens! What sort of processing was required on this limestone matrix? Link to comment Share on other sites More sharing options...
Ridgehiker Posted August 30, 2013 Share Posted August 30, 2013 Great stuff. These are from screening only or was acid used to break down the matrix? Link to comment Share on other sites More sharing options...
MarcoSr Posted August 31, 2013 Author Share Posted August 31, 2013 Interesting specimens! What sort of processing was required on this limestone matrix? Great stuff. These are from screening only or was acid used to break down the matrix? Usually I receive raw matrix and do the processing (break down) myself. However, Herb processed the matrix and sent the residue to me. So I don't know exactly what specific processing took place. Typically limestone is processed (broken down) using acetic acid. Hopefully Herb will reply to this post with his processing steps for the Columbus limestone matrix. Marco Sr. "Any day that you can fossil hunt is a great day."
