Adam86cucv Posted October 3, 2018 Share Posted October 3, 2018 So I had bought from a certain online auction site some Lee Creek mine microfossil matrix a while back... I finally got around to looking over a little bit of it this evening. Attached are what I have found so far without any magnification. Link to comment Share on other sites More sharing options...
Adam86cucv Posted October 3, 2018 Author Share Posted October 3, 2018 The last 2 I am guessing is some sort of fish tooth? I haven't had a chance to look into IDing any of the finds yet, but would be grateful for any ideas anyone wants to throw out. Link to comment Share on other sites More sharing options...
NCSTer Posted October 3, 2018 Share Posted October 3, 2018 I love Lee Creek micro-matrix! Congrats on your finds, but be careful, this stuff is addictive! 49 minutes ago, Adam86cucv said: The last 2 I am guessing is some sort of fish tooth? Your last two pics are ray teeth. Keep your eyes open -- you'll be finding more. The little "U" shaped root is a dead giveaway, but look for variations, i.e. upper and lower teeth, and some from different species. Try a little magnification and you will find some great stuff. (My avatar pic is a less than 1 mm unidentified fish tooth from that same matrix.) Welcome to the world of Lee Creek micro's and Good Luck! Link to comment Share on other sites More sharing options...

Adam86cucv Posted October 3, 2018 Author Share Posted October 3, 2018 Thanks @NCSTer I never would have thought about a ray tooth. Thanks @ynot while waiting for the micro matrix to arrive I had searched a bit and had stumbled upon some info but I didn't bookmark any for quick future reference. It's definitely been fun just with my naked eyes. I've found as much, if not more than a not so lucky day at the beach. Eventually I will break out the lighted magnifying glass and the USB microscope. I will also be trying to get better pictures with the USB microscope. I think this may have opened a whole can of worms the search for microfossils and the persuit of better pictures of the microfossils. Link to comment Share on other sites More sharing options...
Adam86cucv Posted October 3, 2018 Author Share Posted October 3, 2018 I have debated putting my sifting pan set to work. The set I have is 1/2", 1/4", 1/8", 1/12", and 1/20" mesh pans. The 1/2" and 1/4" wouldn't do much besides remove the bigger pebbles and shell fragments. Not sure it is worth the effort, besides making the matrix I look through more uniform in size.

MarcoSr Posted October 4, 2018 Share Posted October 4, 2018 Nice specimens. Could you post a close-up, individual picture of the specimen circled in red below?

Here are a couple of pictures of the circled one... it's quite thin, if that helps too Link to comment Share on other sites More sharing options...
caldigger Posted October 5, 2018 Share Posted October 5, 2018 Looks to be a broken gill raker. Link to comment Share on other sites More sharing options...

I had to look a Gill raker up, seems to be a reasonable conclusion. I think I might have found another one slightly different but also broken in the batch I haven't photographed yet, plus some absolutely tiny shark teeth that I'll need to get out the USB microscope to get a picture of them.

Not sure it is worth the effort, besides making the matrix I look through more uniform in size. Indeed! Give this a try. I starting doing that once I got into picking micro-matrix. By separating the matrix into different size classes you can focus on each size independently. Much easier to spot the tiny little fossils when you are not having to look past the larger bits. You'll find certain types of fossils will group together into different size classes. Tiny Dasyatid stingray teeth like the little one with the double roots pictured above will generally be in the finer size class. Small conical fish teeth tend to slip into the really fine size class as well. I now classify all of my micro-matrix before picking through it--greatly aids efficiency for just a few minutes effort with the stacked sifters. Welcome to the wonderful world of micro-matrix--it's highly addictive and too late for you now. Cheers. -Ken Link to comment Share on other sites More sharing options...

Adam86cucv Posted November 14, 2018 Author Share Posted November 14, 2018 I had an opportunity to look through a bit more matrix tonight. Pretty little shells and some tiny neat little shark teeth. I have a couple of unknown bits but can't get my phone to make a decent picture of them. Link to comment Share on other sites More sharing options...

Al Dente Posted November 14, 2018 Share Posted November 14, 2018 5 hours ago, UtahFossilHunter said: How old are the fossils here? There is a mixture of ages for this material. The phosphate they are mining is the mid Miocene Pungo River Formation but the upper layers of the mine will fall into the shovels and mix with the other material. Pliocene Yorktown Formation and Pleistocene James City and other Pleistocene will be mixed in. The shells are mostly Pleistocene because the aragonite in the Pungo River and Yorktown is leached away at this location. Link to comment Share on other sites More sharing options...
