Lee Creek North Carolina microfossil "hunt"

Recommended Posts

Adam86cucv

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.

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.

I love Lee Creek micro-matrix! Congrats on your finds, but be careful, this stuff is addictive!

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!

Nice finds!

This may help with IDs...

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.

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. :shrug:

Nice specimens.  Could you post a close-up, individual picture of the specimen circled in red below?

@MarcoSr

 

Thanks, I am find these little guys to be pretty neat. Here are a couple of pictures of the circled one... it's quite thin, if that helps too

Looks to be a broken gill raker.

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.

Definitely looks like a Cetorhinus gill raker.  That is a very rare species from Lee Creek.

Awesome, my son will be excited to hear about that.  I haven't shared any with him yet. :blush:

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. :P

 

Cheers.

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.
