Lee Creek Matrix Under A Microscope

[hokietech96]

@Al Dente Thanks for the feedback.  Very well could be.  I actually think that is a better fit than my original guess.  The groove is probably worn for the root as well.  The only thing that makes me question C. Macloti is the right side of the root looks complete and looks more of a cusplet than a serration.  

 

Tis is one of the C Macloti I have found

I found this unusual looking tooth this week.  I assume it is some type of symphyseal tooth.  The second tooth I can not decide if it bendini or thresher.  Each tooth is 2MM. Any feedback would be much appreciated.  @Al Dente @MarcoSr @sixgill pete Thank you so much for taking a look.

Here’s a discussion on teeth that look like your second tooth- http://www.thefossilforum.com/index.php?/topic/41260-lee-creek-fish-and-shark-tooth-id/

Thanks for the link!  Tons of information there to digest.  C. Parvus picture on Elasmo looks very similar to the tooth and I do not see any nutrient groove on my tooth.  Thanks for all your help.

Nice finds! Especially that little tooth!

Eric provided a link to a good applicable tooth discussion for your second tooth.  Between Alopias and Cetorhinus I lean toward a Cetorhinus ID.  The second picture of your first specimen definitely doesn't look like anything that I'm familiar with.   That second picture makes me think the specimen is a fragment of a larger specimen.

Just wanted to continue with this thread since I spent some more time looking through Lee Creek Matrix.  Here are some cool teeth and a couple other items that I found recently.  I believe I found my very first Rhincodon (Whale shark tooth)  @Al Dente @MarcoSr @sixgill pete.  Enjoy the pics.  

 

1. Rhincodon - 4-5mm

 

2. Scyliorhinus - Catshark

3. some type of catshark

4.  2mm Brachiopod

5. 2mm piece of bone.  The one side is really cool looking.

Yes.

It's a clam. The two valves are mirror images of each other. Brachiopods have a different symmetry. The only brachiopod I've ever found at Lee Creek was Discinisca which is pretty common. It has a more round shape than your clam.

Thanks for taking a look.  Very excitied for the Rhincodon.  I dont know to much about Brachiopods so this is really informative for me.  Thanks again.

I wonder if this isn't some sort of fish scale ?

The color and texture really looks like bone to me.  I dont have much experience with fish stuff so I never even thought a fish scale can look like that.  I whould have thought it would flat on both sides?

This photo reminds me a bit of the last plate of a chiton, which may look like a, but 2 mm is really small.

I see what you are saying, but the other photo of the piece makes it look too thick and chunky to be a chiton tail valve.  Plus I don't see any evidence of insertion plates although I suppose they could be broken or worn away.  Interesting thought, always good to consider and maybe it looks different in person than I am interpreting.

Do you want me to take better brighter pictures?

Probably not necessary.  It appears in the first photo of the object in question (#5) that the piece is thick, i.e. that side is not concave.  Is that correct?  A chiton valve would usually be shaped like an arch in cross section.

[hokietech96]

That is correct.  It not concave.  I think it is bone personally
