Jaybot Posted August 27 Share Posted August 27 It’s long overdue, but I’m finally starting this micro thread. Been meaning to do this for a while. I only recently started paying attention to micros, and they are annoyingly very interesting- and fun . So please don’t hesitate to correct my amateur identifications. Enjoy! To start things off, 2 different Streptognathodus sp. from the Stark Shale. Both ~ 1.8 mm long #C1STARK : <==(don’t mind that, it’s just my reference number ) #C2STARK : A closer look: 10 -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...

Bullsnake Posted August 27 Share Posted August 27 Great photos! What is the 'pointer' to the left of the conodont in your zoomed in photo, a tool, or an edit? 1 Steve Link to comment Share on other sites More sharing options...

It’s a needle inside of the microscope to be used as a pointer, I unfortunately can’t remove it. 1 -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...
Jaybot Posted August 28 Author Share Posted August 28 (edited) I think this one is a broken Prioniodina, but I’m still unsure. About 1.5 mm long.

bockryan Posted August 28 Share Posted August 28 (edited) How does one store these? Are they on large enough pieces such that it isn't that difficult? Edited August 28 by bockryan Link to comment Share on other sites More sharing options...

Yes, but I still just have these shale sections laying on my desk- haven’t decided how to store them.

Jaybot Posted August 28 Author Share Posted August 28 A quick break from conodonts; here is a mystery fossil. I have never found anything like it, any ideas? My first thought was an echinoid spine. From a Cherryvale fm. hash plate A close up: 1 -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...
Coco Posted August 28 Share Posted August 28 A sea urchin spine is generally composed of calcite and has a fissile plane approximately 45° from the axis of the spine. I have never seen a sea urchin’s spine made of plates as in the photo, which makes me doubt its identification.

I suppose my echinoid guess is not probable then -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...
Coco Posted August 28 Share Posted August 28 I doubt it, but on the other hand looking at your image again, it makes me think (perhaps wrongly) of an ophiure (= brittlestar) arm which has plaques on its arms. Check out these images of current brittlestars to get an idea: MY LINK Coco 1 2 ---------------------- OUTIL POUR MESURER VOS FOSSILES : ici Pareidolia : here Ma bibliothèque PDF 1 (Poissons et sélaciens récents & fossiles) : ici Ma bibliothèque PDF 2 (Animaux vivants - sans poissons ni sélaciens) : ici Mâchoires sélaciennes récentes : ici Hétérodontiques et sélaciens : ici Oeufs sélaciens récents : ici Otolithes de poissons récents ! ici Un Greg...

Jaybot Posted August 29 Author Share Posted August 29 I figured out how to remove that needle/pointer- it was sort of in the way. Here’s a partial cladodont tooth from the Cherryvale fm., on a hash plate. It’s ~2.5 mm from tip to root. 2 -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...
old bones Posted August 29 Share Posted August 29 @Coco is correct, that is a partial ophiurid arm segment. 1 Link to comment Share on other sites More sharing options...
Jaybot Posted August 29 Author Share Posted August 29 Thank you @Coco @old bones! That’s exciting for me, as that’s my first piece of brittle star I’ve found. They are extremely rare here from what I’ve heard; maybe there is a complete one out there . -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...

Jaybot Posted August 31 Author Share Posted August 31 Here’s a conodont that I am not too sure on the id. I’m thinking maybe a partial Ligonodina? ~0.8 mm. #C4STARK 3 -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...

Jaybot Posted September 4 Author Share Posted September 4 Found a broken Ptychodus whipplei tooth yesterday.. bummer in one way, but that means we can take a look at the internal structure . Glacial deposits, E KS The tooth measures 10 mm from ventral to dorsal, the microscope image is the tip of the crown. 1 -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...
Jaybot Posted Monday at 03:14 AM Author Share Posted Monday at 03:14 AM (edited) Here’s a view of the enamel on this well mineralized Odocoileus virginianus m3 molar: https://www.thefossilforum.com/gallery/image/62912-odocoileus-virginianus-m3-molar/?context=new I wonder if it is mineralized with vivianite.

Jaybot Posted Tuesday at 02:12 AM Author Share Posted Tuesday at 02:12 AM This is the tiniest cladodont tooth I have found- measures ~1.4 mm APL! Also, it is my first time trying photo stacking (I think it makes a big difference). 2 -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...
