This is my first time going to this location. I found some things I’m not sure of and others I think are pretty nice. Would love to hear some feedback. Scale is metric 
 

1. Coral or worn Crinoid? 
3. Love these brachiopods 

5. So many brachiopods 

12. Crinoid 

18. Gastropod? 
19. Brachiopod 

20. Brachiopod 

22 brachiopod 

24 brachiopod 

27 gastropod 

32. Crinoid? 
36. Gastropod? 
37. Bryozoan or worn Crinoid? 
49. Bivalve 

56. Cute little gastropod.

Sarah,

Your pictures are good, but REALLY dark! 

Try taking your pictures in daylight, or with a lamp directly above the items.

You could lighten them using photo editing software.

Example:

I think 18 and 36 are Platyceras sp.  gastropod internal molds.

I think 1 and 32 are  likely the remains of crinoid stem lumens.

Not sure on the brachiopods.  @Tidgy's Dad  @Jeffrey P  @Shamalama

27 and 56 may be Pleurotomaria or Glyptotomaria sp. gastropods.

20 and 22 looks like Mucrospirifer mucronatus, to me.

[Tidgy's Dad]

I'm not sure of the Mahantango brachiopods, I haven't studied them yet, though I certainly agree with Mucrospirifer mucronatus.

If 49 isn't a bivalve then it might be Athyris concentrica.

And 3. and some of the others maybe Devonochonetes scitulus?

Thank you all! I usually don’t collect in the Mahantango formation so all help is appreciated! Hopefully I can learn to love this formation since it’s everywhere in my area.
