Nano fossil? (Keasey Formation).

[OregonFossil]

Location: Eocene, Keasey Formation NW Oregon.

 

Length: 567 nm

 

I've been using the following resources:

 

1. Microfossils by Armstrong & Brasier, second edition

2. ANSP Diatom New Taxon File

3. JSTOR research data base

 

The item of interest is center image (5 mpx file), lighted bt 5600K sidelight, 10X objective.  I have a sample gastropod encased in Keasey mudstone (formation can be from 1000 to > 10,000 feet in depth), and thought I'd scape a tiny bit of the the mudstone on a slide to view under my compound scope (use for solid specimens with a LED video light to the side).  The item of interest is the clear, tubular item (clear) in the left upper center. It measured 567 nm in length and I guess for width (didn't measure) is around 40 -50 nm. There is the clear funnel shaped item directly above near the edge of the image which might be the top to this item. I've spent about 4 hours trying to id the item and believe it is a Nano-Fossil of some type. Placed this inquiry here because it's a "what is it" and not an ID Micro/Nano fossil for the microfossil forum.

 Any guesses before I go insane would be greatly appreciated.

Brightened - I see the funnel shaped item, but what else are we looking at?

There are a number of things that may be something...

I was looking for the clear tubular item that you have circled. The original items is the longest, clear items (which you have circled). But I'll take any and all ID's you can give. I thought I was lucky to just find the longer item:)

Sorry, I can't help with any ID's. I was just trying to get a clearer impression of what you were looking for ID for, for anyone who might be able to help with ID's.

The number of Genus, Families, and species is amazing. Perhaps the most amazing thing is that due to the very small size mostly in sub 500nm size, a huge number can be found in a very small sample. Just something to do on a rainy day:) (or snow in this case).
