Chert fossils, inclusions

[Geojonser]

Hello

 

After doing some reseaech on some big Chert nodules given to me...I went back through some Chert that I found along the northern North Sea coast of The Netherlands...

 

I really like Chert...I have always been curious about mineral inclusions and/or fossils in Chert...I am having trouble finding laymans info on the subject...the info I do find is a bit overwhelming...

 

Im hoping someone could help me out identifying some of the things that I am seeing in my pieces...I have pointed to points of interest to me...

 

I have posted the photos twice...one in natural light and the one darkened...all the same stone...4" x 3" (10x7.5cm)

 

 

I see lots of pattern in these pieces...Plant, animal, bubble, scratch, fracture?...too much info...Im unsure...

 

 

This next photos are interesting to me because the area that I point to (this?) is the outside of the nodule and the grouping of grains (?) Seem to me to possibly be some of what I am looking at on the broken and, by nature, polised sides in the previous photos...

 

 

The next photos are of a different piece of Chert that had been painted...I am a bit weary about using paint remover on it...concerned about discoloring it...I wiil experiment on a flake later...

 

Anyway...also 4" x 3"...

 

 

next are 2" x 3"...same side at two different angles...

 

 

I appreciate any help identifying the "spots" in these two stones...if someone knows a link to a  "identify-stuff-in-chert/flint" resource for a lay-person, that would also be greatly appreciated...

 

Thanks in advance for your time

I think I'm seeing mostly foraminifera in these photos, but I may be mistaken. One would need to inspect them under a microscope and/or make some macro photos.

I will get bsck to this with some clearer macro and microphotos soon...thanks
