Fossils?

You did just fine. The only problem is that its still hqrd to see any real tructure in the concretions. They ould be fossils or, more likely , they are pisolites or oolites, both are internal structures in the pre "hardened" sediment that involves energy differentiation among bodies of slightly different densities or composition. OOlites re generally seen in limestone (but can also appear in shales and fine grained sands).

They generally indicate bank deposits and moderate energy down slope movement and segregation of the different chemical aggregates.

Im more leaning to pisolites (you can look em up in Google and reearch em further maybe you can get a thin section cut at some college nd look t em under a scope, thatll be most helpful)
Guessing from hand specimens cn get us maybe 70% there

The yellowish "tree like" stains are called dendrites. They are usually a mix of iron nd manganese (its called "wad" in mining). Its not a fossil but an indicator of ground water movement along rock frqctures

Thank you, I think you are right, I can even see so called twist fringe hackles which I had seen on other rocks and I didn't know what they were until now.

I think you could be right about pisolites, I didn't know inorganic processes could form rounded shapes like these ones.

you must be writing from a UK country. We use a term called "en echelon" fractures to describe what you are calling "Twiat fringe hqckly structure"
HAckly is a "habit' and "twist fringe" is a term that knitters use to describe some kind of a knot on carves.

Glad to be exposed to other terms used by folks

I read these terms in books. Example:

This author uses the phrase twist-hackle fringes arranged in en echelon manner.

I guess he uses various terms for specific parts of the en echelon, like plume, many of them related to feathers.
I have always wondered why terms in Geology are not standardized in a particular language, like Biology uses Latin, Medicine, Greek. While nomenclature of lava flows is in Hawaiian, we have Italian Breccia, which went intact into English, but in Spanish we use Brecha, its equivalent. While en echelon, is a geological term, its Spanish equivalent, un escalón, is not. This is kind of confusing sometimes.

Almost every batch of geological maps are commissioned separately and SAME FORMATIONS have dissimilar names. There is an International Committee for Stratigraphic Nomenclature in which ssame age and environment of depositional Formations are being given same names. This is a tall order because many of these similar units have slightly different source modes and pressure .
I looked up "Twist hackle" in the American Geological Institute's
Glossary of Geology. There were presented
a number of similar terms, the one Im familiar with is "tilt plane" because it relates to fractures that point toward the area where the stress were propagated.
I dont use the term much (I think the last time was several years ago
for a local mine map).
Even the word "plume: has several uses in geochemitry, geophysics, engineering geology and petrology(Each one different but all having a similar frame of occurence)

Its just one of the things we get used to because most geologists are specialists of a few areas on the map. Usually our first papers will try to have a series of cross references either before an abstract or at the end.
