Silurian mystery fragment

[aek]

Any idea what this could be? Very tiny..about 2mm. Silurian , crab orchard.

Better photos that are more in focus would really help.  Reminds me of mineral whisker growths but I can’t remember what they are called or how to confirm this.

Here's more photos. Really difficult to photograph. I need a better microscope.

Amazing- thanks for your help!

It should be noted that the genus Chonetes was rather a general ' waste basket' taxon but has now been split into many different genera. Chonetes is now limited to a couple of species from Europe ranging from Early to Middle Devonian. I think that C. vetustus was renamed C. vetusta. I can find no record of whether Foerste's species is still accepted or to where it has been reassigned if it has.  I do know that the other species to which Foerste compares it, Chonetes cornutus, is now Strophochonetes cornutus. Strophochonetes is Silurian (Upper Llandovery to Wenlock) but seems to be limited to Europe, Algeria and Anticosti in North America. It had long, hollow spines.

Interesting and thanks for the info.

There's not much, if any, taper to it. Perhaps it's a root?
