Cornulite worm tubes found in the Kope Formation. These small creatures existed in the Ordovician Period. Typically, I find them attached to brachiopod shells specifically in the ridges. So it was change to find them by themselves in the gravel I was screening for scolecodonts. Fossils found in Carroll County, Kentucky.

With the striations on the side they almost look like a horn coral. I've never seen one up this close.

I agree they do look like small horn corals but I am pretty sure they are cornulites. There are no septa at the open end of the horn shape.

The striations are hardly detectable without a microscope.

YEP ! Very good shots, Michael ! No confusion is possible with Tentaculites either.

Interesting! Usually, in this area they are epibionts... somewhat uncommon to find them solitary.

I have been working an outcrop in which they are prolific, and came across this rather unusual association with a trilobite:


I have also found colonies of the critters encrusting firmgrounds.

Too, I have found other unusual associations at this outcrop:


Cheers, Solius.

I guess it is possible these creatures were attached to a brachiopod or rock. The fossil broke free over time and got washed into the sediment.

A new one will be shown soon that has a bryozoan attached to it.
