Another find from the river Annick (Irvine,SW Scotland) Thought it may be Stigmaria but would love to hear some expert opinions, it is 3 " long and 1.5" across. Donna
Yes, I think Stigmaria is a good call.
However, the pattern is rather irregular.
But interestingly, your specimen has similarities to this description from the
explanation accompanying a geological map covering part of Ayrshire:
"Genus Stigmaria. — Brong., 1828.
Several peculiar examples of this common root have been met with ; amongst
others, one specimen showing radiating scars of attachment of the rootlets. In the
centre of the scar is a raised doss or papilla with a small hole in the centi-e. The scar
is completed by a series of small ridges radiating in a circle from the central boss."
You can see some of that, especially in your photos two and three.
Brilliant and thanks for the fascinating information, I shall do my research, As a self confessed tree hugger I just adore this find
Nice find. It's a stigmaria fossil from the Carboniferous period, around 310- 320 million years old.
