Thanks quagga.... My young lad came across picture of equisetum fluviatile - water horse tail colony. Does look identical can even see on the picture the same characteristics as on the fossil. Always wondered what it could be. Cheers....
You're right quagga; I was not firing on all cylinders.
To include Equisetites, we should perhaps generalize to the class level - Equisetopsida (Sphenopsida), but we could probably come down to the Equisetales.
Chris: if you could tell us the location of the quarry (the more precise the better) (and how deep in the quarry), that might help us narrow down the age of the rock, and thereby allow us to be a little more specific on the identity of your fossil.
Good, thanks Chris.
Scout Moor Quarry spans the Lower Coal Measures (mudstone, siltstone, sandstone), Rough Rock (sandstone, known for some large tree fossils) and Upper Haslingden Flags (sandstone), 314-316million years ago - Upper Carboniferous.
So the Calamitaceae were still around (not extinct until Lower Permian). And so were the Equisitaceae.
Does this give you any clues, quagga?
