The Dudley council website states that Tentaculites ornatus is common at Wrens Nest:

Hi all. Being unfamiliar with either I’ve Googled some images. I’m  wondering if specimens of either of the id’s given, branch, as the one shown appears to.

or is it just crushed
Cheers, Bill

Hi Bill, I was assuming it was crushed, but yes it does look as if it might be a branch, maybe Dave can figure out which. Gets stranger by the minute.....do molluscs bifurcate? The only other thing that might be relevant is the supposed taxonomy of Tentaculites: Phylum: Mollusca, Class: Cricoconarida, Order: Tentaculitida. Dudley had a good museum with an impressive display of Wrens Nest fossils. Might be worth contacting them assuming it still exists...

Having viewed under more magnification i am almost certain that it is crushed, not branched.
I too thought it might be tentaculites ornatus. On initial cleaning i dislodged about 5mm of the pointed end!!
