Hey all! Throughout my many years collecting from around the Cotswolds, there has always been one constant: these weird, tubular structures. Originally, I thought them to be corals, when I was much younger. More recently, I have IDd them as the ichnofossils of a Serpulidae. If anyone could confirm or disregard this ID, I would be very thankful!

Finally, here is a picture of them in Cotswold stone, without being removed:

I'm pretty sure that serpulid is right.

They're not actually ichnofossils as they were deposited by the worms to live in. Worm burrows, with no deposited tube, are ichnofossils.

Right, thank you! It's reassuring to know I was right!
