Definitely a ray and as you

Definitely a ray and as you suggest Dorset.Mushroom very likely the Thornback due to the density, size and shape of the thorns on the tail. There are a few species but I dont think any other species has thorns to compare with this. Cuckoo ray has thorns but they arent like this, they are much smaller and more like teeth on a jig-saw blade than these big rose thorn-like structures. Painted Ray has a smooth tail as far as I can see in pics.

I think its safe enough to say it is Raja clavata, possibly a female as they have the more impressive thorny tails.

Very interesting pics of the cartilaginous skeleton Paul.

thanks both for amazingly

thanks both for amazingly quick responses. The absence of a skull resulted in some very weird dreams on Sunday night. And it shows I don't know one end of a fish from the other !

Its a bizarre object to find Paul, no doubt about that. Kind of thing they use when designing aliens in movies.

Rayback remains

This looks like what we used to throw back after baiting our crab pots with 'raybacks' which were various ray species after the wings had been removed for human consumption. This bait was tough enough to keep the crabs in the pots for longer particularly in the winter months when it was not possible to empty the pots daily because of bad weather.
