Kind of reminds of a primitive fish.... just a guess ... with fins dorsal and anal fins...

That is interesting... and I agree, it does *look* like fish to me as well, but I've not seen anything like it before. Might be worth sending a photo to Martha Richter at the NHM?

Amazing specimen..! Most of the scorpions I've seen are a lot less impressive than this, but you need a specialist here. I suspect there's a decent chance it's new, simply because such good ones are so rare. The man you want here is Jason Dunlop, at Berlin - will send you a pm.

Two major references on fossil scorpions are:
Kjellesvig-Waering, E.N., 1986. A restudy of the fossil Scorpionida of the world. Palaeontographica Americana 55, 1–287.
Petrunkevitch, A.I., 1953. Palaeozoic and Mesozoic Arachnida of Europe. Memoirs of the Geological Society of America 53, 1–122.
There's a monograph specifically on British Carboniferous ones:
Pocock, R.I., 1911. A monograph of the terrestrial Carboniferous arachnids of Great Britain. Monographs of the Palaeontographical Society 64, 1–84.
A century old, but would still be a good starting point. Should be in most UK university libraries, which the other two might not be.
The easy way to get an ID, however, is to contact Jason!

Joe.... Many thanks, Ive replied to your message....
Lucy.... Thanks for the references, we have been a bit stumped with a few finds and not knowing where to look is quite frustrating...Most of what we find were 'ok'ish' on ... Different species of bellinuras is quite daunting...

Peter...Yes its a cracker... It belongs to a friend of mine and as you can imagine, he is over the moon with it... Has anyone got any experience with Cyclus... Im looking for a more specific ID than just 'cyclus'... Upper carb, Duckmantian in age.... Heres a part & counterpart... I dont know if the preservation is detailed enough to take the Id further, but they are the best I have ever seen from the UK... Attachments:

Tim.... I think I saw that specimen.... is it on Han's website amongst the 'Little animals of the coal swamps'?...Jason sent me a CD with most of his papers on a while back ...maybe its on there, although he is very 'active' publisher... Blink and youve missed a dozen... I may of just missed it....
Peter... Thanks....Yes LOTS of enjoyment finding them, then finding out what they are.... slowly putting a collection together...
Any help with the cyclus species greatly appreciated...

Hi, a recent duckmantian find, the closest to an id i've got is Pygocephalas (anthropalaemon) dubious, although this one is larger and a slightly different form on the headshield, any help much appreciated. Cheers. Attachments:
