This is a large example of this Dipnoan lungfish from the Eday flagstones of Orkney, and very unusually there is a female Microbrachius dickie on the same plate.
Superb skull, tail, and scale detail. The tail and some of the main body were buried in matrix when found, and has been prepared professionally, revealing finer scales on this part of the body, as can be seen from the photographs.
Also on this plate is a very rare Microbrachius dickie, a tiny antiarch recently revealed to be the first sexually reproducing creatures known.
All in all, a cracking good double species fossil for the collection.
