Found this fossil? In Nottinghamshire with bivalves, ammonite and gryphea
Not sure where to begin with it, seems to show 4 clear panels arranged in a kite from above. I'm thinking along a coral/plant line?
I can't quite get to grips with it my mind; please could you post some further photos - end-on and in close-up; please also give an indication of scale.
Also, where exactly? Town/ street/ postcode/ description.
Give me a good enough locality descriptor and I may get a better handle on the strata it came from.
I seem to be having some issues uploading photos from my tablet
However, if its a help, it was found on the surface off long lane in a field just outside of plungar, Nottingham.
Its listed on UK fossils website. The scale is roughly as wide as a 2p piece, this is true of the top 2 'panels' the lower two are fractionally smaller.
The shape from above is an upside down kite.
I think you have found the bottom half of a Pinna sp bivalve.
We have found many on the Holderness coast, the best one i have attached an image I hope it's ok.
