I don't get a great sense of the specimen, but I suspect you are seeing:
- echinoid (your 'skull')
- belemnite, or maybe something else (your 'tooth')
- bivalve (the shell)
Hello Michael, very nice!
I don't know were you found it but to me it looks to be a multi block death assemblance containing the bivalve Pinna lanceolata?
Usually these assemblances are a bit of a mix up of all the different types of shells from that time zone.
Yes - Pinna - could be.
Forget the echinoid I suggested.
Still could do with handling it (oh well!)
Failing that, some prepping to disclose more of the individual fossils could help.
hi i had a look at pinna and it does look very much like it. im go pics with my findings. thanks alling to work at it a bit and see if i can figure the whole thing out. will post
well thank you i have been chipping away at the fossil and although i found it hard to picture any differently than my initial image i discovered that the part i thought was the roof of a mouth is ......a broken piece of the upright part which is now a 100mm long pinna lanceolata also i found a large shell hidding under the small bivalve impression which is great but i dont know what kind.
I found the fossil on the beach at Robin Hoods Bay, just a random loose rock. mike
Thought it looked familiar!
Find these assemblances on the Holderness coast, hard to split open but when you do they could contain anything, belemnite, ammonite bivalve but my favourite is the gastropods.
Hope it's ok michael as i have attached an image of a Pinna sp that i found on the Holderness.
