Hi

This is one half of a nodule which I found at Runswick Bay, Near Whitby, England.
The object is in the bottom right of the nodule pic.
The other pic is a blowup.

Could this be a fossil?
I thought that it might be a Brachiopod.

Pete

it's a fossil all right. Possibly brachiopod, otherwise a bivalve.

Hi Frederick

Thanks for your comments.

It looks like I will have to retain a Mystery Objects page on my website.

Hi Folks

Yet another object.

Please work your usual magic.

This is the other half of the nodule from Runswick Bay.

Could this be a Belemnite?

Hi Folks

I've been told that this could well be a pair of belemnites presented in longitudinal section due to heavy erosion of the nodule.

Pete,

indeed they are belemnites.
Here's similar sectionview from Solnhofen nicely pollished LINK

HI Charles

Thanks for that.

I'm thinking about splitting the nodule again but I am afraid of damaging the existing fossils.

Pete,

I wouldn't do that if i were you, you could end up with "nothing". The nodule looks very solid to me, so extracting fossils from it without damaging them could be very difficult i guess...

Hi Charles

You are absolutely right, the nodule is very hard.
I have decided not to touch it and look for more similar ones next time I'm in Runswick Bay.

Under a magnifying lense, the nodule appears to be full of small fossil fragments.

Thanks for the advice

Pete

Object 1 looks like a Mimachlamys Varia to me.

Bad guess I think...
Mimachlamys varia is a recent shell, only.

That's not true. It might be not that old, but most of them are around 115.000 years old. I don't now what you call recently, but the Mimachlamys Varia is NOT only nown as recently at all!

Indeed, but this rock looks a lot older. That is why I think a brachiopod is the best option here. But with only a small piece of the shell I can't be completely certain.

Dear forum members, this kind of guessing around is not very helpful! At first skorpion should give us more information on the location and the possible stratigraphic origin of these stones (a bit of research in the www should set you on a right path). Without this it is nearly impossible to determine his pieces.

The piece on the first two pics looks like some sort of shell (like Frederik already wrote). The object(s) on the last two pics look like a pair of aptychi (mandibular parts of ammonites which perhaps also had the function to "close" the shell (operculum).

Best regards, Oliver

1e lijkt mij dat er een bevredigend antwoord gegeven is : schuine doorsnede van een belemniet
2e lijkt mij totaal zinloos een absoluut niet onderbouwd antwoord te geven op een 8 jaar oud topic van een lid dat reeds 6 jaar niet meer actief op het forum is

Klopt, ik had nu zelf niet gezien dat het topic al zo oud is.
Dan heeft antwoorden idd weinig zin

Ook als het om een oeroude topic gaat: de laatste foto toont toch geen belemniet!
Ik zie een aptychus of een bivalve.

Groeten,
Oliver
