HI Just tidying up a few bits from Cayton Bay (South) and thought I'd post.
This is the first one I have done...thought it was Posidonia but it kept growing lengthways as I uncovered it. Resembles a razor clam with a flattened or grooved piece down one length.
First time for me at Cayton so I don't know what to expect....anyone seen this before?

Hi

Has feature similar to Modiolus, not sure, someone may confirm or have other ideas.

Hi Robert and Janet - just checked the geology and Modiolus is a bit older than this one (Middle Jurassic), so I would go for Myoconchia crassa.

Thanks all for comments. I don't have a clue on this area myself. I have other finds and will post when I clean up the samples. The sandstone/shale is extremely friable

THX again Colin. Had a chunk of similar friable material with small shells unfortunately cannot clean them up to get a decent photo...they just crumble to dust. Do you think Cayton Bay deposits must have been laid down in beach lagoon with a river running into it occasional flooding laying down the mud that intersperses the sand.

I have this though that I picked up at Kettleness a few weeks ago...again lots of tiny shells but at least they are stable in the slate. Do you have any idea what they are? IMG_20190329_143043.jpg  IMG_20190329_143129.jpg

Hello Robert, it soun!s like you need to investigate the area in a bit of detail if you intend to go back! The screenshot below may help a bit but it is not complete so  suggest you consult a geological map and publications about the strata of the area - can't say too much more![wink]

Remember your matrx may come from a dfferent strata.
