Hello Joy, I think it's Laevitrigonia sp. Is it from the Portlandian? I don't know Ringstead are very well!

Thanks AlbianPhil and Colin
I am afraid my geology is not up to the scratch, so sorry for not knowing if it is Portlandian. If it makes any sense, I found it at the rocky end of the beach with large flat step-like rocks. I posted an in situ picture of another of these on the in situ thread if that helps. Joydip ![]() Here is a different one, the matrix is greenish and speckled. |

Hi Joydip
That looks like a Neithea gibbosa from the upper greensand.

Thanks Bob
Thanks Andy There were many giant fossil oysters, worm tubes and coral (I think) in the clay. Hope to post some more photos soon. |

I found Ringstead quite disappointing, we only collected a few giant oysters and that was it, looks like you already did better than us, what did you make of the place?
Thanks Dave

Hi Dave
My experience was similar. Although I found a bit more than those ubiquitous oysters, I wasn't impressed. I had hoped to find at least one ammonite in the Kimmeridge clay, but was disappointed. Will post photos of the other finds soon, unfortunately very average ![]() Cheers Joydip |

Joydip I think it's Myophorella - see pictures on google - it's very similar to your example

I agree with the first being Myophorella sp. See www.southampton.ac.uk/~imw/ click on Osmington fossils

Nice, you may know already but the species of the oyster is Deltoideum delta.
Thanks Dave

Yep, D. delta as Dave said. I have a couple with articulated valves from Bowleaze Cove.

Dont know about you Bill but the Bowleaze Cove ones felt a little more robust to me, like they were slightly less likely to fall apart.
Thanks Dave

I agree they're very robust Dave, but can't comment on the ones at Ringstead, never collected there. Though Joydip's specimen looks pretty good.

Having been to both locations id say the Ringstead ones are bigger but are also much more likely to just fall apart. JD, have you ever been to Bowleaze Cove?
Thanks Dave

Hi Dave
I haven't been to Bowleaze Cove yet. Are there many interesting finds to be found there including Deltoideum ? Cheers Joydip |
