help id-ing some Whitby bivalves

[mr.cheese]

Hi, I have come across a few different bivalves and my googling hasn't come up with much! I think the heavily prepped one that has no matrix might be Dacryomya Ovum? Not sure though as this is from a single image in google!

Also any idea what the little babies in the back of the matrix might be?

They all came from the same man who picks and preps Whitby stuff himself so pretty sure that is where they are all from.

Thank you and fingers crossed!

Post no.1: Pseudopecten equivalvis. 
I think the small costate shells are rhynchonellid brachiopods, judging from the symmetry.

 

No. 2: Also P. equivalvis

 

No. 3 Pholadomya, not sure of species.

Yes, the little 'uns are rhynchonellids, maybe Calcirhynchia sp. 

 

None of these look like Nuculana (Praesaccella) ovum, (which was Dacryomya ovum) which is much smaller. 

And not Ovum with a capital "O". Species names are never capitalized and the binomial name should be italicized or underlined.

Thank you once again for the lesson!
