Hunstanton Cretaceous mysteries

[Ossicle]

Mostly my finds from Hunstanton are readily intelligible, but these are some I'm struggling with.

 

Red rock: Hunstanton Formation, Cretaceous, Albian Stage

 

White rock: Ferriby Chalk Formation, Cretaceous, Cenomanian Stage

 

The first are two mysteries from the Hunstanton Formation. As always, any help is greatly appreciated!

And these are the Ferriby Formation puzzles.

Worm tubes.

If you have to research, write "Albian" and "Cenomanian"

Thank you! I've edited plus the tags. That's me typing from scribbles in my notebook, and yes, that really won't aid researching!

 

I've been using Fossils of the Chalk by Smith and Batten for most of the chalk fossils, and I'm less familiar with the Cretaceous chalk, I've only been on a few trips and am just now cataloguing these finds. I'm hoping to make more trips soon.

 

These few didn't quite fit. I think worm tubes are very likely, they're so varied, although I was wondering if the third image might be some kind of ray plate. It's different from the ray plate shown in the book, though.

 

I bet it's a serpulid. When I'm stuck, doesn't matter the geologic period, it's usually some kind of serpulid .

Let's have a sharp well lit close up of the broken end of #1 please. The first one from the Ferriby looks like a bit of shell. Hopefully some experienced locals will come along and give you qualified answers.

[Ossicle]

Thank you, a portion of shell would very much fit that piece. I get thrown by fragments - once I have a relatively complete piece of something in my collection, I can then usually interpret a more fragmentary version correctly.

 

Here are close-ups of the broken end of the first fossil. It's not this green in natural light (I'm using a flash and a light on my USB microscope), it's a very dark reddish brown. But the lights could be bringing out the colour more accurately.

I'm wondering if the second fossil might be some kind of bivalve hinge.

I think that might be it, thank you!

More likely Inoceramus  sp given the locality and a complete bed, is named The Inoceramus bed, which is packed with comminuted parts of the bivalve.

 

Thanks
