Happisburgh and East Runton

[Pleuromya]

Hi, not too long ago I went to East Runton and Happisburgh in the hopes of finding some fossils, whilst the best time to go is winter, I was happy going in Summer. Apparently, fragmentary Mammoth molars are found commonly at Happisburgh during winter months. I found possibly two bits of mammal bones, possible fossils shells (one was in the clay cliff) and an orange belemnite. Is it possible to identify the bits of bone, or are they too small? 

 

Possible fossil shells

 

Possible bits of bone. The top bit split when I picked it up, unfortunately the split bit then split, so that's just drying now after being glued.

Interesting bits of flint

 

Lastly a bit of flint, I was wondering if it could be a sponge/coral? And a very white bit of stone with kind of layers, as well as two possible fossil shells. 

I'm not sure why the pictures appear smoothened.
