Fossils from Brean Down, Somerset

[Yuanls]

I was at Brean Down on the Somerset coast of England last week, and found various fossils on the beach there. From what it appears, most of the samples I have are from the black rock limestone of the Carboniferous period, although others are differently coloured. They may come from other parts of the coast via longshore drift, or from a point higher up in the cliff, where there are mudstones and sandstones from the upper Carboniferous. 

 

Some banded samples, although I have the suspicion at least one of them is actually striped flint. 

 

Are these some kind of burrow, or is it coral?

 

Is this coral? (front and back images)

I found a large stone, there are 2 shells of some kind and what I think is an echinoid. 

 

I also found a fossil in the cliff face itself, is this a type of coral? It's about 5-6cm in diameter

 

Cheers, I look forwards to hearing from you

Stating the size of the coral

Neat finds!  

 

I'd probably be comfortable with your guess that these are coral. I think your possible echinoid may also be coral, judging by what appear to me to be defined septae.
