I was given this rock years ago but with no provenance. I have always assumed it is from the Bone Bed - perhaps from Aust or another Severn location. Can anyone tell me the source, and are there any fossils visible? Many thanks. 

The rock is 6cm wide

I think it is bonded in the fourth photo you can see a fish tooth/scale it does look like Aust bonebed but that cannot be said with certainty

Hi Richard,
Typical Aust/Sedbury Rhaetic bone bed. Indeterminate bone, coprolites, fish teeth, phosphate nodules and lumps of Blue Anchor formation in a calcareous sandy matrix. Looks typical of whats left after someones beaten the crap out of a big lump and made off with the good stuff.....
Cheers

Thanks Rob Gary and Pete.
Gary I don't know the term 'bonded' what does it mean? BTW good to see you are still posting!
Pete I like your graphic description of the source! Are you describing what you see in my photos or simply stating the nature of the bone bed.

I think Gary is referring to the matrix 'bonding' the various clasts together and yes I'm describing your rock which is typical of the basal conglomeratic bonebed at Aust/Sedbury. Get your hand lens out and you should be able to differentiate between the components. That Blue Anchor clast in pic 4 is particularly interesting, may well be a rip up clast.
