Whats this?? From Hunstanton again

I have some lobster burrows that look similar so maybe a burrow of some sort?

cool any ideas what the others are??

Hello Craig,

I'm rather busy at the moment, so I haven't had time to post my finds - but I'll definitely post some this weekend! I'm sorry to disagree but that's almost certainly not a crustacean burrow. It is a sponge, these are relatively common in flint, and if you split them open they will reveal the inner detail. They are easy to spot because they are long and relatively thin, with a hole running down through the middle, often exposed at one end.

Regards,

Joe

It could be joe, those damn things are everywhere though Im not sure thats flint, it looks like pyrite within a phosphoric nodule.

Spleain, Sorry but it is definitely a sponge preserved within flint.


Joe

dont be sorry dude

It's always a tough one disagreeing, or even correcting someone - and in Palaeontology this happens a lot. I know a bit fair about fossils, and I'm normally quite accurate when identifying fossils, this of course gets tougher when you attempt to ID Genus, and Species. However, in this instance I'm certain. But, having said that anybody could always be wrong at anytime.

Joe

Its good to have some good ID'ers on here

Should i split it then??

go for it

It's up to you Craig. If you don't have many then I would consider leaving it, but if you have a few then it would probably be worth a go. Sponges frequently don't just split cleanly in half, they will shatter into many pieces, but it will still reveal the detail within.

Joe

flint does typically shatter if there is no decent fault, if you come down my neck of the woods the ground is pretty much lined with sponge fragments - reasonably unatractive things, though maybe only by abundance - your other sponge craig tho is pretty.

i wont be killing my sponge lol

I would agree, a sponge. They get quite fragile sometimes, not surprising with their age.
