@smoran could you please confirm?

@bill-heim would you confirm the sp. I could not match it with the root root of G.Gangeticus upper lateral tooth.

Blacktip shark C. limbatus

looks like coral but I can’t say much more.

Sand dollar?

no @bo-nichol

Looks like a sand dollar

it does not match with the anatomy of sand dollar @mazie-ancic

if it is a sand dollar,it should have at least ‘Lunule’ and ‘Peristome’

not a sand dollar at all. it is probably coral

although it is suspiciously bonelike

Possibly a fish spine

i argee with that

same

Fossil stingray barb?

the base attachment is confusing. it looks as if it was a spine made of bone that was integrated into a vertebrate’s body. not sure crabs have that in their claw articulation. and stingrays supposedly have detachable barbs, instead of something that appears to be permanently attached like so

I’m gonna do a spot of research, I’d like to get back to this fossil as it’s grabbed my attention

@leonardo-miranda the specimen has been cleaned further so that the basal part could be visualized properly. Upon cleaning a hooked base with an area of articulation is revealed, which draws my attention in favour of a left lower crab claw. Few more recent photos are attached that may help you to conclude. Thank you.
