No, bigger - how about bovine?
Looks like well weathered bone
How about marine e.g. A bit of whale vertebrae or similar
Looks like bone. Scapula or, a component of a pelvis?
Looks like whale bone. Whalebone is porous like that and full off oil when the whale is alive.Trevor
HM Coastguard blew up a whale using explosives some years ago at Ockle, in the bay by the bothy on the shore. There are still bits of bone to be found there. Perhaps it's a piece of whalebone that's drifted down the coast. Jon
Amanda Clydesdale comments, "It may well be whalebone. I've worked on archaeological whalebone, it has been used for everything from bowls, door pivots, gravestones, loom weights, structural (constructional) elements and even as fuel, because of its high oil/fat content. Might be worth carefully checking for signs of working."
This is definitely a bit of whale bone. I've got some just like it from a Fin Whale washed up in Cumbria. Richard
