New here, so please excuse my ignorance...
My partner and I collect bones, particularly off the beach when on holiday. A couple of years ago we found these two on the shore in the Outer Hebrides, Western Scotland. They have been hung on our wall along with whale, seal, shark etc plus land mammal bones since then, but I dont know what they are! Clearly the long one is a rib, but off what? Is the other bit related maybe...?
Having found them on the shore, I hoped they were Basking Shark or similair, but its recently dawned on me that they could be from, say, a cow, that fell into the sea!
Any ideas folks? The metal rule is 12".
Id love to know what they are, but Im kinda pleased its not just me who is stumped!
The big flat one is symmetrical so Im inclined to think it os located somewhere along the centreline. Iv googled whale skeletons and wondered if it could be the remains of the breast bone where the first set of ribs meet? (Sorry, dont know technical jargon).
I cant see anything on a cow skeleton or similair that looks like it.
Hi, I agree that as it is symetrical it is a midline structure and a sternum (breast bone) is the most likely. The size is quite considerable and would exclude dolphin which leaves larger whales. Your bone appears to be about 2-2.5 times bigger than a dolphin sternum so the whale it is from would be about 7-8m long. This would put it at the size of a pilot, killer, beaked or minke whale.
Looking at both pilot and killer whale skeletons online there is usually a hole in the centre of the sternum which does not show on your bone. This photo of a minke whale skeleton also shows a very different sternum
However, both Cuvier's beaked whale and Beluga whale have a sternum very simillar to yours:-
Beaked whales have been known to strand on the outer isles, the commonest, I believe is the Cuvier's.
I will allow you to make your own mind up and perhaps search for more whale skeletons on line.
