The St Pancras walrus

Thanks to Well Behaved Orphan (You can't beat a good education - Lord Bonkers) for his or her comment drawing this story from The Times to my attention:

Archaeologists exploring a graveyard at St Pancras stumbled across a coffin containing a mysterious set of bones. They were later identified as belonging to a walrus. An explanation for the animal's dignified burial has not yet surfaced.

The new St Pancras Church on the Euston Road, as I understand it, has a crypt but no graveyard. Which suggests that the report is talking about Old St Pancras.
