LONDON, ENGLAND—Researchers have not been able to determine how nine bones from a large Pacific walrus ended up in a coffin under St. Pancras Railway Station. The bones were found in 2003, during work to expand and refurbish the Victorian-era terminus. Scientists do know that they had been buried with eight sets of human remains in the early nineteenth century. The bones may have been used in medical research or instruction, since they show signs of dissection. The railway station was built in 1868 on top of St. Pancras churchyard.
