During the aerial bombing of London during World War Two many of the city’s treasures were moved out of London for safekeeping.

One of the world’s rarest skeletons was sent from the Grant Museum of Zoology to Bangor. The skeleton was of the extinct Quagga, which had the appearance of being half-zebra and half-horse, had died out in 1872.

The skeleton was sent to Bangor University but on its return the museum found one of the limbs was missing and its whereabouts remain a mystery.

Tannis Davidson, who is curator at the museum which is part of University College London, said when it was first sent to Bangor, Gwynedd, no-one realised it was a Quagga. That only came to light in 1972, Until then it was thought to simply be a zebra or a horse.

“It is one of many mysteries here,” Ms Davidson told the BBC, “Every specimen in the collection has an interesting mystery about how it got here.

“It would have been used by students as a zebra from 1940 to 1972 when it was identified as a Quagga.”

She has now urged anyone who thought they might have the missing leg to get in touch. “Not that I want to receive 50,000 random horse legs,” she said.

“If this was a crime caper I would definitely follow up this Welsh lead,” Ms Davidson added.

But when BBC Wales called Bangor University they were unable to locate the runaway leg.

Senior biology lecturer Rosanna Robinson is museum curator at Bangor University’s school of natural sciences. She said: “We wish we could give this story legs.

“But the extensive catalogue of our Brambell Natural History Museum has not thrown up any ‘horse’ limbs which shouldn’t be there, so the trail has gone cold at our end.”

Ms Davidson hopes the riddle might yet be solved – though the skeleton is also missing a shoulder bone.

“It is a long-standing mystery and to have the rarest skeleton in the world fully completed again would be fabulous,” she said.

  • They were stronger on the head and neck, gradually fading behind the shoulder.
  • A broad stripe ran down the middle of its back
  • The underside of its body, its legs, and its tail were nearly white
  • The last one died at London Zoo in 1872
