Reconstruction reveals fossil's tethered young

Palaeontologists have reconstructed the fossil of a 430 million-year-old sea creature which apparently dragged its offspring around on strings like kites.

This bizarre behaviour is not seen anywhere else in the animal kingdom.

Writing in the journal PNAS, the palaeontologists who discovered it have dubbed the fossil the "kite runner".

Ten capsules tethered to its back appear to contain juvenile progeny, all at different stages of development.
