About 453 million years ago, a trilobite might have escaped the claws of a hungry giant sea scorpion. That is according to palaeontologists who analysed an unusual fossil found in the Czech Republic.

Trilobites flourished in the oceans from around 522 million to 252 million years ago before going extinct. These hard-bodied arthropods resembled woodlice and ranged between about 1 millimetre and 70 centimetres in length. About 20,000 trilobite species are known from the fossil record.
