Study draws 'virtual harvestmen'
Scientists have used CT scans to make 3D models of fossil harvestmen, revealing just how little these spindly invertebrates have changed in 300 million years.
The X-ray technique allows the researchers to virtually extract the organism from its encapsulating rock and then study key anatomical features on a computer screen.
This creature, Macrogyion cronos, is distinguished here by its long legs, one of which has a big curve.
Modern relatives have a very similar appearance and use these looped structures to grab on to leaf parts as they move through foliage.
