Scary ancient spiders revealed in 3D models, thanks to new imaging technique. Early relatives of spiders that lived around 300 million years ago are revealed in new three-dimensional models - Imperial College London News Release - Under Strict Embargo - Wednesday 05 August 2009 - 00.01 (BST) Early relatives of spiders that lived around 300 million years ago are revealed in new three-dimensional models, in research published today in the journal Biology Letters. Scientists at Imperial College London have created detailed 3D computer models of two fossilised specimens of ancient creatures called Cryptomartus hindi and Eophrynus prestvicii, closely related to modern-day spiders. The study reveals some of the physical traits that helped them to hunt for prey and evade predators. The researchers created their images by using a CT scanning device, which enabled them to take 3,000 x-rays of each fossil. These x-rays were then compiled into precise 3D models, using custom-designed software. Both Cryptomartus hindi and Eophrynus prestivicii were around the size of a 50 pence piece and they roamed the Earth during the Carboniferous period, 359 - 299 million years ago.
