Paleontologist prints fossils in 3D Answered
French palaeontologist Paul Tafforeau has been using 3D lithography to make microscopic fossils, hidden in opaque blocks of amber, vsible for detailed study.
Using intense light from a synchrotron (a kind of particle accelerator), he illuminates the amber, revealing, so far, over 350 specimens of trapped insects in 2kg amber. Some of the species are new to science.
3D images are built up with micro-tomography, and these digital images are used to recreate millimetre-scale insects as plastic models at a scale that allows easy handling and visual study without needing microscopes.
