The CT scan of the springtail on the back of the mayfly
18 Oct 2012 Stunning images, including video footage, from a CT scan of amber have revealed the first evidence of any creature using an adult mayfly for transport. Researchers at the University of Manchester say this 16 million-year-old hitchhiker most likely demonstrates activity that is taking place today but has never previously been recorded. Entombed in amber the tiny springtail can be seen resting in a v-shaped depression at the base of one of the mayfly's wings. It appears to have secured itself for transport using its prehensile antennae. David Penney and colleagues from the Faculty of Life Sciences and the School of Materials used a high resolution CT scanner to take over 3,000 X-rays from different angles. The scientists then created slices, showing the fossil in cross sections. From these slices 3D digital images of the springtail were made so an accurate analysis of its behaviour could be conducted.
