Using a technique called very high-resolution x-ray computed tomography, researchers at the University of Manchester dissected a 50 million year old spider encased in amber. As reported in Zootaxa, leveraging the same technology used in CAT scans, it can make out features the width of a human hair. In this case, the technique enabled the researchers to identify the critter of Halloween past as a new species.

    I’m so pumped about this technology finally being used on invertebrates! There is so much we can still learn about some of these ancient species.
