Sérgio and Lionel spent three weeks working in the anteater collections of the British Natural History Museum (BMNH) in London to collect geometric morphometric data. Thanks to a Synthesys program collection grant they were able to use the micro computed tomography (micro-CT) scanner facilities to collect 3D CT-scans of embryos and neonates. Many thanks again to Roberto Portela Miguez & Louise Tomsett (host curators), and Amin Garbout & Farah Ahmed (CT-lab facilities).
