Fig. 1.

Fossil anole lizards preserved in amber. Some of the fossils in this study are exceptionally well preserved (A–C). From X-ray micro-CT scanning, the skeleton can be reconstructed in 3D, revealing complete skeletons (B), fully articulated skulls (C), and fragments (D). The external surface of the lizard is sometimes outlined in the amber by air-filled voids, which when reconstructed in 3D reveal details of the body scales (D) and subdigital lamellae (E, Center). Scale detail is also visible through the amber (E, Left and Right). The amber fossils are represented by letters corresponding to those in Fig. 2. Animations of the 3D reconstructed fossils are in Movie S1.
