Artistic representation of the opportunistic burrowing behavior of the hypothetical ancestor of crown snakes, as predicted from reconstructed high-definition 3D whole-brain models (highlighted middle right) shown in dorsal (top) and lateral (bottom) views. In comparison, the reconstruction of the first natural endocast of a fossil snake (Dinilysia patagonica, top right) displays a divergent morphological configuration of the telencephalon (Tel) and provides no or limited information about the diencephalon (Dien), mesencephalon (Mes), cerebellum (Cb), and medulla oblongata (MO) regions. In contrast, the estimated endocast of Najash rionegrina (bottom right) shows similarities with the hypothetical ancestor of crown snakes in several distinguishable telencephalic regions, including cerebral hemisphere (CH), olfactory bulb (OB), and olfactory tract (OT). Reconstructions of the fossil skulls (purple color) are shown around the cranial endocasts. Image credit: Macrì et al., doi: 10.1126/sciadv.adi6888 / Neptalí Ramírez Marcial.
