Fig. 3. Micro-CT-scan 3D model of the palate and neurocranial cavities (preserved as pyrite concretions) of the lungfish Scaumenacia curta (Whiteaves, 1881) (MHNM 04-728A) from the Escuminac Formation, middle Frasnian, Upper Devonian at Miguasha, Quebec, Canada. A. 3D model in dorsal view (A1), interpretative drawing (A2). B. 3D model in ventral view (B1), interpretative drawing (B2). Black lines, dermal bones outlines; red lines, pyrite concretions; pink infilling, interpreted as neurocranial parts.
