Microwear on cichlid teeth. (a,b) Dentary teeth of Haplochromis and Neochromis. The 300 µm field of view sampled for two-dimensional microwear data is shown; box shows area of three-dimensional data sample. (a) Macrophyte scraping Haplochromis ‘purple yellow’ (specimen HpyV01). (b) Rock scraping Neochromis gigas (specimen NgR92). (c–j) Lower pharyngeal jaw teeth of Astatoreochromis alluaudi. (c–f) Specimen RMNH.PISC.37865, laboratory-raised, soft food diet; (e) area sampled for three-dimensional microtextural data (boxed in (d)), (f) shows three-dimensional data, 60° tilt. (g–j) Specimen RMNH.PISC.37870, wild-caught, mollusc diet; (i) shows area sampled for three-dimensional microtextural data (boxed in (h)), (j) three-dimensional data, 60° tilt. (a–d,g,h) Scanning electron micrographs; (f,j) Alicona-rendered three-dimensional data. (e,f,i,j) Field of view 145 µm wide; vertical colour scale from 9 to −16 µm.
