Fig. 8 in A Possible Heptaxodontine and Other Caviidan Rodents from the Quaternary of Jamaica

Fig. 8. Hemimandible of Xaymaca fulvopulvis AMNHM 268011 (holotype), stereopair of occlusal aspect, coated to emphasize surface textures (cf. fig. 9). Shallow groove crosscutting lingual moiety of p4's occlusal surface is evidently due to wear; it is not a fracture surface (see text).
