Table 1. External and cranial morphological measurements (mm) of Typhlomys .
Variable | T. cinereus(n=2) | T. daloushanensis(n=29) | T. chapensis(n=21) | T. nanus(n=3) | T. sp. 1(n=9) |
TL: Tail length; HB: Head and body length; HL: Hind foot length; EL: Ear length; WG: Weight; GLS: Greatest length of skull; CBL: Condylobasal length; BL: Basal length; IOB: Interorbital breadth; BCH: Braincase height; ZMW: Zygomatic width; UML: Upper molar row length; LUIM: Length between upper incisor and molar; M1-M1: Crown breadth of 1st upper molars; HCV: Height of coronoid valley; LNM-FLM: Length between backmost notch point of mandibular and front of lower molars. External and cranial morphological measurements of cheek teeth of above species were obtained from Cheng et al. (2017), except for T. sp. 1. | |||||
