Figure 2. Natural logarithm of length*width on M1 of Siwalik murine rodents.

Figure 2

Length was measured on the longitudinal axis of the tooth, which is parallel to the dotted line connecting two reference points on the labial side of the tooth, as in [53]. Symbols: 14.1 Ma, green cross for “near Antemus”; 13.8 to 12.8 Ma, inverted orange triangle for Antemus chinjiensis; 12.4 Ma, purple diamond for “near Progonomys”; 12.3 Ma, purple diamond for Progonomys sp.; 11.6 to 11.2 Ma, blue circle for ?Karnimata, purple diamond for Progonomys hussaini; 10.5 to 10.1 Ma, blue circle for Karnimata sp., red triangle for Progonomys sp.; 10.5 Ma, orange cross for morphotype 1; 10.1 Ma, orange cross for morphotype 2; 9.4 to 9.0 Ma, black diamond for Parapodemus sp., blue circle for K. darwini red triangle for P. debruijni; 8.8 to 8.2 Ma, blue circle for Karnimata sp. (+large Karnimata sp.), red triangle for Progonomys sp., orange x for morphotype 4, green asterisk for morphotype 7; 8.0 to 7.1 Ma, light blue square for Parapelomys sp., blue circle for Karnimata sp., purple cross for morphotype 8, black x for morphotype 4, red triangle for Progonomys sp. green diamond for Mus sp.; 6.5 Ma, light blue square for Parapelomys robertsi, blue circle for K. huxleyi, red triangle for M. auctor. Three samples of Karnimata sp. at 7.4 Ma which were grouped with Karnimata sp. at 8.2 Ma are circled.
