Fig. 5 in Evaluating the utility of linear measurements to identify isolated tooth loci of extinct Hyracoidea
Fig. 5. Distribution of values for a set of univariate, potentially locus-diagnostic traits (A, length vs. M1 length; B, paraloph vs. metaloph; C, metaloph vs. length; D, paraloph vs. length) described in Fig. 2 in upper molars of a range of hyracoid species.
Fig. 4 in Evaluating the utility of linear measurements to identify isolated tooth loci of extinct Hyracoidea
Fig. 4. Overlap in potentially diagnostic trait values for lower molar loci of three example hyracoid taxa (A1, B1, Procavia capensis; A2, B2, Saghatherium bowni; A3, B3, Thyrohyrax domorictus). A. Length vs. proportional frequency, showing how a single trait, length, would be modeled in a univariate discriminant analysis using observed means and variances. Colored sections of the distributions show length values that are within 95% confidence intervals of the means of more than one tooth locus, indicating regions of ambiguous lengths. B. Length vs. relative width, showing scatter plots overlaid on 2D density diagrams showing the distribution of values for individual teeth.

Figure 1 in Stingray diversification across the end-Cretaceous extinctions
Figure 1. Dated molecular phylogeny of elasmobranchs, with emphasis on stingrays (Myliobatoidei), based on an autocorrelated relaxed clock (TK) analysis of the nuclear and mitochondrial data (excluding third codons). Numbers at nodes are posterior probabilities, node heights are mean estimated ages; the K-Pg extinction (66Ma) is marked with a red line. Stingray clades A-F are discussed in text. Node bars indicate 95% HPDs for stingrays and myliobatids (eagle and manta rays). Images are all public domain and from NOAA except for shark (Tony Ayling), whiptail (Pearson Foresman), stingaree and chimaera (both copyright expired).
