Fig. 4From: Dentition and feeding in Placodontia: tooth replacement in Henodus chelyopsA Boxplots comparing the length (a), the width (b), and the height (c) between both specimens GPIT-PV-30003 and GPIT-PV-30007 of Henodus chelyops and between their replacement and functional teeth. The thick black lines represent the medians. The values are in millimeters. B Bivariate diagrams between the replacement and the functional tooth size in both H. chelyops specimens. The length difference (a) is illustrated at the top, the width difference (b) at the middle and the height difference (c) at the bottom. The values of the teeth of specimen GPIT-PV-30003 are represented by triangles and ones of specimen GPIT-PV-30007 are represented by squares. The values are in millimetersBack to article page
