FIG. 7 in New diminutive Eocene lizard reveals high K-Pg survivorship and taxonomic diversity of stem xenosaurs in North America
FIG. 7. Relation between maxillary tooth length and snout-vent length (SVL) in iguanid lizards (log-log space). Ordinary least squares regression was used to predict SVL from tooth length. Iguanid lizards were preferred to anguimorphs because the broad spectrum of body size covered by available skeletons did not require extrapolation. Red dot represents prediction for USNM PAL 768729.
