Fig. 1 in The Deuterium Abundance in the Local Interstellar Medium

Fig. 1. Measurements used to calculate hypsodonty index (HI) in Megalonyx. HI is calculated as the depth of the mandible (DM), usually measured below the third molariform tooth (see B), divided by the length of the tooth row (LTR; see A), and multiplied by 100. Specimen displayed is AMNH F:AM 99187—mandible of Megalonyx wheatleyi from the middle Irvingtonian McLeod Mine, Florida, in occlusal (A) and lateral (B) views.
