Fig. 8 in Carnassiform notches improve the functional efficiency of bat molar shearing crests

Fig. 8. Lower molars of Recent phyllostomid bats. A. Lophostoma silvicolum D'Orbigny, 1836, (USNM 335113) from Panama. Lower molars in anterolabial view (A1), showing deep carnassiform notches in the cristids obliqua of m1–m2 and a weaker notch in m3 (arrows); in posterolabial view (A2), showing deep carnassiform notches in the postcristids of m1–m2 (arrows); in occlusal view (A3, stereopair), showing notches and associated accessory troughs in the talonid basins (arrows). B. Phyllostomus elongatus (Geoffroy, 1810) (USNM 388796) from Venezuela. Lower molars in anterolabial view B1), showing absent to incipient cristid obliqua notches on m1–m2; posterolabial view (B2), showing weak carnassiform notches on the postcristids in m1–m2 (arrows); occlusal view (B3, stereopair), showing the deep accessory troughs adjacent to both the cristids obliqua and postcristids in the talonid basins of m1–m2 (arrows).
