Fig. 9 in Carnassiform notches improve the functional efficiency of bat molar shearing crests

Fig. 9. Molars of Recent phyllostomid bats, showing carnassiform notches and accessory troughs in the talonid basins of m1 and m2. A. Glyphonycteris daviesi (Hill, 1964) (USNM 364266) from Peru. Right lower molars in anterolabial view (A1) showing the notches in the cristids obliqua (arrows; note that the entoconids are partly visible in the background immediately behind the cristid obliqua notch in each molar); posterolabial view (A2) showing the notches in the postcristids (arrows), and occlusal view (A3, stereopair) showing the talonid notches and adjacent troughs (arrows). Note also the carnassial notch and slit in the mesiodistally-oriented paracristid of the m1 trigonid. B. Trinycteris nicefori (Sanborn, 1949) (AMNH 184558) from Panama. Left lower molars in anterolabial view (B1) showing carnassiform notches in the cristids obliqua of m1–m2, entoconid in background partly obscures the notch in m1, and occlusal view (B2, stereopair) showing carnassiform notches and accessory troughs in m1–m2 (arrows).
