Persian Trident bats
The noseleaf has three vertical pointed processes which project from the upper border and a smaller median projection which is situated below them (Fig. 109, Tper1). A small transverse bony spicule projects from the base of the second phalanx of the fourth finger on each wing (Tper2). The ears have a marked indentation on their medial borders below the tips. The lumbar vertebrae are fused. The skull is elongated and narrow, the rostrum well developed, more than half as long as the braincase and almost as deep (Fig. 106). The zygomatic arches have a conspicuous dorsal expansion posteriorly. The upper incisor (I2) is noticeably bifid and the upper canine has a secondary cusp which is almost half the height of the principal one (Fig. 106). The small upper premolar (PM2) is present (Fig. 107).
