Fig. 3: Premolars and molars develop through two different cascades and are lost differentially as jaw length decreases.

a Reconstruction of the developing dental lamina in our four morphogroups of bats on µCT scans. Permanent premolars are indicated in green, deciduous premolars in yellow and molars in pink. Premolars and molars develop in two different directions, as the dental lamina grows and matures. Scale bar: 500 µm. b Gradual loss of dP3/P3 relative to adult jaw length. µCT slides of the different premolars are represented around CS23 for the different groups. The relative jaw length of adult bats is represented on the right, illustrating the relationship between tooth number during development and adult jaw length. Species represented in these µCT scan are in bold, others can be found in Supplementary Fig. 6. P posterior, A anterior, Li Lingual, La Labial. Each measure was taken three times. Source data are available in Source Data File 1 and 2. Detailed morphogroups are indicated in (b).
