From: Histological evidence for a dynamic dental battery in hadrosaurid dinosaurs
Zones of alveolar bone within the adult (UALVP 56336) and perinatal (54419) hadrosaurid dental batteries, all in transverse view. (a) whole section of the adult dental battery; (b) magnified image of Zone 1; (c) magnified image of Zone 2; (d) magnified image of the box in (c); (e) magnified image of Zone 3; (f) magnified image of Zone 4; (g) whole section of the perinatal dental battery; (h) magnified view of the box in (g). Black arrows indicate direction of net movement of alveolar septum. ant, anterior; as, apposition side; hl, Howship’s lacunae; ling, lingual; post, posterior; rs, resorbing side.
