Palatal view of three-dimensional reconstruction of the maxillary bones in early developmental stages of the three-toed sloth Bradypus.

(A) Bradypus variegatus (ZMB 33812), SL = 23 mm; (B) Bradypus variegatus (ZMB 41122), SL = 26 mm; (C) Bradypus variegatus (MNHN-ZM-MO-1995-326A), SL = 26 mm; (D) Bradypus variegatus (MNHN-ZM-MO-1995-326B), SL = 30 mm; (E) Bradypus sp. (MNHN-ZM-MO-1902-325), SL = 30 mm; (F) Bradypus sp. (MNHN-ZM-MO-1995-327), SL = 38 mm. Upper teeth are in violet; premaxillary bone is in red. Dashed lines represent dental alveoli. Abbreviations: b.c., bony crypt.
