a TEM image of the formative site showing the formation of the short rostral rod in G, the formation of the subrostral portion of the socket in F, the formation of the socket in E and the formation of teeth in B1. Note the canals (chB2–D) that connect inferior developmental stages to the outer surface. b Formation of the rostral part of the socket in E. c Adrostral rod of G surmounted by F2.
