Text-fig. 7. Enamel microstructure in the molars of (a) Allosorex stenodus (KOE-4196 / Z 28207 – OF 6512) and (b) Blarina brevicauda (KOE-1435). SEM photos showing transverse sections of the paralophid in a lower molar. The schmelzmuster of Allosorex is one-layered and formed exclusively from radial enamel (RE), whereas the schmelzmuster of Blarina is two-layered, with an inner enamel of laterally inclined radial enamel with distinct interrow sheets (REIS). The radial enamel of the outer layer is heavily pigmented and therefore poorly etched. The pigmentation does not affect the schmelzmuster. in Allosorex Stenodus Fejfar, 1966 (Eulipotyphla, Soricidae): Re-Description Of Type Material And Re-Interpretation Of Its Fossil Record
