Kulbeckia is an extinct monotypic genus of zalambdalestid mammal that lived in Central Asia from the Turonian to the Santonian stages of the Late Cretaceous epoch.

Description

Kulbeckia kulbecke shows significant intraspecific variation in how many premolars it possesses. Some individuals never lose their dP³ and dP₃ because it never gets replaced, while others lack enough space in their tooth row to develop the third premolars.
