Palaeontology of the Bagh beds: Part X—Scaphitidae

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

In an attempt to establish morphologically adjusted relation with rapidly changing environments some of the Bagh ammonoids of Placenticeratid stock have given rise to a variety of heteromorphs, grouped here under a new genusPlacentoscaphites. This group exhibits tendencies (1) to uncoil, retaining the plano-spiral mode of coiling, and (2) to departing from plano-spiral coiling.

In the light of Kauffman’s observations occurrence of these heteromorphs suggests at least three regressive phases in the course of Bagh sedimentation.
