Fossil History

 Relative to the huge abundance of fossil records belonging to other families of cerithiids gastropods found, there were relatively few evidences of planaxids in the fossil records (Houbrick 1987). Thus, little is known about the early evolutionary history of the family Planaxidae within the superfamily of Cerithiacea gastropods (Houbrick 1987). The earliest known fossil records of planaxids were dated far back in time, to the Eocene epoch, approximately 55.8 million years ago (MYA) (Houbrick 1987). Among the early planaxids, the genera Planaxis were among the earliest representatives of the Planaxidae family found during the Eocene period (Houbrick 1987). The earliest fossil records of P. sulcatus was first discovered in Sonde (Madioen), Java, Indonesia (Houbrick 1987). The species, P. sulcatus is thought to have first evolved during the Pliocene, approximately 5.3 MYA, when the fossil found in Java was dated back to (Houbrick 1987).

  Geographical timeline depicting the tertiary period. The family Planaxidae was thought to first appear during the Eocene, approximately 55.8 MYA. The genera Planaxis were the earliest representative of the family Planaxidae. The earliest Planaxis sulcatus first evolved in the Pliocene, approximately 5.3 MYS.
