NEW DATA ON MIDDLE JURASSIC - LOWER CRETACEOUS BELEMNOTHEUTIDAE FROM RUSSIA. WHAT CAN SHELL TELL ABOUT THE ANIMAL AND ITS MODE OF LIFE

Abstract

We present a new data on middle Jurassic - early Cretaceous coleoids family Belemnotheutidae form Russia. The palaeobiogeographic distribution of the family is summarized herein and new palaeobiogeographic data are connected within stratigraphic distribution. Based on well-preserved shells and soft bodies, the reconstruction of soft body structure of Belemnotheutidae has been completed in relation to recent coleoid families. The Belemnotheutidae mode of life and other ecological aspects are discussed in relation to recent coleoid ecology and taphonomy.
