Space-time presentations of the shell of the bivalved mollusk Cardium edule.
In a recent article the concept of studying craniofacial growth in space-time was introduced. The possibilities of carrying out such studies were demonstrated with the aid of some generalized shell of a bivalved mollusk. In this study presentations of space-time models of a real biologic model, the shell of the bivalved mollusk Cardium edule, have been constructed. Quantitative expressions of paths in space-time of anatomic and material points have been elaborated. A further analysis has shown that a number of the space-time presentations may represent biologic reality. They may be used for comparisons with presentations of skull models and may represent a tool for the better understanding of results from other studies.
