ABSTRACT
Crinoid calyxes were modelled on a computer. Models were generated by 1) setting individual calyx plate shapes and then 2) calculating the geometry imposed on a ring of plates with the modelled morphology. Preliminary results using only three rings, corresponding to the infrabasals, basais, and radiais, show that the model successfully replicates the breadth of calyx designs seen in nature. Analysis of the filling of the morphospace generated suggests that most areas of possible geometry are filled, but that the density of the filling is variable.
