Taphonomy of a clypeasteroid echinoid using a new quasimetric approach [PDF]

Acta Palaeontologica Polonica, 2016
A new quasimetric approach is used to statistically analyze taphonomic data from a commonly occurring shallow water clypeasteroid echinoid in order to obtain metric equivalent measurements of taphonomic alteration on an interval-like scale.
