Update to Regaliceratops

Summary
The horned, ceratopsid dinosaurs can be easily split into two major
groups based on their cranial structures, but now a new discovery
shows that at least one genus ‘switched sides’ and convergently
evolved the form of the other clade.

Methods for size reconstruction in distorted and damaged vertebrae of
fossil tetrapods.
Paleontological Journal 49(3): 293-303

The methods for reconstruction of the initial dimensions of distorted
and damaged vertebrae in fossil tetrapods are elaborated and tested,
using the axial skeleton of horned dinosaurs from the Upper Cretaceous
of Mongolia as an example. These methods allow not only more reliable
resolution of the problems of vertebrae preservation for processing
morphometric data, but also improvement of reconstructions of the
vertebral column, as skeletons are mounted for museum exposition.
