Paper Abstract

Technology provides an important means for studying the biology of extinct animals. Skeletons of these species must be constructed virtually by scanning in data for individual bones and building virtual models for each. These then are used to produce prototypes of each of the bones at varying scales, allowing the construction of a starter skeleton configuration and the analysis of movement along each joint. The individual virtual bones are then assembled into a starter virtual skeleton using digitized landmark points on the starter physical skeleton to help place them in three-dimensional space. This virtual skeleton is then modified and improved by analyzing the movement at each joint, using the prototype bones. Once this is done, the movement is constrained further by doing animations of the whole skeleton and noting areas of impossible overlap between bones and unreasonable movement. The problems are corrected and new animations attempted until the movement is perfected. This provides a means for understanding locomotion and mastication in these extinct animals.
