What is it about?
The text presents the case of the three-dimensional documentation, by means of structured light scanning, of a set of twelve dinosaur teeth that are part of the collection of the Natural Science Museum of Álava. The preparation of the 3D models and the dissemination via an open repository, with the aim of increasing the number of references for identification and classification purposes. There are some important challenges regarding the proper documentation since teeth combine meaningful features of very different sizes and, also, because some of these characteristics are of qualitative nature.

Why is it important?
The text highlights the necessary relationship between the features of the 3D models and the type of mathematical analysis that will be done in order to classify or identify the specimens. The traditional classification by expert’s assessment is now under questioned by the analytics methods of automatic classification; however, it is not unusual that the analyses carried out only have incomplete knowledge about, the specimens, the characteristics of the geometric models and the bases of the mathematical tools. All that hinders the achievement of good quality results.
Perspectives
We wanted to merge in this project a wide range of professional for multiple fields: 3D recording (for the generation of the models), palaeontology (knowledge of the pieces), conservator (for the handling of the specimens at the museum) and economists (since we wanted to study to which extend a better outreach of the collection could help to enhance the acknowledge of the museum by the visitors). All that with the aim of linking the scientific and the social impact of the project.
