Our research focuses on vertebrate fossils, with the aim of reviewing and updating important information. To do this we rely on a very large bibliographic material with more than 15.000 scientific papers.

On the other hand, we review different museum collections worldwide, in order to obtain new data, which are used in different studies and subsequently, we publish the results in scientific journals and popular books.

Our specialties are:

• Metrology focused on organism and fossils (Osteological measurements, volumetric calculations, specific gravities calculations, body mass and size estimations)
• Skeletal reconstructions
• Phylogeny
• Paleogeography
