EXTENSION OF THE DEADLINE FOR EARLY REGISTRATION WITH REDUCED FEE: NOVEMBER 30, 2015!
This workshop aims to give the participants the ability to use the interdisciplinary approach of biomechanics, especially (but not only) through examples in palaeontology. Simple models based on the basic principles of classical physics will be used to infer the life history of extinct vertebrates.
