The motivation of this work is substantiated by the growing interest in bio-structures, that is structures optimised by nature in the process of functional adaptation to fulfil their roles. Bone is regarded to fulfil two major roles: a metabolic (reservoir for calcium and phosphates) and a mechanical one. The mechanical function becomes dominant especially when the skeleton is heavily loaded due to extraordinary body mass, like in case of the sauropod dinosaurs. They were typically one magnitude larger than any other land animal, living or extinct. This sheer size leads to effects in their biology and physiology that are not yet fully understood [1]. The histological investigation of sauropod dinosaurs in comparison with modern species [2][3] supports the view that the giants were warm blooded, fast growing and agile animals, which stays in contradiction with their mass. The calculations of Hokkanen [4] show the size limit of terrestrial animal due to bone strength matches exactly the size of sauropod dinosaurs (100 tonnes). Further he showed that being at this limit is related to muscle power, which is directly translated into dynamics of the movement.
