There is an on-going lively debate on the kind of metabolism and possible thermal strains in dinosaurs, especially in large sauropods. To gain comprehensive and innovative insights into the thermoregulation and overall thermal constraints of these large, extinct organisms, we intend to employ a systems biology approach by linking empirical research with biophysical knowledge and computer modelling. To reach this goal, (1) state-of-the-art technology (telemetry, telemetry sensors, heat flux sensors, infra-red camera, 3D laser scanner) as well as advanced mathematical software will be used to describe, quantify, and analyze the thermophysiology of the largest terrestrial organism living today; i.e., the elephant, which can reach a body mass comparable to a small/medium sized sauropod. (2) Based on these results sophisticated mathematical models will be developed, (3) which will be implemented into already existing 3D body mass models of prosauropods and sauropods, to finally (4) improve the qualitative and quantitative understanding of the thermoregulative dynamics of these extinct species by simulating their thermoregulative processes under various environmental conditions and different levels of activity-related thermogenesis.
