A team of researchers led by Dr. Verónica Díez Díaz, postdoctoral researcher at the Humboldt Universität Berlin and the Museum für Naturkunde Berlin, has reconstructed for the first time the three-dimensional musculoskeletal system of the tail of one of the sauropod dinosaurs: Giraffatitan brancai. Thanks to this detailed three-dimensional reconstruction of the tail, the authors have been able to more accurately calculate the probable weight and volume of each muscle, and even hypothesize the total values for the complete tail, weighing ca. 2.5 tonnes. The specimens used for this study are housed at the Museum für Naturkunde Berlin, and all the created digital files are freely available.
