The debate on the dinosaur king of predators reignites. An eight-ton spinosaurus would have been less dense than a 500-gram chicken.
The bones of the spinosaurus were among the densest and most compact in the entire animal kingdom and probably served as ballast to facilitate its diving for hunting. The new study claims that the statistical method and data used were imprecise and inappropriate, so much so as to invalidate the results obtained, and for this reason indicates new guidelines for future research.
