Lisowicia was a truly giant for its time, but not as heavy as initially proposed... This model was used to obtain a plausible body mass estimate. The analysis puts its weight at "just" 5.88 tons (the original value of 9.33 tons overestimates the weight of about 60%). Concerning the scene, YES,I known... Lisowicia and a theropod, again?? :D In my defense, I will say I did this image when there weren't already other similar illustrations, it's a sort of artistic convergence.
