In the realm of dinosaurs, the duel between Spinosaurus and T-Rex captivates the imagination. These fierce creatures, part of the Tyrannosauridae family, have long fascinated scientists and enthusiasts. This article delves into fifteen key distinctions between these iconic predators, covering aspects like size, locomotion, footprints, speed, skull size, teeth length and shape, bite force, classification, habitat, behavior, diet, and extinction.

In the last post I pointed out some similarities between Davide Bonadonna’s new Spinosaurus painting and Brian Engh’s Spinosaurus *painting from 2010.

UPDATE the next day: Since I published this post, it’s become clear that the similarities in the two images are in fact convergence. Davide Bonadonna got in touch with Mike and me, and he has been very gracious and conciliatory. In fact, he volunteered to let us post the making-of images for his painting, which I will do shortly.
