T.rex vs Spinosaurus aegyptiacus by ddinodan_

[u/Hopeful_Lychee_9691]

ddinodan_ presents a striking comparison between the famous Spinosaurus aegyptiacus and the newly discovered Tylosaurus rex. The artist playfully notes that Tylosaurus rex and Tyrannosaurus rex share the same mythical acronym: "T. rex".

Beyond the joke, the superimposition of the two images is superb and highlights the immense size of this mosasaurid compared to one of the largest carnivorous theropods. Obviously, they never crossed paths (and fortunately for Spinosaurus, given the size of Tylosaurus's jaws). A great way to celebrate this new discovery with humor.

Is the new Tylosaurus rex bigger than Mosasaurus hoffmani?

They would have been similar in length (40-43 feet), but M. hoffmani is only known from cranial material, so restorations of its postcranial morphology are conjectural.
