That is weird looking, a cross between the body plan of a mosasaur and an ichthyosaur. It’s funny that the article talks about how mysterious this creature is and how it didn’t swim like a plesiosaur- but makes no mention of the ichthyosaurs it clearly resembles.
Large predatory sea creatures often end up with streamlined body plans with a dorsal fin. Sharks, dolphins, ichthyosaurs… makes sense that some faster mosasaurs would evolve in that direction too. 72mya is fairly late in the game during the Cretaceous period.
