22. Mosasaurs, Ichthyosaurs, Pterosaurs, Plesiosaurs, And Dimetrodon
Although Hollywood has done their part to confuse the general public, animals like mosasaurs, ichthyosaurs, pterosaurs, plesiosaurs, and dimetrodon, are actually not dinosaurs. The term “dinosaur” is used to describe the land-dwelling reptiles that lived during the periods described previously, that have a specific hip structure. Yes, it actually all comes down to the hip shape and size, which we will get into later. For some reason, the distinction between these classifications are rarely made.
