But for most goated DINOSAUR, i personally would say either sauropods (more specifically titanosaurs), large ceratopsians, or large tyrannosaurs

I’m going to have to agree with A.A, azhdarchids are among the most successful pterosaurs out there, with some members reaching astonishing sizes and being better suited for a more terrestrial lifestyle. Basically a four-legged stork as tall as a giraffe

nah that goes to mosasaurus for me
its like a shark and whale but better in every single way
