Which species do you consider most popular? Because aside from T-rex, the dinosaurs that immediately come to my mind are jurassic. Diplodocus, other sauropods, stegosaurus, allosairus, ceratosaurus... it's been some time since I left my childhood dinosaur obsession so I might remember it wrong tho.

r/Paleontology on Reddit: Why is the Jurassic period the one most popularly associated with dinosaurs, when most of the most recognizable dinosaur species are from the Cretaceous?
April 23, 2024 -

I know the easy answer is "Jurassic Park," but that's just begging the question, since clearly Jurassic Park also got the idea from somewhere that Jurassic = dinosaurs, even though most of the species in the film/book are also Cretaceous species.

The most plausible answer I can come up with with no historical backing is that it's because Mary Anning and the other early paleontologists who founded the field in the early 1800s were digging primarily in Jurassic sites, so most of the finds that entered the public consciousness were Jurassic species, and that name just kind of stuck in people's minds as a synecdoche for the genera of animals being found. Is this the case, or is there more at play to the story that I'm not aware of?
