I did something similar a while ago in a Discord chat, we were discussing how newer dinosaurs that were discovered within the past, like, 50 years would start to become mainstays in popular culture. We even made a chart (with wrestling terminology lol) to describe it:
Main Events: These are the most famous ones. Apatosaurus and Brontosaurus can be merged together (even though they're separate species) but these ten are the ones everybody knows in some capacity.
Upper Midcard: These are usually the ones you'll see in like, 90% of dinosaur documentaries or media but don't have that global recognition that the first ten do.
Lower Midcard: Same as above, but on a lesser scale of memorability. A few have managed to break into the mainstream, but they still mostly exist in dedicated, nature-focused media.
Respectable Obscurities: This is the tier that started the whole discussion: people were talking about how there always used to be obscure and weird dinosaurs in books you'd read as a kid that'd stick with you like Kentrosuaurs and we realized that they kind of always remained these "only-cool-kids-remember" types. These are the ones that dinosaur kids from back in the 90's/2000's might remember.
Virtually Unknowns: Finally, these are the ones that are simultaneously the
most mainstream, but also the most obscure of the mainstream, if that makes sense. These are "newer" dinosaurs for the most part that have featured in things like Jurassic World or in modern kid's books, names that dinosaur nerds will recognize right away but the general public probably doesn't have any idea about.
I'm sure there's a few we missed, but it's pretty crazy just how small the "mainstream" dinosaur recognition is compared to the vast number of species that have been discovered over the years. There were hundreds more in this tier list that most of us didn't even recognize.
