Most Relevant Dinosaur Discoveries of the Decade

[Concavenator]

I think it would be interesting to know your opinion regarding which new dinosaur genuses described in the 2010-2020 decade have been the most important / impactful. In that decade, there have been important discoveries concering some already known dinosaurs, such as the colors of some dinosaurs (Sinosauropteryx, Psittacosaurus, Microraptor...) or new findings of taxa like Deinocheirus and Spinosaurus that were previously very little known. These clearly have been important discoveries, but if you could only name 5, which new dinosaur species do you think have had the biggest impact or have been more relevant?

Off the top of my head, I would say Yi, Chilesaurus, Borealopelta, Kulindadromeus and Yutyrannus

Wonderful thread idea!

The discovery of Yutyrannus marked the idea of feathers on large therapods. Also, my favorite dinosaur

Spinosaurus tail and quadrupedal debate. This was definitely a mass produced genus for the last few years, not complaining though.

Patagotitan, possibly largest sauropod?

Like you mentioned, Borealopelta and Yi being my other two picks.

Colour is far from the only thing we learned about Microraptor, and I think if we were to include all new* discoveries relating to each animal as one example, rather than individual discoveries per se, that Microraptor should probably take home first place.

That we can now for the first time say we know almost everything possible about a dinosaur, from its colour, to its diet, to even its moulting patterns, to say nothing of putting to rest solidly the idea of the gliding dinosaur, and by extension it's confusing muddling of the origins of bird flight, says a lot about how far and fast methodologies of the field are improving.

*Newly proven might be more apt, as some of us have been saying Microraptor flew since the early wind tunnel studies showed it gained lift at speed, even though the various authors always tried very hard to fight against that conclusion...

i'm not well versed enough to make an intelligent comment on this but I can comment on what is to me personally impactful.  Borealopelta and, not sure when first discovered but titanosaur nesting sites, several of which have been found in south America, asia and Europe.  And finally, while this has been known for more than a decade, the fact that some dinosaurs lived in relatively cold weather climates, as driven home by Yutyrannus and Nanuqsaurus.

Spinosaurus(new feautures)
Yutyrannus(feautures)
Borealpelta(colors)
Psittacosaurus(c)
Deinocherius(nf)
Brontosaurus(revival)
Edmontosaurus( new features and colors)
sorry if i got dates wrong

Interesting choices by you all, but I was referring to new species. That would leave new findings about Microraptor, Spinosaurus, Deinocheirus and so on out of the question.

I was thinking of including Patagotitan, but Dreadnoughtus was also considered to be the biggest dinosaur back when it was announced. I don't think that "the biggest something" has much interest aside from that. It seems that every now and then a particularly large sauropod is discovered. I wouldn't be surprised if paleontologists found fossils of a sauropod even bigger than Patagotitan.
