Another Dinosaur That May Have Never Existed: https://fivethirtyeight.com/features/the-biggest-dinosaur-in-history-may-never-have-existed/

I saw a blurb of people a few years ago claiming that dinosaurs never existed - one other problem they brought up is that a full skeleton of a dinosaur has never been found, which was only coincidentally found last year allegedly (after people were complaining about a full model not having been found): https://www.forbes.com/sites/davidbressan/2020/08/28/150-years-after-its-discovery-the-first-complete-dinosaur-skeleton-ever-found-has-finally-been-studied-in-detail/

Some other issues brought up:

Dinosaur bones only apparently started being found in the 19th century coincidentally around the time the theory of evolution was being promoted

A lot of the models on display allegedly in museums are reconstructions and plasters, with the actual bones being kept archived

According to this link: https://www.quora.com/How-many-dinosaur-fossils-have-humans-found

"only about 3,000 full dinosaur skeletons or skulls in museums [in the U.S.], and only about 12,000 total discovered around the world."

What do you think of dinosaurs and our current understanding of them?
