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?
Ever read forensic files or police reports for remains that were discovered many years after death? Very rarely do they ever find a complete skeleton. Why is this? Because of things like weather, erosion, and animals that carry off pieces of the bodies. Same thing applies in nature. Ever gone out hunting and come across an old skull of a deer or elk. Chances are high that little else remained (it has happened to me many times). Add thousands or even millions of years into the mix, and the bones become fossilized. That makes them much harder to distinguish from the surroundings, and harder to locate.
