I don't know much about this subject but it seems odd to me that museums of dinosaurs seem to be all over the place. Yet the bones of the dinosaurs in these museums are all replicas. It's like the government decided to convince everyone on the dinosaur story around the same time. Hollywood too got into the dinosaur game and dinosaurs tend to be added to the curriculum at all schools.
Yet despite all this, I've heard reports that the real bones found might not actually be reconstructed in the way in which they have been. Scientists thought the dinosaurs were reptilian like now they think bird-like. Some people think the ones are just from wild animals that existed not so long ago. Like big Lions or Wolves that went extinct.
Have we been lied to about the existence of dinosaurs in the first place?
OP, I once went to this huge dinosaur fossil exhibit. According to the exhibit itself, the alleged bones were unearthed in a very remote part of Utah during the early 20th century where there were no phone lines or mail or any communication outside of the excavation camp. It was financed by a robber baron Bill Gates-like figure. All I could think of when I read that was how convenient it would be to shape whatever narrative they wanted in that situation. Dispose of whatever inconvenient-to-the-narrative evidence they found and make up whatever shit they wanted in its place. So no, I do not believe the official narrative surrounding dinosaurs.
