What about Jack Horner? He has his own bones. Drilled into them, cut them open, noticed some things, like how what scientists thought was a different species of dinosaur was actually a juvenile version. The Triceratops isn't the adult, he thinks Styracosaurus is the completed adult due to the grain of the bones, how not fully adult bones appear different than fully adult. He was able to cut into the bones because they're his, scientists are obviously handtied and guessing with whatever they have access to. Jack did a speech on it, it's probably on Youtube, who knows what else he has discovered since then. Atheist scientists are always inflating the number of species in their categorization, but categorization itself isn't "science" it's a logical system devised by Linnaeus. It's a good way to identify things due to the practical limitations of the human mind, but the whole "this became this new species" is abstract, especially with extinct animals.
