I can remember as a child growing up in the 50’s a fascination I had with reading paleontological books. The dinosaurs the “scientists” wrote about then no longer exist. New dinosaurs have emerged. Even the prehistoric men they re-created were from such minuscule fragments of bone as to qualify more for fraud than science. This is a field notorious for their acrobatics if not their science.

I guess you are talking about the Brontosaurs, now called Apatosaurs. They still exist, but for reasons of biological classification they changed the name. This happens today with well known existing species.

When I was a kid the Panda Bears were considered a separate family of carnivores, along with the Lesser Pandas. These days they seem to group the Lesser Pandas with the Raccoon family, and consider Greater Pandas more closely related to other bears.
