Chicken Embryo

10-day-old chicken embryo in a test tube, part of Hans Larsson's study at McGill University. His study involving manipulating embryonic development and turning the chickens into dinosaurs.

Yes, it was based off the Jurassic Park idea. But Larsson said, "It's a demonstration of evolution. If I can demonstrate clearly that the potential for dinosaur anatomical development exists in birds, then it again proves that birds are direct descendants of dinosaurs."

The Brontosaurus is a lie

The wrong head

In 1879 a paleontologist named Othniel C. Marsh uncovered a large sauropod skeleton, he dubbed it Brontosaurus which means “thunder lizard” referring to the beasts great size. This name stuck and the brontosaurus became almost as famous as its great size. But there was a problem with this skeleton it was not a real dinosaur! The skeleton that Marsh found was headless, so he simply looked for the nearest head he could find which was miles away in a different quarry. It turns out this head belonged to a different animal a Camarasaurus! This terrible mix-up lasted until 1975 when two scientists, Dr. Jack McIntosh and Dr. David Berman, proved to the scientific community that the brontosaurus was simply an Apatosaurus with a Camarasaurus head, and that day the brontosaurus died (not really it died like 65 million years ago) and the Apatosaurus took its place. But Brontosaurus was engraved into peoples heads and the term Brontosaurus is still alive and well, as people still pass on the bad information that they have been taught.
