After the show had been broadcast, one of the paleontologists, Matt Wedel, wrote an angry blog entry about how the production company, Dangerous Ltd., quote-mined him in an episode he appeared in, which ended up forwarding false information to the viewers about the "second brain theory" in sauropods (long-necked plant-eating dinosaurs). He originally claimed that this is an outdated theory, and that scientists are still unsure about the functions of the so-called "second brain" (actually a widened area on the spinal cord, which is common in many animals), however in the final cut, he seemingly said the theory still held water. The Discovery Channel (who aired the show but did not directly produce it) later went back to revise the segment. See more
