If these scientists shopped at a typical grocery store, they couldn't do their experiments. Apparently, they looked for chickens with their necks where they should be, and even with their heads still attached, and took pictures of them after pushing their necks around to various stages. Sound a bit macabre? To be fair, they were taking x-rays, not normal pictures, and they were then measuring the angles of the vertebrae connections at the various positions. Why, you ask? Because they think chickens are living (well, dead for the experiments) dinosaurs. They were hoping for insight into why so many fossilized dinosaurs are buried in rock appearing to be in what's been called the "throes of death" — called the opisthotonic posture — with the long neck extended unnaturally toward the animal’s back.
But this isn't the first time scientists have dabbled in dead dinosaurs, er, chickens. Back in 2011, Dr. Elizabeth Mitchell talked about a similar study where dead chickens were dunked in freshwater and observed to have the trademark neck recoil, apparently in response to the immersion. This has been observed in other studies as well. Of course this makes sense with a biblical Flood burial. But the action of the violent floodwaters, we would argue, is probably more the culprit.
