This was recently posted on Kent Hovind's website (currently being run by his son) and has been doing the rounds in creationist circles.
The story: In 1999, a teenager named Tyler Lyson unearthed a rare find on his family's farm in North Dakota. It is the fossil of a hadrosaur which has been mummified, though to be more specific, the bones have been mineralised and the whole body is in an unusually excellent state of preservation, which includes skin and soft tissues. This find has recently been in the news because of the publication of a book by National Geographic, titled Grave Secrets of Dinosaurs: Soft Tissues and Hard Science. You can read more about it
here, though the news story is easy to find in many places on the web.
Hovind claims that due to the rare preservation of skin and mummification, the creature had to be buried "very rapidly, in flash flood conditions." And this could have happened 4,400 years ago during the Biblical global flood. The fossil was encased in siderite, which bears out the idea that the fossilisation occurred quickly. I also cannot find any information about possible radioisotope dating of rock surrounding the fossil.
I'm going to play devil's advocate here. This hadrosaur fossil is excellent evidence of the Biblical global flood that occurred 4,400 years ago. The fossil is not millions of years old. Refutations welcome.
