Yunnan Province, China holds some very special eggs, containing the tiny bones of unborn sauropod dinosaurs. Within the Lufeng Formation, a relatively thin bed of red sediment contains these fossil eggs, mixed and buried amidst other fossils. While perhaps providing new clues to the ways sauropod dinosaurs developed from embryos, they also bear distinct marks of very recent flooding.

Decades ago, when researchers began publishing their discoveries of transparent, floppy tissue with recognizable intact cells inside dinosaur bones, plenty of shocked evolutionists disputed their results. After all, nobody knew—and still nobody knows—a process whereby flesh and bones could persist over the eons that evolutionists insist dinosaur fossils have endured.

Original dinosaur tissues in fossil bones are probably the most controversial finds in all of paleontology. Secular scientists have difficulty interpreting them. They debate whether the tissues are real, based on laboratory-measured tissue decay rates, or whether the tissue decay rates are real, based on plainly observed tissues.

DNA is a biochemical that contains genetic information. And like all other cellular ingredients, it decays if cellular systems don't maintain it. Now, scientists are more confident about how fast it falls apart after a cell dies.
