(Newser) – A trove of 195 million-year-old fossilized dinosaur embryos—among the oldest ever found—has given scientists an "unprecedented" look at how those ancient creatures grew. The Wall Street Journal reports on the Chinese discovery, which first came to light three years ago and is believed to be the remains of what would have grown into the 30-feet-long Lufengosaurus, a common plant-eater in the early Jurassic period. "These things were growing faster [in the egg] than anything we've ever seen—faster than any living mammal or bird today or any known dinosaur," says the paleontologist who led the expedition.

Dinosaur eggs are usually found mostly intact, so people are reluctant to cut them open and examine the embryos. But these bones, found in Dawa, Yunnan Province, China, weren't encased in eggs, or even near the remains of a nest or mother; scientists have thus far unearthed 200 tiny bones among crushed eggshells, and note that they comprise embryos in different stages of development. Researchers think the eggs were probably swamped and crushed by a flood. Another neat revelation from the find: Dinosaurs probably kicked and twitched in their eggs, reports LiveScience.

I can appreciate the time and patience that the archeologist invested to make this find. Since this fossil does not stand out from a distance, it was most likely painstakingly searched for. My point is that professionals know what they are doing in their specific field of endeavor. Even though I am not an archeologist, I still find it educational to read about such a find.

The full article is much better. It explains how they could tell the animals grew fast and why this find is different.

I thought it said "breast secrets" and was going to give away an industry secret to explain people like Jenny McArthy. Then I realized her plastic doc can explain that quite well. As for the Bible references there are plenty of Christian scientists in the school of thought that the Bible has always referenced time in relative terms and the idea that billions of years of Earth development does fit in because if you truly believe in God's wonder, you would know that time has no meaning. One second or one trillion years, it just doesn't matter. If you don't believe that, you have trouble with the faith.
