Scientists say they've uncovered a pile of 1,800 Jurassic turtle skeletons in China that had been swept into a mass grave millions of years ago. The fossilized mesa chelonia turtles were found in China's northwest province of Xinjiang in what paleontologists call a "bone bed" with some of the shells stacked up on top of each other in the rock. Some 160 million years ago, these turtles (identified as a species in the genus Annemys) likely had gathered in one of the remaining waterholes during a very dry period, awaiting rain, which apparently came too late, the researchers say. When all the water left in the hole dried up, the turtles died. When the rain did finally arrive, it hit with catastrophic force.

| -0.093324 | "We know from living organisms that individuals of some species look very similar, whereas individuals of other species show a lot of variation," Joyce wrote in an email to LiveScience. "As a paleontologist, it is therefore always difficult to assess if your fossil looks different from others because it is a new species, or because it is part of an already known, but variable species. With data from the new site we will finally be able to more rigorously assess patterns of diversity of turtles in the Jurassic of Asia." |

Key:
- Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
