From the article: "The researchers also analyzed other fossils for the presence of soft tissue, and found it was present in about half of their samples going back to the Jurassic Period, which lasted from 145.5 million to 199.6 million years ago, Schweitzer said."

... And ...

"It turns out that soft tissue can be pickled in the equivalent of formaldehyde and that is good enough to preserve the material somewhat."

Pickled for "... from 145.5 million to 199.6 million years ago ..." ? Come on you jokers. When are you going to realize that your timeline is way off? Give it a break and use some sense.
