The paleontologist and her colleagues removed mineral fragments from the interior of the femur by soaking it in a weak acid. The fossil dissolved, exposing a flexible, stretchy material and transparent vessels. The vessels resemble blood vessels, cells, and the protein matrix that bodies generate when bones are being formed.
This shifting perspective clicked with Schweitzer's intuitions that dinosaur remains were more than chunks of stone. Once, when she was working with a T. rex skeleton harvested from Hell Creek, she noticed that the fossil exuded a distinctly organic odor. "It smelled just like one of the cadavers we had in the lab who had been treated with chemotherapy before he died," she says. Given the conventional wisdom that such fossils were made up
entirely of minerals, Schweitzer was anxious when mentioning this to Horner. "But he said, 'Oh, yeah, all Hell Creek bones smell,'" she says. To most old-line paleontologists, the smell of death didn't even register. To Schweitzer, it meant that traces of life might still cling to those bones. She had already seen signs of exceptional preservation in the early 1990s, while she was studying the technical aspects of adhering fossil slices to microscope slides. One day a collaborator brought a T. rex slide to a conference and showed it to a pathologist, who examined it under a microscope. "The guy looked at it and said, 'Do you realize you've got red blood cells in that bone?' " Schweitzer remembers. "My colleague brought it back and showed me, and I just got goose bumps, because everyone knows these things don't last for 65 million years."

We're better of concentrating on stop killing off what we have now rather then try & resurrect what used to be. Btw that's a pretty flower, wouldn't mind having one in my garden.

Want your own dinosaur?
You will need this:
1- A team of researchers. Good ones.
2- A well preserved dinosaur fossil. Not sure how will you get it.
3- A female Chicken.
With some science and luck, you can do it. Hell, they are doing it right now. I can’t find the news link but, I found this which really give the same result.
Sure, maybe we can’t do it but we might as well try :p

I remember this discovery and after that they found large bones in drawers in museums all over had intact tissue. The article I read about it said this gives them the ability to clone animals.
Two years ago, Schweitzer gazed through a microscope in her laboratory at North Carolina State University and saw lifelike tissue that had no business inhabiting a fossilized dinosaur skeleton: fibrous matrix, stretchy like a wet scab on human skin; what appeared to be supple bone cells, their three-dimensional shapes intact; and translucent blood vessels that looked as if they could have come straight from an ostrich at the zoo.
Nature is a wondrous beauty as the ice age flower blooms after 32000 years of being non-existent.
Silene stenophylla is a species of flowering plant in the family Caryophyllaceae. Commonly called narrow-leafed campion, it is a species in the genus Silene. It grows in the Arctic tundra of far eastern Siberia and the mountains of Northern Japan. Frozen samples, estimated via radiocarbon dating to be around 32,000 years old, were discovered in the same area as current living specimens; and in 2012, a team claimed to have successfully regenerated a plant from the samples.
