Dinosaur 'soft tissue' (including blood vessels) discovered

Researchers found soft tissue in the fossilized femur of a duck-billed dinosaur (hadrosaur). (National Geographic) The 80-million-year-old specimen includes "blood vessels and other connective tissue as well as perhaps blood cell proteins."

Amazing. Just amazing. What's more, this is
the second time we've found preserved dinosaur tissue. (The first find was in 2005)

In the latest finding, there's a strong possibility that the dinosaur's hemoglobin is in tact. So what? "Confirmed dinosaur-hemoglobin discovery would open the door to the recovery of many dinosaur proteins, including DNA proteins… "raising the specter of Jurassic Park-style 'resurrections.'"

As you can imagine, these findings are deeply controversial. Last year, a group of scientists claimed
the 2005 dinosaur soft-tissue find was just bacterial slime.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
