Archaeopteryx: The Embargoed Tattoo

A fair number of scientists like to get a tattoo to celebrate their research. Ryan Carney, a biologist at Brown University has taken the practice one step further. He's gotten a tattoo that shows the key finding of a paper he and his colleagues have just published today. They studied a fossil feather from Archaeopteryx, the iconic bird (or almost-bird). They conclude it looked just like this tattoo. Carney collaborated on the research with a team of scientists who have developed a method to reconstruct colors from fossils. One source of colors in animals is a cellular structure called a melanosome. Depending on the size, shape, and spacing of melanosomes, they can produce a range of hues. It turns out that melanosomes are incredibly rugged, sometimes enduring for millions of years. As I wrote in the New York Times in 2009, the scientists first found melanosomes in the ink sac ...
