I want to know the answer to the following question:
In what year did Tufts researchers reportedly uncover what is believed to be the oldest known impression of a flying insect?
All the background I'm provided with is that "In 2008, researchers at Tufts University uncovered what they believe is the world's oldest known full-body impression of a primitive flying insect, a 300 million-year-old specimen from the Carboniferous period.". Is that enough to answer the question?
