The stomach contents of the 47-million-year-old fossil flyer—a long-extinct species of perching bird—include hundreds of grains of pollen. The ancient pollen grains are large and apparently clumped together readily, a clue that the plant that bore the flowers was pollinated by creatures and not by the wind." Link to Original Source
