(PhysOrg.com) -- A beautifully preserved fossil identified as being of an early relative of the Asteraceae, or aster, family nearly 50 million years old suggests the plant family, which has now colonized much of the planet, originated in South America after Gondwana separated, forming South America, Australia, Africa, Antarctica and India.
The most striking feature of the fossil, which resembles a painting of sunflowers by 19th century Dutch painter Van Gogh, is a dense flower head (capitulum) like that forming the central part of a sunflower and providing a strong attraction for pollinators.
