The oldest flower fossil in the world is found near the tourist city of Bariloche in Argentina's Patagonia province.

This finding will help scientists know the origin of chrysanthemum and sunflower may come from southern Argentina.

The above flower fossils belong to the daisy family, which includes about 25,000 different flower species such as daisies and sunflower.

Experts say the fossil is very unusual because of its flower form, while most fossils of plants found so far are in the form of seeds.

They hope this discovery will help people have a clearer understanding of the evolution of plants and their popularity on Earth.

Argentinian biologist Viviana Barreda, of the Buenos Aires Museum of Natural Science, said that probably from South America, the first species of the daisy family had " migrated " to other continents in the world.
