99 million-year-old flowers found preserved

Flowers discovered preserved in globs of amber bloomed at the feet of dinosaurs, suggesting that some flowering plants in South Africa today have remained unchanged for 99 million years, a new study reveals. The two flowers once bloomed in what is now Myanmar and may shed light on how flowering plants evolved — a major episode in the history of life that was once described by Charles Darwin as an “abominable mystery.”

Flowers are ephemeral: They bloom, transform into a fruit and then disappear. As such, ancient flowers aren’t well represented in the fossil record, making these ancient blooms — and the history they carry with them — particularly precious.

“Leaves are generally produced in larger numbers than flowers and are much more robust — they have a higher preservation potential. A leaf is discarded ‘as is’ at the end of its useful life, while a flower transforms into a fruit, which then gets eaten or disintegrates as part of the seed dispersal process,” said study author Robert Spicer, a professor emeritus in the School of Environment, Earth and Ecosystem Sciences at The Open University in the United Kingdom.

“These particular flowers are almost identical to their modern relatives. There really are no major differences,” added Spicer, who is also a visiting professor at Xishuangbanna Tropical Botanical Garden in China.
