Amber captures rare plant behavior in an ancient, extinct pine cone
CNN
The first fossil evidence of a pine cone sprouting seeds, a rare botanical feat, has been preserved in 40 million-year-old amber.
Seed germination typically occurs in the ground after a seed has fallen, but several embryonic stems were captured emerging from the ancient pine cone in a rare botanical feat known as precocious germination, or viviparity, in which seeds sprout before leaving the fruit.
