The process shown in the 40-million-year-old amber is called precocious germination and typically only found among fruits, making this pine cone the earliest evidence of the occurrence in a cone.

The first fossil evidence of a pine cone sprouting seeds has been preserved in 40 million-year-old amber. Seed germination typically occurs in the ground after a seed has fallen, but several ...

Precocious germination in pine cones is so rare that only one naturally occurring example of this condition, from 1965, has been described in scientific literature, Poinar said in the statement.

The first fossil evidence of a rare botanical condition known as precocious germination in which seeds sprout before leaving the fruit ...

The hypothesis tested was that the temperature required to release seeds from serotinous cones of lodgepole pine would have an adverse effect on germination. Seeds were mechanically removed from cones ...
