100 Million Year Old Flower Discovered in Amber

Tropidogyne pentaptera

Just look at this thing. You can see all of the veining and tiny hairs on the pedals. It looks like something out of Stranger Things.

Scientists think dinosaurs brushed these ancient flowers into pools of tree resin, creating fossils preserved in amber. A Triceratops bulling its way through a pine forest likely dislodged flowers that 100 million years later have been identified in their fossilized form as a new species of tree.

George Poinar Jr., professor emeritus in Oregon State University’s College of Science, said it’s the first time seven complete flowers of this age have been reported in a single study. The flowers range from 3.4 to 5 millimeters in diameter, necessitating study under a microscope.



“The amber preserved the floral parts so well that they look like they were just picked from the garden,” Poinar said. “Dinosaurs may have knocked the branches that dropped the flowers into resin deposits on the bark of an araucaria tree, which is thought to have produced the resin that fossilized into the amber. Araucaria trees are related to kauri pines found today in New Zealand and Australia, and kauri pines produce a special resin that resists weathering.”
