Paleocene Age 60 million years ago

Bring a piece of prehistoric Earth into your collection with this remarkable Zizyphoides Flabellum fossil leaf, dating to the early Paleocene Epoch, roughly 66–56 million years ago. This leaf originates from a transformative period following the Cretaceous–Paleogene mass extinction, when non-avian dinosaurs, giant marine reptiles, and many other species disappeared, leaving forests to recover and flourish. During the Paleocene, the planet was warm and ice-free, with dense subtropical, tropical, and deciduous forests covering even polar regions. These conditions allowed early flowering plants (angiosperms), palms, and cacti to thrive, shaping the first recognizable modern forests. The fossil preserves delicate leaf details, making it a visually striking specimen ideal for display or study. With forests denser than in the Cretaceous, fossils like this illustrate the resilience, diversity, and early evolution of modern plant life. Perfect for fossil collectors, paleobotany enthusiasts, educators, and museums, this Zizyphoides Flabellum leaf is more than a fossil—it is a tangible connection to Earth’s ancient ecosystems, a rare and beautiful piece of prehistoric history that enhances any collection or exhibit.
