20-million-year-old fossil seeds shed light on origins of plant biodiversity in Panama.
Declining reefs
What were Caribbean coral reefs like before humans?
September 29, 2017
Fossil reefs from around the Caribbean show how biologically rich these ecosystems once were — and provide goalposts for conservationists hoping to restore them.
Flowers from Darkness
“Tropical forests are the result of an accident of history.” - Carlos Jaramillo.
April 23, 2018
About 66 million years ago, a radical change on the Earth filled tropical forests with flowers. A new catalog of fossil pollen grains may hold an explanation.
Redefining Pristine
Modern marine oxygen-deficiency research inspires search for fossil record
May 11, 2018
Smithsonian scientists who documented massive mortality of corals and reef organisms meticulously studied one of the apparent causes: oxygen deficiency. A Smithsonian paleobiologist asks if the recent fossil record shows signs of similar hypoxia events.
