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.
Not Resilient
Old Species Learn New Tricks…Very Slowly
August 23, 2018
Perhaps old species, like some older people, gradually lose their ability to deal with changes in their environment. Aaron O’Dea and colleagues show that when the Caribbean was cut off from the Pacific by the rise of the Panama land bridge, evolutionarily old species took longer to expand into new habitats than evolutionarily younger species did.
