The "David H. Koch Hall of Fossils—Deep Time," a 31,000-square-foot dinosaur and fossil hall at the Smithsonian’s National Museum of Natural History, takes visitors on a journey through deep time to explore ancient ecosystems, experience the evolution of plant and animal life and get up close with some 700 specimens.
The new paper is part of an ongoing research effort that began in 2018, when Smithsonian researchers were helping develop the museum’s “David H. Koch Hall of Fossils— Deep Time.” The team wanted to provide museum visitors with a curve that charted Earth’s global mean surface temperature across the Phanerozoic, which began around 540 million years ago and continues into the present day.
A new study co-led by the Smithsonian and the University of Arizona offers the most detailed glimpse yet of how Earth’s surface temperature has changed over the past 485 million years. In a paper published today, Sept. 19, in the journal Science, a team of researchers produce a curve of global mean surface temperature across deep time—the Earth’s ancient past stretching over many millions of years.
