A Tar Pits researcher reconstructed forests of 56 million years ago—with chilling parallels for our warming planet: climate change led to a widespread browning of Earth's landscapes—against a backdrop of elevated atmospheric CO₂, global warming, and reduced rainfall triggered by volcanically driven carbon release—and trees are at the root of these drastic changes.

The first new extinct toad species and the first description of the Mexican burrowing toad at the Tar Pits help us understand the impacts of climate change on species distributions, past, present, and future.

Published in the journal Science, a new study by NHM researchers shows that Mexico acted as a biodiversity "holding pen" for 10 million years ahead of the Great American Biotic Interchange that opened the floodgates between North and South America 2.8 million years ago.
