Mixed graveyards filled with exceptionally well-preserved dinosaurs, mammals, early birds, fish, and reptiles in northern China are the result of lethal volcanic flows, according to new work by an international team of geologists and paleontologists.
Scientists at the American Museum of Natural History and Stony Brook University have demonstrated a new way to calculate the temperature of the ocean 80 million years ago: through the jaws of ammonites.
An international group of astrophysicists including Museum Curator Mordecai-Mark Mac Low has found evidence strongly supporting a solution to a long-standing puzzle about the birth of some of the most massive stars in the universe.
A series of papers recently published by scientists at the American Museum of Natural History suggests that polar bears in the warming Arctic are turning to alternate food sources. As Arctic sea ice melts earlier and freezes later each year, polar bears have a limited amount of time to hunt their historically preferred prey—ringed seal pups—and must spend more time on land.
