A study led by researchers at the American Museum of Natural History presents the oldest known example in the fossil record of an evolutionary arms race. These 517-million-year-old predator-prey ...

Tiny plankton shells used to reconstruct past polar ocean temperatures may contain two different chemical stories, a new study by iC3 researchers has found. The work shows that Neogloboquadrina ...

A construction project at San Pedro High School in Los Angeles revealed nearly 9-million-year-old sea creature fossils buried under the school. Scientists believe the area was once fully underwater, ...

Skeleton season may be just around the corner, but the skeleton age dawned with the early Cambrian Period, about 538 million to 506 million years ago. In this time span, most major animal groups ...

This hunt started with fossil shells but turned into something unexpected. Inside several fossils were calcite crystals ...

A new study finds that shells of the polar plankton Neogloboquadrina pachyderma can record two distinct chemical signals, potentially distorting reconstructions of past ocean temperatures. Researchers ...
