Tiny plankton shells used to reconstruct past polar ocean temperatures may contain two different chemical stories, a new ...
Snail shells are often colorful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on ...
In the 1990s, paleontologists exploring dinosaur‑rich badlands in the Zuni Basin of western New Mexico uncovered a turtle ...
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 ...
