Bivalves, such as clams, oysters and mussels, record seasonal environmental changes in their shells, making them living chronicles of climate history. A new study of bivalve shells has detected two ...

A new paleontology study by UChicago researchers discovered that rock-boring clams, known as bivalves, vary in shape despite performing the same function. This paper is one of the first major studies ...

A clam shell may be a familiar find on the beach, but its intricate curves and markings tell a rich tale. For centuries, biologists have collected, drawn, measured and compared the shells of bivalve ...

The fossil record may not be perfect, but it passed a critical test with flying colors, according to a study by University of Chicago paleontologist Susan M. Kidwell that will be published in the Feb.
