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 ...

Many empty shells of bivalves produced by a local subpopulation will disarticulate into left and right valves between death and final burial in open and shallow seas. In areas above the normal wave ...

Barium:calcium and molybdenum:calcium ratios were investigated in shells of the tropical scallop Comptopallium radula. Three juvenile specimens were harvested alive in the southwest lagoon of New ...

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.
