In order to ascertain the ages of samples which were formed in equilibrium with different reservoirs to these materials, it is necessary to provide an age correction.

Some cells, like those found in skin, hair, and the lining of the gut, are produced and discarded on a regular basis, like doodles on scrap paper. Kirsty Spalding was one of the scientists who doubted that assessment.The turtles either died naturally or were harvested for their decorative shells as part of the global tortoiseshell trade.The researchers worked with federal agencies, law enforcement, and museum archives to obtain the specimens.“The most basic questions of sea turtle life history are also the most elusive,” says Kyle Van Houtan, adjunct associate professor at Duke University’s Nicholas School of the Environment and a fisheries research ecologist at the National Oceanic and Atmospheric Association’s Pacific Islands Fisheries Science Center.As reported in the journal , researchers analyzed hard tissue from the shells of 36 deceased hawksbill sea turtles collected since the 1950s.
