A team of paleontologists from China University of Geosciences (Beijing) studying penguin fossils from Seymour Island off the Antarctic Peninsula have demonstrated how ancient bird bones can act as chemical archives of past climate change. The researchers used nondestructive X-ray mapping to examine the elemental composition of penguin remains spanning millions of years. They uncovered key insights into how Antarctica shifted from a warm, humid environment to a cooler world. The work is published in the journal Fossil Record.
