Giant magnetofossils and hyperthermal events

Chang, Liao; Roberts, Andrew; Williams, Wyn; Fitz Gerald, John; Larrasoana, Juan; Jovane, Luigi; Muxworthy, Adrian R

Description

Magnetotactic bacteria biomineralize magnetic minerals with precisely controlled size, morphology, and stoichiometry. These cosmopolitan bacteria are widely observed in aquatic environments. If preserved after burial, the inorganic remains of magnetotactic bacteria act as magnetofossils that record ancient geomagnetic field variations. They also have potential to provide paleoenvironmental information. In contrast to conventional magnetofossils, giant magnetofossils (most likely produced by...[Show more]
