  • The 4.5-billion-year-old Martian meteorite tagged as ALH84001, must have shuttled life forms from the red planet. 
  • Magnetotactic Bacteria
    • discovered by Richard P. Blakemore in the early 1970s
  • Magnetosomes
    • highly organized structure
    • They found out that the magnetotactic behavior of the bacteria is due to the presence of nano-sized membrane-bound magnetic crystals of magnetite (Fe3O4) or greigite (F3S4) aligned in chains perpendicular to the cell axis. 
  • 1996 David Mckay
    • Reported the striking morphological and chemical similarities of magnetofossils on Eart and ALH84001
