Washington, Oct 23 : A team of scientists has unearthed crystalline magnetic fossils of a previously unknown species of microorganism that lived at the boundary of the Paleocene and Eocene epochs, some 55 million years ago.
The team comprised of researchers from McGill University, along with colleagues from the California Institute of Technology, the Curie Institute in Paris, Princeton University and other institutions.
Though they are only some four microns long, these newly discovered, spear-shaped magnetite crystals (magnetofossils) – unearthed at a dig in New Jersey – are up to eight times larger than previously known magnetofossils.
