A Dipole Field from the Ediacaran-Cambrian Transition Onward?
The Ediacaran features an instable magnetic field complicating paleogeographic reconstructions; a new paleointensity study on late Ediacaran rocks indicates a weak but stable dipolar field.

How Did Fragile Early Microbes Become Fossils?
During the Ediacaran period more than a half billion years ago, clay mineral coats likely shielded delicate remains, helping them become exquisitely preserved in rock, recent experiments suggest.
