Researchers examined ancient plagioclase crystals to learn about Earth's history.
A new study has discovered a startling record in which the Earth’s magnetic field diminished for up to 26 million years.
A new study led by the University of Rochester researchers discovered a startling record in which the Earth’s magnetic field diminished for up to 26 million years, from 591 to 565 million years ago.New quantum magnetometer to map Earth’s magnetic field from space As per a new study, this period marked the emergence of the Ediacaran fauna, which includes some of the oldest complex multicellular animals known to science.It has been long thought that the weak magnetic field would have been detrimental for earlier life forms due to the exposure to constant radiation and solar winds.
However, some fossil records have unraveled that these organisms diversified rapidly — both in complexity and type — between 575 and 565 million years ago.
