What to know about Where was Baltica 616 million years ago? Paleomagnetic data offer revised answer

Researchers analyzed rock samples from Egersund, Norway, to determine the position of the ancient continent Baltica during the Ediacaran period. The study found complex, conflicting magnetic signals, leading the team to suggest Baltica was located near the equator and adjacent to Laurentia.

What happened

Paleomagnetic data offer revised answer Gaby Clark Scientific Editor Robert Egan Associate Editor About 600 million years ago, the continents wandered Earth, yet to settle into their current positions.

Why it matters

Their locations during the Ediacaran (as this time is called) have been tough for scientists to pin down.

Common ground

Earth's magnetic field appears to have behaved in erratic ways, and applying standard techniques to calculate the continents' positions based on records of the magnetic field yields implausible results.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.

Researchers analyzed rock samples from Egersund, Norway, to determine the position of the ancient continent Baltica during the Ediacaran period. The study found complex, conflicting magnetic signals, leading the team to suggest Baltica was located near the equator and adjacent to Laurentia.
