Where was Baltica 616 million years ago? Paleomagnetic data offer revised answer

Phys · · 409 words · By Saima May Sidik

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.
