Ancient Fossils Reveal Magnetic Field Navigation
Scientists found tiny fossils from 97 million years ago that show animals used Earth's magnetic field to navigate, like a built-in GPS.
They used a special technique called magnetic tomography to see inside these fossils.
This technique helps them understand how these ancient creatures knew where they were going.
The fossils were studied at a special place called the Diamond X-ray Facility in Oxford.
The scientists think these organisms could tell direction and location very accurately.
This discovery helps us learn more about how animals have been using the Earth's magnetic field for a very long time.
Scientists discovered 97-million-year-old fossils showing evidence of magnetoreception.
Magnetoreception is a biological GPS that helps animals navigate using Earth's magnetic field.
Researchers used magnetic tomography to study the internal structure of the fossils.
The fossils were studied at the Diamond X-ray Facility in Oxford.
The findings suggest ancient organisms could accurately determine direction and location.
