Ancient kauri trees capture last collapse of Earth’s magnetic field

Several years ago, workers breaking ground for a power plant in New Zealand unearthed a record of a lost time: a 60-ton trunk from a kauri tree, the largest tree species in New Zealand. The tree, which grew 42,000 years ago, was preserved in a bog and its rings spanned 1700 years, capturing a tumultuous time when the world was turned upside down—at least magnetically speaking

Initial studies suggested that the fossils belonged to Baryonyx walkeri, but the reanalysis said otherwise. The team has renamed the new species of spinosaurus Iberospinus natarioi. The team considered it one of the most complete specimens of spinosaurus they found, says Professor Octavio Mateus of the NOVA School of Science and Technology.
