The fossilized walnuts were discovered on the northern Canadian island of Axel Heiberg, which was covered with rainforest 45 million years ago. By using CT technology, Manchester identified the three new species of walnuts.
The fossils gathered and identified from Axel Heiberg in this study help explain where modern walnuts evolved from.
"When you walk into the site, the first thing you notice are these big stumps, a meter or more in diameter, and they're still rooted in the soil that they grew in. It's completely out of place. The closest living trees are 3,000 kilometers away," Basinger said in a Florida Museum of Natural History news release.
