The study, published in the Proceedings of the National Academy of Sciences, focused on the fossils of cladoxylopsids. While trees today have a central vascular system called a xylem at their center, these ancient specimens had multiple xylems located in the outer 5 centimeters (2 inches) of the trunk.
