Research Posits Fossil Tree Growth Method
The evolution of trees and forests in the Middle to Late Devonian Period, 393–359 million years ago, profoundly transformed the terrestrial environment and atmosphere. The oldest fossil trees belong to the class Cladoxylopsida. In general, their water-conducting system was a ring of hundreds of ... |

A step toward a complete Triassic time scale: the proposal from China
The Triassic Period (252-201 million years ago) is bounded by two mass extinctions, but the time scale of the Late Triassic still remains controversial. A new study published in Earth and Planetary Science Letters, a top journal of geoscience sheds light on this critical problem.
A research g... |
