World’s Largest Worm Lizard Fossil Discovered

Two perfectly articulated skeletons of the sheep-size dinosaur Psittacosaurus, found in China’s Yixian Formation. New research suggests they died in burrow collapses, not via volcanism, as previously thought. (Jun Liu, Institute of Paleontology and Paleoanthropology, Chinese Academy of Sciences)

Did the world’s best-preserved dinosaurs really die in ‘Pompeii-type’ events?

Brazilian fossils reveal jaw-dropping discovery in mammal evolution

Results of the multimodal analysis conducted on microfossils mounted on ITO glass. Optical observation, electron microscopy, and secondary ion mass spectrometry were performed on the same sample. The analysis successfully detected phosphorus and molybdenum aligned with the microfossil's membrane structure for the first time. ©Tohoku University
