Rare Fossilized Feathers Reveal Secrets of Ancient Paleontology Hotspot

[+Grim Reaper 6]

Jehol Biota in China is renowned for its exceptional fossils that retain soft tissue such as skin, feathers, organs, and fur. These fossils offer a unique perspective on the evolution of traits like flight, but require careful interpretation to understand the appearance and behavior of the soft tissue in life and the effects of decomposition. A study in Frontiers in Earth Science analyzed five fossils of the early Cretaceous bird Sapeornis chaoyangensis to examine the impact of the burial environment on the preservation of soft tissue.

“Jehol Biota provides the most informative source for understanding Mesozoic ecology,” said corresponding author Dr. Yan Zhao, based at the Institute of Geology and Paleontology, Linyi University. “Better understanding of the diverse taphonomy of Jehol terrestrial vertebrates can help us finally understand more about the past and future of biological evolution
