Yesterday, researchers discovered a 165-million-year-old New Euthemistid Damsel-Dragonfly fossil from the Middle Jurassic in Chifeng City, Inner Mongolia Autonomous Region. This discovery provides a new scientific basis for studying the natural history and evolution of dragonflies.

"This insect fossil is one of the best preserved Euthemistidae fossils to date. Its wings, body, and genitalia are all preserved, and most unusually, it can be seen from its genitalia that it was a female individual." Said Ren Dong, a professor at the School of Life Sciences at Capital Normal University.

Based on previous research on the this area, experts speculate that this kind of dragonfly lived next to warm and humid streams or lakes. This discovery supplements some characteristics of Euthemistidae, providing the international entomological community with a more comprehensive morphological basis, and further enriching the understanding of Euthemistidae.

According to Shang Jingan, director of the Ningcheng National Geopark Administration, staff discovered the exposed dragonfly fossil during a paleontological fossil protection inspection. Experts then conducted on-site verification and research, and protective measures were taken.

Professor Ren pointed out that this discovery is of great significance in revealing the evolutionary history and ecological adaptability of dragonflies. This fossil discovery not only helps people understand the evolution of Euthemistidae, but also provides new clues for studying the ecological environment and biodiversity of the Middle Jurassic.
