The hedgehog and primitive cricket are relatively early mammals that existed from the Eocene—about 50 million years ago. Their fossils were discovered in Driftwood Canyon. The newly discovered creature is called Heptodon. It is very different, not only because it is an undiscovered species, but because the animal's skull is very small - only about half a centimeter long.
This forced scientists to use 3D scanning techniques to examine specimens and prove that they had discovered a new species: Silvacola acares ("Little Forest Residents"). The scientists hope to find more Eocene mammals in the driftwood gorge, thus elucidating how the ancestors of modern animals lived in the era of the highest temperature in the world since the extinction of dinosaurs. At that time, there were no polar ice caps and crocodiles could be found in the Arctic.
JHP series gold-loaded carbon medium temperature non-cyanide desorption and same temperature electrolysis equipment was developed by Changchun Gold Research Institute Co., Ltd. in 1998 and entered the market. It has been used in more than 800 enterprises at home and abroad. This series of equipment is oriented to the gold-loaded carbon in the gold cyanide carbon slurry process for gold desorption and electrolysis, and the gold adsorbed on the gold-loaded carbon is produced in the form of high-grade gold mud. After decades of practical application and continuous optimization and improvement in enterprises, this series of equipment has developed to the fifth generation.
