New fossil tree species discovered in Ethiopia’s Mush Valley

Scientists have discovered a new species of ancient tree fossil called Astropanax eogetem. This finding provides insights into life in a prehistoric forest in Ethiopia, dating back around 22 million years to the early Miocene period. The fossils were located in the Mush Valley, about 160 miles northeast of Addis Ababa. Dr. Aaron Pan, along with his team from the Botanical Research Institute of Texas and Texas Tech University, has been excavating this site. They found a variety of well-preserved fossils, including tree species, frogs, insects, and mammal bones. Astropanax eogetem helps illustrate the diverse ecosystem that existed at that time. The research indicates that this tropical forest was rich with life, including animals like clawed frogs, and possibly even primates and giant elephant-like creatures. The tree belongs to the Araliaceae family, which includes plants like modern ginseng. Researchers identified the new species by carefully studying fossil leaves and pollen, comparing them with modern relatives. This meticulous work confirmed Astropanax eogetem as an extinct species. The name "Eogetem" combines Greek and Amharic words, honoring its historical and cultural significance. The research was made possible with the help of local communities and Ethiopian museum staff, reflecting collaboration in this scientific effort.
