Ancient Sea Cow Fueled Climate Solutions 21M Years Ago

Scientists have unveiled Salwasiren qatarensis, an ancient sea cow species discovered in Qatar that lived 21 million years ago. These mammals were crucial 'ecosystem engineers,' nurturing seagrass beds that store significant carbon, thus contributing to natural climate solutions. Their fossilized remains reveal a vital role in coastal ecosystems of the Persian Gulf, promoting biodiversity through nutrient cycling.

Beyond marine life, new species discoveries continue across diverse environments. A unique mouse opossum, Marmosa chachapoya, was identified high in the Peruvian Andes, emphasizing the region's biodiversity. Meanwhile, a new genus of spider, Siskiyu armilla, was discovered in Northern California, underscoring the state's rich arachnid diversity. Additionally, a striking bumpy snailfish was documented off the coast of Central California.
