Paleokarst in Phong Nha - Ke Bang - Hin Nam No and its Geomorphological and Geological Values
A groundbreaking discovery of paleokarst landforms in Phong Nha-Ke Bang National Park (Vietnam) and Hin Nam No National Park (Laos) reveals karstification dating back to the Triassic, predating previous estimates by millions of years. This study, confirmed through field surveys and thin-section analyses, identifies buried karst surfaces and filled fissures/caves developed on Devonian to Carboniferous-Permian limestones, providing critical evidence for karst evolution from the Triassic to Middle Jurassic. The findings suggest a new direction for karst research in Vietnam and propose that these paleokarst sites could represent significant Outstanding Universal Value (OUV) for the combined PNKB HNN region.
The first record of living “Fossil” species (Laonestes aenigmanus) in Phong Nha - Ke Bang, Quang Binh province, Vietnam
Researchers confirm the presence of Laonestes aenigmamus, a living 'fossil' species thought extinct since the Miocene, in Phong Nha-Ke Bang National Park, Vietnam. This discovery extends its known range from Hin Nam No National Biodiversity Conservation Area (Lao PDR) to central Vietnam, marking it as the sole surviving member of an ancient rodent family. The study identified four specimens through morphological and skull analysis, proposing the Vietnamese name 'Truong son Rat' (Annamite Rat). Threats include hunting and forest destruction, with urgent conservation action recommended due to its limited distribution and ecological significance.
