Exceptional Fossilized Hippopotamus Tusk – Hippopotamus sivajavanicus, Late Lower Pleistocene: Solo River, Java, Indonesia

This listing is for a genuine fossilized Hippopotamus sivajavanicus tusk, dating back to the Late Lower Pleistocene(~1.2 to 0.8 million years ago). This incredible specimen originates from the Solo River deposits in Java, Indonesia, an area renowned for its rich collection of Ice Age megafauna fossils.

Species Information – Hippopotamus sivajavanicus

Hippopotamus sivajavanicus was an extinct species of hippopotamus that roamed the riverbanks and floodplains of Java during the Pleistocene Epoch. It was closely related to modern hippos (Hippopotamus amphibius) but exhibited distinct anatomical differences, likely adapting to the tropical climate and changing environments of Southeast Asia.

Like its modern relatives, H. sivajavanicus was a semi-aquatic species, spending much of its time in rivers and lakes to regulate body temperature and avoid predators. These prehistoric hippos likely coexisted with other Ice Age megafauna, such as Stegodon elephants, giant tapirs, and early hominins, including Homo erectus, whose fossils have also been discovered in the Solo River region.

Key Features of Hippopotamus sivajavanicus:

🦛 Powerful Tusk-Like Canines – Used for territorial defense, dominance, and combat

🦛 Semi-Aquatic Adaptation – Thrived in the riverine environments of prehistoric Java

🦛 Coexisted with Early Humans – Fossils found alongside Homo erectus remains

Fossils of Hippopotamus sivajavanicus are rare and highly sought after, providing insight into the evolution of hippos in Southeast Asia and their eventual extinction.

Geological Context – Solo River Deposits, Java, Indonesia

The Solo River region in Java is one of the most important fossil sites in Southeast Asia. It has yielded a wealth of prehistoric fossils, including hominins (Java Man, Homo erectus), Stegodon elephants, and various Pleistocene mammals. The region’s fossil-bearing layers consist of alluvial deposits, formed by ancient river systems that preserved the remains of animals that once thrived in Java’s tropical environment.

This Hippopotamus sivajavanicus tusk fossil is an exceptional specimen from this famous fossil site, showcasing impressive surface preservation and characteristic enamel detail.
