Bubalus palaeokerabau

A giant buffalo of Java with spectacular horns. Bubalus palaeokerabau roamed Late‑Pleistocene Sundaland. With horns that could span roughly 2.5 m across, this buffalo dwarfed modern domestic water buffalo and inhabited the wetlands and savanna of ancient Java.

Description

Fossils from the Cisaat and Pucangan formations show that B. palaeokerabau was a large wild buffalo endemic to Java during the Late Pleistocene. It likely resembled the modern wild water‑buffalo, but its horns were far longer – about 2.5 m – and the animal was heavier than domestic buffalo. Analogy with the wild water‑buffalo suggests body masses around 700–1 200 kg, heights of ~1.8–2 m and lengths of 2.4–3 m. These bovids probably grazed on grasses and aquatic plants in flooded plains and forest‑savanna mosaics, forming herds near water sources.

Palaeobiogeographic studies place the species within a group of bubaline water‑buffalo that dispersed across Sundaland when lowered sea levels connected mainland Asia to Java. Its long horns and robust build may have evolved under predator pressure and sexual selection.

Hunt History

Human ancestors on Java encountered large bovids. Cut‑marked bovid bones from the Pucangan Formation suggest Homo erectus butchered large bovids between 1.6 and 1.5 Ma, and a bone bed at Ngandong contains remains of deer and large bovid ancestors of water‑buffalo and banteng. Although B. palaeokerabau appears later in the Pleistocene, these sites show that hominins were already exploiting large buffalo; later Homo sapiens likely hunted and eventually extirpated the long‑horned species.
1. Cisaat and Pucangan formations (Java) – fossils of B. palaeokerabau indicate a giant water‑buffalo endemic to Java during the Late Pleistocene.
2. Sangiran (Java) – cut‑marks on large bovid bones dating to 1.6–1.5 Ma show that Homo erectus butchered buffalo‑sized animals.
3. Ngandong bone bed (Java) – a rich deposit of deer and large bovid remains, including ancestors of water‑buffalo, suggests that archaic humans scavenged or hunted these animals.
