Tooth fossils of Asian elephants (Elephas sp. ) and the now-extinct stegodonts (Stegodon sp.) were found in the hills of Sitio Bitoguan, Barangay Jelicuon, Cabatuan, Iloilo in 1965 and 1967, respectively. The artifacts were dated to 750,000 years old (Middle Pleistocene).

The elephants and stegodonts looked similar except that stegodonts have longer (up to 10 feet long) and straighter tusks that grew close together. An elephant has four high-crowned, multi-plated molars, allowing it to graze on grasses and leaves in dense forests. The lower molars curve inwards (concave) while the upper molars on curve outwards. Stegodont has low-crowned, roofed teeth that is well adapted to browsing on twigs and leaves 1O on trees in both the savannas and wooden areas.

The Elephas sp. was survived by the endangered Asian elephant (Elephas maximus). The stegodont went extinct from 11.6 million years ago to the late Pleistocene. Their feeding habits (browsers) could have affected their survival when environmental conditions changed. Elephas sp. has molars with compressed diamond-shaped structures called lamellae that are adaptable to grinding grasses.

The same fossils were found in Pangasinan, Rizal, Cagayan Valley, and Davao. Animals walked on land bridges when the sea levels dropped an average of 120 meters lower than it is today about 790,000 years ago. Panay, Guimaras, Negros, Cebu, and Masbate were once connected as the Greater Negros-Panay Pleistocene Aggregate Island Complex, thus, the distribution and endemicity of animals among these islands are similar But the Greater Luzon, Visayas, and Mindanao PAIC were not connected by land bridges. How come elephants and stegodonts were found on these islands? These large mammals are believed to be very good swimmers.
