UNDIP, Semarang (6/5) – Professor of the Faculty of Fisheries and Marine Sciences (FPIK), Universitas Diponegoro (UNDIP), Prof. Dr. Agus Hartoko, revealed scientific facts about the existence of ancient megafauna in Indonesian waters, particularly the ancient shark Megalodon (Otodus megalodon). This giant species is known to have once inhabited the warm waters south of Sukabumi Regency, West Java, during the Miocene to Pliocene periods, around 16 million to 3.5 million years ago. Based on fossil tooth evidence, Megalodon had a massive body size, reaching more than 18 meters in length and weighing at least 65 tons.
Geologically, the presence of this apex predator in the Nusantara region was influenced by Indonesia’s location at the meeting point of three major continental plates: Asia, Australia, and the Pacific. This convergence of continental shelves created highly fertile marine ecosystems, making the region a meeting point for various flora and fauna from around the world. “Why could it exist in Indonesia? Because Indonesia was formed by the convergence of three continental plates: Asia, Australia, and the Pacific,” Prof. Agus explained.
Although Megalodon became extinct in the mid-Pliocene due to changes in global ocean conditions, evidence of its existence in Indonesia holds strategic value for national academic studies. The identification of various ancient shark species through fossilized teeth serves as authentic evidence that Indonesia’s natural dynamics have shaped a unique and historically rich natural heritage. In-depth research on these ancient animals is an important instrument for drawing international attention to Indonesia’s maritime potential and history.
In closing, the exploration of ancient fauna and natural phenomena in Indonesian waters is expected to strengthen the spirit of national sovereignty over the country’s marine wealth. Knowledge of this natural heritage is not merely a historical study, but also a foundation for strengthening Indonesia’s sovereignty over its marine resources. Prof. Agus Hartoko emphasized the importance of continuous research on Indonesia’s potential for marine flora and fauna to preserve the nation’s dignity and natural wealth for the future.
