The oceans of Earth were once home to a creature so immense and powerful that its mere existence challenges human imagination. Carcharocles megalodon, commonly known as megalodon, reigned supreme as the most formidable predator of prehistoric seas. This colossal shark, whose name means “big tooth,” lived approximately 23 to 3.6 million years ago, during the Miocene period until the end of the Pliocene.
The megalodon is often compared to the great white shark, but its dimensions were of a much larger scale. Scientific estimates suggest that the megalodon could reach lengths of up to 18 meters, although some studies propose even more impressive measurements. Its teeth, which are one of the main sources of knowledge about the species due to their durability over time, could exceed 18 centimeters in height.
The magnitude of the megalodon is not just a matter of size, but also of ecological impact. As a super predator, it would have exerted a significant influence on marine ecosystems, shaping the evolution of other species and the dynamics of oceanic food chains. The extinction of the megalodon, the causes of which are still debated among scientists, marked the end of an era in the history of marine life.
Frequently Asked Questions (FAQ)
1. Is the megalodon the same as the great white shark?
No, although they are often compared, the megalodon and the great white shark are distinct species. The megalodon was much larger and lived in an earlier period.
2. How do scientists know about the size of the megalodon?
Scientists use the size of fossilized teeth and comparisons with the anatomy of modern sharks to estimate the size of the megalodon.
3. Does the megalodon still exist?
There is no scientific evidence supporting the existence of the megalodon today. The species is considered extinct.
4. Why did the megalodon go extinct?
Theories about the extinction of the megalodon include climate change, a decrease in available prey, and competition with other marine predators.
