Unravelling Ancient Giants: The Evolution and Mystery of the Megalodon

Learning objective

What do you already know about the megalodon and its evolutionary history?

Introduction to Evolutionary Research

Evolutionary research studies life's history through fossils, genetics, and comparative anatomy to understand species changes over time.

Meet the Megalodon

The megalodon was a massive prehistoric shark, believed to have lived around 23 to 3.6 million years ago, measuring up to 18 metres.

Fossil Evidence

Megalodon fossils primarily include teeth, which are up to 18 cm long, providing insights into their size and diet.

Theories on Extinction

Megalodon extinction theories include climate change, prey scarcity, and competition with other predators like great white sharks.

Comparative Anatomy

Comparing megalodons with modern sharks helps scientists understand their evolutionary adaptations and ecological roles.

Genetic Research

Though no DNA of megalodons exists, genetic studies of related sharks help infer evolutionary lineage and traits.

Implications of Research

Studying megalodons enhances our understanding of marine evolution and informs conservation strategies for modern sharks.
