The feeding ecology of megalodon appears to have varied with age and between sites, like the modern great white shark. It is plausible that the adult megalodon population off the coast of Peru targeted primarily cetothere whales 2.5 to 7 meters (8.2 to 23 ft) in length and other prey smaller than itself, rather than large whales in the same ...
Meg 2: The Trench hits theaters this week with a larger-than-life depiction of the megalodon. Here’s what we actually know about the beast, according to scientists.
One of the most striking fossils around today are the teeth and reconstructed jaws of the megalodon.The jaws of the extinct shark are so big, one or two people can stand inside them.

For known DNA sequences, restriction enzymes that cut the DNA on either side of the gene can be used. Gel electrophoresis then sorts the fragments according to length. [20] Some gels can separate sequences that differ by a single base-pair. The DNA can be visualised by staining it with ethidium bromide and photographing under UV light.
