In this study, Megalodon teeth consistently showed some of the lowest δ⁶⁶Zn values across the entire fossil dataset, placing them at the very top of the marine food web. The researchers also ...

Nature Not just sharks and whales: giant megalodon’s true prey finally revealed A recent study has shed new light on the apparent eating habits of the megalodon, an extinct shark that dominated ...

To figure this out, scientists looked at the isotope signatures in megalodon teeth. They looked specifically at zinc-64 and zinc-66, common zinc isotopes which are absorbed when animals eat.

Overall, these new methods have begun to rewrite the history of megalodon’s eating habits and may help to explain more about why these giants of the food chain went extinct. “ [Determining zinc ...

The massive megalodon was not hunting only large marine mammals such as whales as researchers widely thought, a new study of minerals in fossilized teeth has found.

Accordingly, the tissue of fish that eat fish absorbs significantly less zinc-66, and those which, in turn, hunt them for food absorb even less. That is why Otodus megalodon and its close relative ...

Based on one such spinal skeleton of the megalodon, a new study published in the journal Palaeontologia Electronica reports that the giant shark stretched 54 feet in length, or about the size of ...
