Ancient Megalodon Nursery Revealed by Panama Fossils

Ancient Megalodon Nursery Revealed by Panama Fossils

This study provides the first definitive evidence of nursery areas for Megalodon during the late Miocene in Panama. Fossil teeth indicate that juvenile sharks used these areas as vital habitats approximately 10 million years ago.

    @Z3nDea @TylerGreenfieId Sadly, there will always be conspiracy theorists & cranks who won't acknowledge any evidence against the nonsense, no matter how solid. So indeed good to have papers stating the obvious. See also these 2 papers on Meg extinction: https://t.co/EtTG6DSV5j https://t.co/YQEgVQ7suG

    @AdamRShannon @JacquelynGill @alexantra For most analyses, we do assume that a species goes extinct immediately after its last appearance, as Dr. Gill states. But some analyses attempt to quantify the gap between the last appearance & true time of extinction. e.g.: https://t.co/95c2PfPBZ9 by @pimientoc & @ExpEcoCons

Abstract Synopsis

  • Carcharocles megalodon, the largest shark ever, likely went extinct around 26 million years ago during the Miocene epoch, based on recent fossil analyses.
  • The study used a new method called the Optimal Linear Estimation (OLE) model to more accurately date its extinction, filling a gap in previous research.
  • The extinction of Megalodon predates the rise of modern large filter-feeding whales, providing insights into how the removal of apex predators can influence marine ecosystems and their evolution over time.]
