Des scientifiques redécouvrent des fossiles perdus de Megalodon et révèlent un géant de 79 pieds
vertèbre musée fossile
Plusieurs énormes vertèbres de Megalodon, qui auraient été détruites en 1989, ont été retrouvées inaperçues sur une étagère de musée. Leur analyse renforce la preuve que le requin géant pourrait dépasser 24 mètres (79 pieds) de longueur et vivre près d'un siècle. Les chercheurs estiment également que ses nouveau-nés auraient pu mesurer une taille étonnante de 3,6 mètres (12 pieds).
