PALEONEWS: Megalodon cambia de forma

Un nuevo estudio sugiere que la forma de megalodón ha sido inferida de manera incorrecta y propone nuevas líneas de evidencia para acercarnos más a la verdadera forma que tuvo este, el depredador marino más grande de todos los tiempos. Si quieres enterarte de qué va esto, no te pierdas este video.
