Hoy te tenemos un video especial elegido por nuestros mecenas de Patreon. En este, exploraremos a los tiburones más raros del registro fósil. Veremos depredadores gigantes, tiburones sin escamas, tiburones con grandes espinas, gigantescos comedores de animales con conchas, algunos con formas de anguila e incluso, unos con aspecto “peludo”. Todo eso y un poco más en este video.
