¿Existe realmente Nanotyrannus? (Su historia y debate)
Channel: Palaeos
Date: 2020-01-20

Bienvenidos a Palaeos, la historia de la vida en la tierra.
En esta ocasión les traemos una historia sobre el descubrimiento y todo lo que ha rodeado a Nanotyrannus lancensis, el presunto tirano enano, desde su publicación original de 1946 y hasta este año, 2020, en el que se descubrió algo interesante sobre esta especie. Abordaremos también a Bloody Mary, Jane, Petey y más, mucho más. Así que no te despegues de tu pantalla, pues nos embarcaremos al Cretácico tardío para conocer a este dinosaurio y la controversia que ha suscitado.
