Increíble trabajo. Me encantan las comparaciones de este tipo, es curiosa la abundancia de pinguinos en el Mioceno. Y S. megarhamphus destaca no solo por su tamaño, es muy robusto y su esternón me parece que es bastante grande, imagino que debió ser un gran buceador.

Este es el primer esqueleto de megaramphus conocido y es claramente mas grande y robusto que Spheniscus urbinai. Interesantemente, megaramphus es uno de los piguinos mas raros en el Mioceno de Peru y Chile, por lo que aun se desconoce bastante de sus habitos

Spheniscus megaramphus debió ser un ave majestuosa. Su pico ancho me recuerda al del Rhampastosula.

La verdad el pico de megaramphus es mas similar al del pinguino de Humboldt moderno... solo que proporcionalmente mas grande y con un gancho mas prominente. Ramphastosula tiene un pico bastante similar al de un tucan... o un ave del tropico.

Cierto ¿Se sabe a ciencia cierta de qué se alimentaba el Ramphastosula?

La verdad no se sabe mucho sobre la posible dieta de Ramphastosula... es claramente un especialista en items diferentes que los otros piqueros, pero de hecho se desconoce incluso si era capaz de zambullirse como los otros miembros de la familia con ese pico

Yes, I showed him some of this... in fact he is one of my advisers during my PhD that is about the evolution of penguins in South America. This is a figure for one of my next paper.
