Paleontologia

Bello troodóntido durmiente

Aún no nos hemos recuperado de la emoción producida por su tiranosauroide peludo, pero Xing Xu y Mark Norell* acaban de mostrarnos en Nature otra maravilla de Liaoning: un pequeño troodóntido fosilizado con el cuello doblado y la cabeza bajo la extremidad anterior, en la misma postura que adoptan las aves cuando duermen (y que minimiza la pérdida de calor corporal en su cuerpo de "sangre caliente").

El dinosaurito mide 53 cm y su nombre es Mei Long (dragón que duerme profundamente). No os amodorréis; seguiremos informando.

Artículo en Nature News con fotografía del fósil y reconstrucción.
Artículo en español.
