El esp\u00e9cimen hallado es un <strong>ovirraptorsaurio.<\/strong><\/p>\n<p>Estos dinosaurios, que ya contaban con un gran parecido a las aves de nuestra era, vivieron hacia el final del Mesozoico, durante el periodo Cret\u00e1cico. <strong>Fueron parte de los \u00faltimos dinosaurios que vivieron sobre la Tierra.<\/strong><\/p>\n<p><strong>El f\u00f3sil tendr\u00eda una antig\u00fcedad d 70 millones de a\u00f1os.<\/strong> Se trata de un esqueleto posado sobre un nido donde incubaba 24 huevos.

Esto refuerza la hip\u00f3tesis de que algunos dinosaurios acaso ten\u00edan un involucramiento cercano al que ver\u00edamos hoy en d\u00eda con las especies de aves que empollan.<\/p>\n<blockquote><p>\u201cAqu\u00ed reportamos el hallazgo del primer f\u00f3sil no aviar de un dinosaurio conocido por preservar el esqueleto de un adulto sobre un nido que contiene restos de embriones. La posici\u00f3n relacional conservada del adulto con el nido, junto con las etapas avanzadas de crecimiento de los embriones y sus altas temperaturas de incubaci\u00f3n estimadas, proporciona un fuerte apoyo a la hip\u00f3tesis de la.
