¡Los T-Rex decapitaban Triceratops!

Nature cuenta que esa fue la conclusión del estudio de cráneos de Triceratops por parte del equipo de Denver Fowler del Museo de las Rocosas en Bozeman, Montana. Él y sus colegas estudiaron numerosos especímenes de la Formación de Hell Creek de Montana y lo concluyeron por la orientación de las marcas  de los T-Rex en los cráneos de sus presas.

Waking the T. Rex: La Historia de SUE

Con 28 años esta T-Rex es la más vieja conocida, con tantos años que vivió se ve que sufrió muchos accidentes realmente serios .... de los mismos que se salvara. Al ser encontrada muchos se pelearon por su propiedad y hasta la subastaron .... para que al fin sus restos acabaran en exhibición! para deleite de todos los que puedan escaparse al Field Museum. ¡Qué bien que Sue tenga su especial en video!

¿Qué le diste a T-Rex por sus 107 años?

¡Está bien vieja Rexie! ... Por cierto, hasta que al fin sale venciendo al que siempre lo derrota en esta clase de videos de dinosaurios

Rey Basura

Hay que ver cuán orgulloso posa con las grandes bestias cazadas el rey Juan Carlos de España.

A ese rey tarado bien que le debió haber caído una visita que lo ponga en su sitio.

Y lo peor es que el sinvergüenza éste es la cabeza de la WWF en España. ¡Se hacía el protector de los animales!

Tyrannosaurus rex

Tyrannosaurus was one of the largest of the "lizard-hipped" carnivorous dinosaurs known as theropods. It was a massive two legged with a powerful tail, large head and tiny arms from the late cretaceous.

About 14m long, 5m tall and 5 tonnes!

Its primary weapon was its mouth, with a 1.2 metre long jaw and a 1 metre gape. Curved serrated teeth, longer than a human hand, could be used to puncture an animal's organs, before Tyrannosaurus tore the flesh off. Tyrannosaurus could not chew, so had to swallow its food whole. It could probably gulp up to 70 kilograms in one go. One fossil shows the danger of this - a large carnivore had died swallowing, with two long bones stuck in its gullet.

In the picture above it is attacking the armored dinosaur Edmontonia and in the following one you can spot a flying Quetzalcoatlus and Pleurocoleus as well.

Its tiny two-fingered arms seemed very small, but were believed to have been at least three times as strong as human arms. They were too short to reach its mouth, but were probably used as meat-hooks. There is clear evidence that tyrannosaurs fought one another from tooth-marks left in fossil remains.

The first reasonably complete Tyrannosaurus skeleton was discovered by palaeontologist Barnum Brown in Hell Creek, Montana, in the USA in 1902. Until this find only fragments had been unearthed. In all, over 20 individuals have been found, although, only three have complete skulls. Remains have been discovered from Alberta and Saskatchewan in Canada,to New Mexico, Montana, Texas, Utah, and Wyoming in the USA. Remains have also been found in Mongolia.

But not everything were those remains... Jeff Anders and Tom Koehnlein did it—a CT scan of a Tyrannosaurus rex skull. The 2,000-pound (908-kilogram) head belonging to Sue, the largest and most complete T. rex ever found, would never fit on an ordinary medical scanner. So Sue went to a Boeing lab in California, where the two engineers spent some 500 hours in 1998 x-raying coin-thin portions of the skull—slicing digitally instead of destructively. “We’d never done anything like it before,” said Koehnlein. The result: new insight into Sue’s senses.

“A Dinosaur Named Sue” appeared in the June 1999 issue of NATIONAL GEOGRAPHIC.

By the way, Sue also knew how to enjoy herself.
