Aerosteon

Aerosteon riocoloradensis from the Late Cretaceous of Argentina. It is known from a partial skeleton (skull reconstruction and images seen on the web [as well as here], are all hypothetical as only a few bits and a tooth have been recovered from the skull). Some of the bones including the furcula, the ilium, vertebrae and the gastralia, show pneumatisation (air-filled spaces) indicating that this theropod might have had air-sac systems allowing them to breathe like modern birds. It also appears to be an allosauroid, a group that so far has never been found in the Gondwanan late Cretaceous.

In the report I´ve read about it it´s said to be covered in feathers :?

Well, it was a german report, so maybe they just made a translation mistake.

No, that's an allosauroid and these weren't covered with feathers. But their bones show a degree of pneumatisation suggesting that they were breathing like birds.

Oh, okay.
Then they must have made a mistake (I already wondered why the feathers were not mentioned in the original english report).

oops! I misunderstud what you have right! my mistake :$

Nop! they are not (accurate) records of allosauroids in the late cretaceous! Sorry, my mistake! :D

Allosauroids have been already reported in Gondwana, since the 30's! in fact Carcharodontosaurids are Allosauroids my friend! Anyway, Aerosteon doesnt seem to be a member of the Carcharodontosaurids, it might represent a yet unlnow lineage (unfortunately, sereno et el didnt provide any phylogenetic analisis from this guy, they focused the paper in the "air sacs" stuff)

Sereno...is an idiot.

you're fast!!!

good work!!

Oh, a comment. Since you use photographic backgrounds, you may check programs such as Terragen. Is somewhat easy to use and gives fantastic results... Other free software is L3DT, but I haven't used it yet...

Thanks for the tip. I should try this.
