Description
It's been a while since my last post. This was done with just Poser, some use of the Hair Room and a bit of Photoshop.
Buitreraptor was a small dromaeosaur and so related to other dinosaurs like Velociraptor, Deinonychus and so on. It was smaller and had a much longer snout than Velociraptor.
βBuitreraptor is from the early Late Cretaceous Candeleros Formation (Patagonia, South America), dating to the Cenomanian-Turonian, about 94 million years ago, when South America was an isolated continent like Australia today. It was uncovered in a famous fossil site named La Buitrera, the "vulture roost". Although dinosaurs are rare in this site, another nearby site had earlier yielded Giganotosaurus, one of the largest known carnivorous dinosaurs.β
Judging from the teeth and forelimbs and likely the animal's small size, it hunted small mammals, lizards and the like. It was only about 4 feet long, about the size of a rooster with a long tail, and was most likely feathered. Though the fossils found do not have any skin impressions, most other dromaeosaurs have shown to be feathered, so it would be more unusual if it was not.
Buitreraptor shared the landscape with one of the largest predators of all time, Giganotosaurus, as well as a couple of long necked sauropods. The formation it was discovered in has not revealed many dinosaurs, but is better known for numerous common reptiles such as lizards, crocodillians, snakes and turtles.
Thanks for stopping by.

Why are there fingers sticking out of the wings? Look at birds. They have feathered hands, and have primaries. The hands should pretty much be non existent.

That's simply not the case with this species. They have three fingered hands for holding and probably grasping. The fossil finds show prominent hands and fingers. Though Dromaeosaurs had feathers, they were still non avian dinosaurs.

Actually, that makes zero sense. being there for grasping doesen't mean that primarys and feathers attached to the wings. they can kinda clutch with their fingers, and that's it.
and the excuse " they were still non avian dinosaurs." doesen't mean anything either. all because they are not birds doesen't mean that they have many bird like qualitys, and by today's standards, would still be considered birds. and yes, birds DO have fingers. we have many direct evidences from many dromaeosaurs that having primaries on their hands is about as common as they were with birds.
all because it has fingers doesen't mean that they could not have primaries. all of the other dromaeosaurs we have with primaries, (Zhenyuanlong, Microraptor, Siornithinosaurus,) all have three fingers.

Regardless, they are actually arms and not true wings. The fossil finds show arms that end in three fingered claws and there is actually no evidence this dino had feathers, but I chose to depict feathers because so many Dromaeosaurs are known to have feathers. That said, the arms and hands of Buitreraptor are not like the three you mention. Perhaps Buitreraptor had long primary feathers, but there is no evidence nor is there purpose for them.

and yes, there are still uses for the primaries. they help in mating displays, thermoregulation, and some have speculated that they use them to attract fish, like modern herons today.

I'd like to add that I am open to alternative ideas and concepts and would never profess to know it all. However your initial comment comes off as antagonistic and arrogant whether you intended that or not.Β

Do you realise that dromaeosaur hands are generally very stiff, and not well suited for grasping? we did know that buitiraptor had stronger arms than most dromaeosaurs, but the general condition is to have bird-like wings, with a propatagium, and feathered hands, and having scaly fingers.Β
What you don't realize, is that wings and feathers on dromaeosaurs were probably as common as they are on birds, therefore, most, if not all dromaeosaurs had both a full set of wings, along with feathers. all because it has three-fingered claws does not mean that it can't have primaries. look at Archaeopteryx, for example.Β
I am sorry if i am coming of harsh, but I suggest you take my words.

Point taken. I defer to your expertise since you know what I realize and what I do not.

Cool!
Also, I'm pretty sure there is a growing consensus that Unenlagians such as Buitreraptor might have been fish eaters.

Interesting! Food for thought. I often forget about fish eaters. Perhaps a long snout would give it an advantage.
