*Paleontologist to be*
Tyrannosaurus Rex was a scavenger and a hunter, most likely, but mainly a scavenger it would seem. Take a look at the skull.

See that really thick bone in the back? That's for crushing bones, and it's similar to what many scavengers had today. Also the bone-crushing, banana-looking teeth seem to be scavenger-like. I don't remember the exact reasoning, but one paleontologist theorized that juvenile Tyrannosaurs would have been hunters, whereas adults would have been scavengers-- if anyone can find more on this, please say.
Anyway, Tyrannosaurus really wasn't much and I wish people would stop giving it so much attention...!
'Raptor' types the most intelligent... Well, let me use their scientific name, just because it makes me feel more decent..... Deinonychosaurs. It's likely that the predatory dinosaurs
were the intelligent ones (they would have to be, if they were to have the skill to ambush and cooperate with others), and the deinonychosaurs seem to have the largest brain cavities. It's likely that they were among the most intelligent of them all, especially Troodon, one of my personal favorites:

Troodon was small and quick, and reputed to be the most intelligent prehistoric dinosaur discovered. Not to mention, it very well may have been omnivorous too!
And about birds and dinosaurs? The most recent, up-to-date, studies show something that evolutionists and dinosaur enthusiasts love. Birds related to dinosaurs? Bah! Birds
are apparently dinosaurs, since they share certain same skeletal structures that were thought to exist
only in dinosaurs. Ah, the joy of science!
If you want any info on Camarasaurus, I can provide
some... The Camarasaurus, name meaning 'chambered lizard' (refering to the hollow parts of its backbones) is a Macronarian, thus a close relative of the more famous Brachiosaurus (which did NOT have nostrils on its forehead!!):

It was a very common sauropod during the Jurassic and likely moved in herds.
