How would it deal with a large booger?
Snort it out?

It would be interesting to study the evolutionary process which led to T-Rex having short arms. What "natural selection" gave the advantage to bipedalism?

Think about an ostrich. They have virtually useless wings (which might be equivalent to the "short arms" of a T-Rex), and their primary mode of locomotion is bipedal. They go pretty fast on the savannah, and those legs are excellent weapons, too.

Maybe T-Rex was on that evolutionary path?

That's an interesting idea. Maybe the T-Rex is the direct ancestor of the ostrich. In which case, I'm keeping well out of the way of ostriches! :lol:

Not even the toe bones, but the bones of its instep? To pick it nose? Doubt it.

The could have independently evolved the same trait. Though ostritches are descended from the same critters as all birds which are small two legged carnivorous dinosaurs related to, and contemporary with T-rex.

That is interesting! Birds are a bit scary though 8O

It was a joke. If you look at modern birds they simply wipe their beaks on the nearest surface

My understanding is that Ostriches evolved from the same branch of dinosaurs that gave rice to raptors. A modified version took to the trees and developed feathers called archaeopteryx and they evolved into all birds we know including Ostriches.

Ostriches originated the pimp strut. :D They are also mean.My ex stupidly stuck his hand over the fence to pet one and it pecked the hell out of him.
I’m glad it did, served the idiot right.
I’d pay good money to see that again,except with more ostriches pecking and he’s inside the fence. :twisted:

Ostriches have evolved to be aggressive due to the plains of Africa being a somewhat dangerous place, In contrast Australian emus are relatively tame and even kids feed them. However the odd emu is enamoured by bright colours so if you have light coloured eyes you need to be careful the emu doesn't take an interest and peck.

/\Turkeys will also peck at shiny objects, rings ,rivets on jean pockets and small children’s eyes.

Emus don't always take things lying down!

The emus stalemated the whole Australian army in a several years long guerrilla war! Granted the 'kill ratio' was in the humans' favor. But the emus DID take out one of the Aussies' Humvees (actually a 1930's equivalent of a humvee) in a suicide charge (kinda like Pickett's Charge at Gettysburg).
