I like to refer them as 'Homo Dinosaurs'

They'd likely evolve a gait somewhere between the typical theropod horizontal bipedalism and the typical humanoid gait, kind of like the older restorations of theropods where they kinda looked like kangaroos

I'm no expert in the subject, but that's only if having a tail (or similar structure) is still an advantage. If the creatures started becoming intelligent, then they'd likely try to get upon the ground settlements where they can spread out easier and collect food - possibly even becoming hunter-gatherers like ancient humans. Their tails would likely become of little use for balance when they become decent at walking on two legs. The extra height you can get by having a smaller tail would likely eventually cause it to become a vestigial trait.

Just look at the predicament of the human eye and birth canal

Are you talking about the photoreceptors in the human eye being reversed? I am also unfamiliar with the birth canal predicament although I'd probably guess that it is to do with the mortality rate. Could you elaborate?

First thing; yes, among other issues. Second thing: birth is painful. It's almost too narrow, and in many cases it is impossible.

The reason humans take so long to mature is because we come out of the birth canal with underdeveloped brains. Sapient dinosaurs, on the other hand, would most likely still lay eggs.

They would have to evolve to become more social as intelligence can only develop with society as well. They would likely become warm-blooded as relying on the sun would be a great deterrent for exploration causing those who stayed in a single area to eventually die of a natural disaster. Those who became less reliant on external sources would be able to travel more, making colonies along the way which causes the gene for travel much more likely to survive long-term. That might just be enough for warm-blooded animals to develop. Their increased travel would give greater wealth which would allow them to have the spare energy to produce it's own body heat - meaning that it could evolve. It isn't exactly known how warm-blooded animals evolved so the transition being possible is iffy at best.

Dinosaurs were already warm blooded

True but any life on a foreign planet would likely have been cold-blooded first. Or have I accidentally merged two different conversations on evolution? XD
