I prescribe to the idea that dinosauroids/trodoons may have eventually split between their original avian-esque form and humanoids
The question then is "do these trodoon men actually have humanlike behaviors?"
If the answer is no and they are essentially still closer to birds/reptiles than primates, then we'd essentially have humanoid birds walking around. Better able to use tools than birds currently are, but not quite enough to form civilizations as we know them where mass organized trade would be a major problem. Though I would like to think they'd manage a certain form of it that, with enough environmental pressure, could allow them to easily become humanlike in behavior over time, perhaps after another few million years from now.
Wow, I don't know why that thought just blew my mind: thinking about what evolution would have wrought if humans never rose to the level we're at now. Like if Erectus was about as well as our line ever did.
If the rise of this sapient species happens barely 20 million years after what would have been the KT Extinction event, then there's no reason why Earth today and everything within about a 40-million-light-year diameter wouldn't be a post-Singularity cage. Who knows, maybe we are in one and our timeline where primates rose instead of dinosauroids is one of many simulations to see how long it would take for sapience and the Singularity to re-emerge in the event that the Chicxulub asteroid either managed to kill off all non-avian dinosaurs or actually managed to hit Earth. Even if this species failed, enough time has passed that certain resources could've been replenished. 50 to 45 million years is a very long time, after all, and most land-dwelling plants didn't actually evolve until much more recently than you think.
