What evidence would we expect to find if dinosaurs had deveoped technology?

[John J]

This question has bugged me for years and I don’t have a clue what the answer might be, although I have been told that it’s the premise underlying several science fiction novels (none of which I have read).

Dinosaurs were the dominant life form on earth for about 160 million years before being wiped out by (we think) a meteorite impact 65 million years ago.

Mammals have been around for the 65 million years since the extinction of the dinosaurs, but it’s only over the last few hundred of those 65 million years, one species of mammal (we, Homo sapiens) has developed technology.

So this is my question: If a single species of dinosaur had developed similar technologies to us in the last few hundred years of their 160 million year reign, what evidence for it might we expect to uncover now?

Or, to put it another way, if a giant meteorite were to strike earth tomorrow and wipe us all out, what evidence of our existence would still be around in another 65 million years?
