[dinosaur] Hypothetical dinosauroid civilisation

Good day to all listmembers, I have an unusual question regarding hypothet=
ical civilisation of highly intelligent dinosaurs, or "dinosauroids". Woul=
d it be possible for us to find some traces of late Cretaceous civilisatio=
n similar to - say - human societies of late Pleistocene (late stone age)?=
 What would be its most remarkable traits (markers) in the fossil record? =
Thank you for your thoughts!
