That assumes that intelligent archosaurs were inclined to use fire. If they 
didn't for whatever reason then 
they may not have developed smelting technologies. A lack of metal objects 
doesn't necessarily preclude 
some sort of civilisation (although they'd also lack fired ceramics as well).

It is however possibly to fashion objects out of metals found in their native 
state. Gold, silver and copper 
are the most likely to be found in an already metallic state, but without the 
ability to melt them you would 
be restricted to whittling them down with brute force to achieve the desired 
shape. Inuits fashioned iron 
implements from meteorites using such techniques.

Even if they did make metallic artefacts, after 66 million years it's unlikely 
than anything other than gold 
would still be intact. Any advanced dinosaurian technology that inadvertently 
resulted in nitric and 
hydrochloric acid rain could have accidently created an 'aqua regia' 
catastrophe that wiped out any gold 
artefacts. :-)
