And of course, Serbian ancient dino-pets :)

*for non-serbians: there is a strong pseudo-scientific move in all Balkan countries that "proves" that all known civilization originates from Balkan nations. The most extreme among them are connecting the ancient Vincha Culture with today's nations.

The second question is the origin of Slavs. Written records originate from the VI century and suddenly, entire Eastern Europe is Slavic. What happened before - well there are at least 5 good ideas about it, without the complete consensus in scientific community.

This is the reason why I pointed out that nothing dramatical was observed in the production of metals during the period of Slavic arrival. Have they arrived at all?
