Jamdat (Jemdet) Nasr period:

Between Baghdad and Babylon, a discovery was made in 1925 of a distinctive pottery consisting, in the main, of large thick Jars decorated with geometrical or naturalistic designs in black and/or red paint applied directly on buff clay and was found usually in small quantities, on other Mesopotamian sites and as taken as the hallmark of a cultural period immediately preceding history, the so called ‘Jamdat Nasr period’, (3500-3000 B. C.) it had lasted more then three thousand years. However, the cultural elements of that period and those of Uruk period had no fundamental differences, but simple variations in style and quantity.
