Hundreds of square degrees have been mapped at submillimeter wavelengths and notwithstanding the negative K-correction in the submm bands, where there is no significant loss of sensitivity to the detection of these sources up to z~10, only a handful of sources have been confirmed to lie at z>5 and only two at z>6. All of these SMGs are rare examples of extreme starburst galaxies with star formation rates (SFRs) of >1000 M_sun/yr and therefore are not representative of the general population of dusty star-forming galaxies. Consequently, our understanding of the nature of these sources, at the earliest epochs, is still incomplete. Here we report the spectroscopic identification of a gravitationally amplified (mu = 9.3 +/- 1.0) dusty star-forming galaxy at z=6.027. After correcting for gravitational lensing we derive an intrinsic SFR of 380 +/- 50 M_sun/yr for this source, and find that its gas and dust properties are similar to those measured for local Ultra Luminous Infrared Galaxies (ULIRGs), extending the local trends up to an unexplored territory at high redshift. This ULIRG-like galaxy at z=6 suggests a universal star-formation efficiency during the last 12.8 Gyr for dusty star-forming galaxies.
