N2 - We present spectroscopic observations for a sample of 36 Herschel-SPIRE250-500 μm selected galaxies (HSGs) at 2 2 HyLIRGs in the literature, which are detectedserendipitously or via tailored surveys searching only for high-zHyLIRGs; therefore, we can place lower limits on the contribution ofHSGs to the cosmic star formation rate density (SFRD) at (7 ± 2)× 10-3 M ⊙yr-1 h 3 Mpc-3 at z ~ 2.5,which is >10% of the estimated total SFRD of the universe fromoptical surveys. The contribution at z ~ 4 has a lower limit of 3× 10-3 M ⊙yr-1 h 3 Mpc-3, gsim20% ofthe estimated total SFRD. This highlights the importance of extremelyinfrared-luminous galaxies with high SFRs to the buildup of stellarmass, even at the earliest epochs.
