Caption: Figure 4.

Top: spectroscopic evolution of SN 2016dsg. The zero flux levels of each spectrum are indicated by the red ticks. All the spectra have been normalized in the range 4000–7000 Å. Bottom: the NIR spectrum taken at day 16.6. The spectrum has been smoothed with a second-order Savitzky–Golay filter, and the gray background line is the original spectrum. The green band marks the strongest telluric absorptions.
