Abstract
Context. A set of 20 extremely red galaxies at 2.5 ≤ zphot. ≤ 3.8 with photometric features of old passive-evolving galaxies without dust, with stellar masses of ~ 1011M⊙, have colors that could be related to passive-evolving galaxies with mean ages larger than 1 Gyr. This suggests they have been formed, on average, when the Universe was very young (<1 Gyr).
