We present estimated redshifts and derived properties of a sample of 1663 galaxies with Ks= 2.5, the bright end of the Ks-band LF shows no sign of decline, and is progressively well reproduced by the ERGs with increasing redshift. We also explore the evolution of massive systems present in our sample: up to 20-25 per cent of the population of local galaxies with assembled stellar mass M > 1 × 1011 Msolar has been formed before redshift z~ 4, and contains ~45-70 per cent of the stellar mass density of the Universe at that redshift. Within our sample, the comoving number density of these massive systems is then essentially constant down to redshift z~ 1.5, by which point most of them have apparently evolved into (I-Ks)-selected ERGs. The remaining massive systems observed in the local Universe are assembled later, at redshifts z
