The nature of extremely red objects (EROs, RK > 6) dicovered in deep opticaland nearinfrared imaging surveys is currently unknown.They could be either high redshift dusty starburst galaxies or old elliptical galaxies or dust obscured AGNs.We propose a pilot XMM observation of a small sample of EROs to search forthe hard Xray emission expected if these objects host hidden AGN.This is the most stringent test to verify or to discard the AGN hypothesis.
