We study 87 extremely red objects (EROs), selected both to have color redder than and to R - [3.6] = 4.0 have confirmed spectroscopic redshifts. Together, these two constraints result in this sample populating a fairly narrow redshift range at. The key new ingredient included here is deep Spitzer Space Telescope 0.76 < z < 1.42 Infrared Array Camera (IRAC) data. Based on color, we demonstrate that it is possible to classify [3.6] - [8.0] EROs as early-type galaxies, dusty starburst galaxies, or active galactic nuclei (AGNs; power-law types). We present ultraviolet-to-mid-infrared spectral energy distributions (SEDs) and Advanced Camera for Surveys (ACS) images, both of which support our simple IRAC color classification.
