We have developed a technique to identify dense cold cores in star-forming regions using 160 micron image data from the Spitzer Space Telescope in combination with 100 micron IRAS data. We apply the method to the 44 square degree Taurus Legacy Survey to produce an image of emission from cold dense cores, and further produce a catalog of cores covering the entire Taurus region. The 160 micron cold cores are an excellent tracer of dense gas and dust, and correlate well with high extinction (Av > 4) and submillimeter continuum emission. We compare the distribution of known YSOs and new YSO candidates with the cold cores. Most class I and flat spectrum sources are spatially coincident with a cold core. However, most 160 micron cold cores in Taurus are starless. We discuss some of the implications for dense core lifetimes.
