  We have obtained Spitzer Space Telescope MIPS observations of 40 F- and
G-type common proper motion members of the Scorpius-Centaurus OB Association
with ages between 5 and 20 Myr at 24 micron and 70 micron. We report the
detection of fourteen objects which possess 24 micron fluxes >30% larger than
their predicted photospheres, tentatively corresponding to a disk fraction of
>35%, including seven objects which also possess 70 micron excesses >100 times
larger than their predicted photospheres. The 24 micron plus 70 micron excess
sources possess high fractional infrared luminosities, LIR/L* = 7.0e-4 -
3.0e-3; either they possess optically thin, dusty beta Pictoris-like disks or
compact, opaque HD 98800-like disks.
