I think that you may have found beetles in the family Silphidae.  One group
of silphids is black, round, flattish, and with a yellow pronotum with a
black spot in the middle.  Like you said they are a little larger than a
penny.  They belong to the genus Silpha.  They are carrion feeders and are
fairly common (at least here in Michigan).  That would be my best guess.
