It seems that this is Ceratocephala testicular or "bur head buttercup", formerly Ranunculus testiculatus. A small annual weed from Europe becoming widespread in w SD mainly in urban environments (street boulevards, parking lots, picnic/campgrounds, etc.). 

The weed is described art the following SD State Website:
http://www.sdstate.edu/ps/extension/weed-mgmt/weed_description.cfm?weed=Bur%20Buttercup 

A publication from Utah State Extension Service describes this weed and is available at http://extension.usu.edu/rangeplants/htm/bur-buttercup

Typical lawn type broad leaf herbicides that contain dicamba and 2,4-D may be effective. FOLLOW ALL HERBICIDE LABEL DIRECTIONS.  Of course good lawn management can help improve turf density and reduce weed invasion. Treatment should be prior to it setting flowers and seeds if possible.
