Cow pat hunting!!

As an entomologist, half rotted and dried cow pats are a boon! 
poking around in one today at Anchor Bottom near Shoreham I found two of these little beauties!
This is either Aphodius fimetarius, or Aphodius pedellus complicated as they are almost impossible to separate!
They are tiny as you can see from my hand and as the name suggests can be found in all types of herbivore dung.
