Please help identify plant with tiny yellow flowers

Here is a plant that grows about two to three feet all and has masses of tiny yellow flowers. The blooms are about the size of a pencil eraser and have many, many petals. Sorry the picture is not very good and does not really show the blooms up close. It is in a pasture and attracts a very pretty orange butterfly that looks like a member of the Danaus family. Thanks for any help.

 

Probably, Euthamia caroliniana.

 

Thanks for your reply. It does look like my plant is Euthamia caroliniana.
