*2 Before LOKEN, KELLY, and ERICKSON, Circuit Judges.

____________

PER CURIAM.

Appellants, who are members of the Montileaux family and the Oglala Sioux Tribe, brought this action claiming violations of the Treaty of Fort Laramie of 1868. The district court ^[1] dismissed the action without prejudice for lack of subject matter jurisdiction, and the Montileauxs now appeal. After careful review of the record and the parties’ arguments on appeal, we conclude that dismissal was proper for the reasons explained by the district court. See Buckler v. United States, 919 F.3d 1038, 1044 (8th Cir. 2019) (standard of review). Accordingly, we affirm. See 8th Cir. R. 47B.
