Resume on the Cloverly seen at type 2nd at Thermopolis. Rusty beds + Greybull obviously are Fall River equivalent. The Rusty beds and Greybull are not separable, because Greybull = local ledge-forming sands in lower part, locally may be all of Rusty zone - viz {rusty} {rusty} {greybull} Disconformity sharp at type Cloverly, not so in Thermopolis road cut where seems to be set up similar to Lee's Bellevue locality with SS + IB var clstu at base. Type Cloverly is in claystone phase. Darton prob. included no Greybull or Rusty in original Cloverly but changed it subsequently - check this against his def. Thermopolis. At type Cloverly little or no Greybull except the local lens, and fairly persistent basal SS 62
