Moroto II (Miocene of Uganda)

Also known as ETE Locality 540, Moroto Mountain

Where: Uganda (2.5° N, 34.8° E: paleocoordinates 1.0° N, 32.1° E)

• coordinate stated in text

• small collection-level geographic resolution

When: MN 2 (22.4 - 20.0 Ma)

• ETE dating method: time_unit, ETE age comment: 0

•"Fossils have been found at a number of horizons" that are "overlain by a fine-grained basalt that presumably flowed down an ancient channel" and is 40Ar/39Ar dated at "more than 20 Ma" although "isotopic disturbance" makes an exact date impossible; however, a basalt overlying Moroto I is 40Ar/39Ar dated at 20.61 +/- 0.05 Ma [= MN 2] and "it is likely that the basalts represent the same flow" (Gebo et al. 1997)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; medium-grained sandstone and siltstone

• "the depositional environment alternated between fluvial and ponding conditions... Poorly developed paleosols... suggest that sedimentation was intermittently interrupted" (Gebo et al. 1997)
• ETE rock type adj: 0, ETE lithology comments: 0

•"intercalated coarse- to fine-grained sandstone, conglomerate, siltstone, and mudstone... Fossils... are typically associated with medium-grained sandstone and siltstone" (Gebo et al. 1997)

Size class: macrofossils
