Muong Phalane tracksite (middle) (Cretaceous to of Laos)

Where: Savannakhet, Laos (16.7° N, 105.6° E: paleocoordinates 17.5° N, 112.5° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Grès supérieurs Formation, Aptian to Aptian (125.0 - 100.5 Ma)

• lower footprint level, at top of formation

• bed-level stratigraphic resolution

Environment/lithology: "floodplain"; bioturbated, fine-grained, ferruginous, micaceous, argillaceous sandstone

• "related to a flood plain or overflowing channel in a region near a detrital material source"
• "fine-grained sandstone slabs"; "The sediment collected in Muong Phalane is finely detritic. Its mineralogical composition is rich in angular quartz, feldspar, and mica contained in a matrix composed of micritic mud with some claystone and ferruginous pigments. This matrix is subject to an important bioturbation." Middle slab has ripples indicating "rough water"

Size class: macrofossils

Preservation: trace

Collected in 1993, 2005
