Ntumbe area tracksite 2, Chewore (Jurassic to of Zimbabwe)

Also known as Chiwore, Six-Footprint Site

Where: Mashonaland West, Zimbabwe (16.2° S, 30.0° E: paleocoordinates 30.4° S, 4.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Dande Sandstone Formation, Middle Jurassic to Middle Jurassic (174.7 - 145.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: dry floodplain; micaceous, silty sandstone and mudstone

• " The dinosaur footprints were preserved in an overbank adjacent to the river channel in which sediment accumulated during flooding."
• "bituminous midstones that indicate a shallow-water lake (or quiet overbank) sub-environment where crusts of gypsum and possibly halite reflect periodic aridity. Ripple marks and dessication features on alternate beds, and sometimes on the same bed, show that periodic precipitation occurred in this semi-arid to arid environment...The footprints are preserved in a rapidly drying silty sand (indicated by dessication cracks and ripples) and infilled by a softer, more erodible muddy sediment."

Size class: macrofossils

Preservation: trace
