An Nafud desert, Locality 2 (Pleistocene of Saudi Arabia)

Also known as An Nafoud

Where: Saudi Arabia (27.1° N, 39.1° E: paleocoordinates 26.9° N, 38.9° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Pleistocene (2.6 - 0.0 Ma)

• The faunal remains come from lacustrine deposits which overlie an ancient dune system and the Middle Miocene Ajfar Formation.

Environment/lithology: lacustrine; siltstone

• The lacustrine deposits fill concave depressions on top of the old white eolian sand and are commonly covered laterally by the present dune system; this indicates that they were formed in several isolated lakes which were probably not synchronous.
• The bones from locality 2 come from a thin siltstone layer interbedded between the ancient eolian sand and a dm-thick bed of of lacustrine carbonate.

Size class: macrofossils

Collection methods: Locality 2 was discovered in 1995. A total of 'a few hundred specimens' have been recovered from the three localities together.
