Geography
Country: Saudi Arabia
Coordinate: 27.45° N, 39.42° E
Coordinate basis: estimated from map
Time interval: Middle Pleistocene
Max Ma: 0.554
Min Ma: 0.473
Age basis: ESR
Geography comments: "approximately 95 km southeast of the city of Tayma" (coordinate estimated from the map in Fig. 1)
from the local Unit 5
there are combined US-ESR dates of 473 +50/-33 and 554 +79/-76 ka
there are also standard U-series dates indicating a younger age, but they are apparently rejected by the authors

Environment
Lithology: sandstone
Taphonomic context: fluvial deposit
Habitat comments: "weakly cross-bedded, very poorly sorted, coarse, reddish sands" representing "continual localised slopewash events" and not lacustrine or channel environments
Methods
Life forms: carnivores,ungulates,birds,lizards
Sampling methods: quarry
Sample size: 279 specimens
Years: 2013, 2014
Sampling comments: most specimens are from excavated trenches
TAG/13 and TAG/14 specimen numbers appear to represent 2013 and 2014 collections because illustrated specimens from trench 1 in Fig. 2 both have the same prefix
