Wadi Hesban (Triassic to of Jordan)

Also known as Wadi al Hisban

Where: Janoobiah, Jordan (31.8° N, 35.6° E: paleocoordinates 13.7° S, 35.9° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Olenekian to Olenekian (251.2 - 242.0 Ma)

• Originally described as Carnian based on comparison of faunal composition with Raibl and Lettenkohle (Cox 1924), but some uncertainty expressed in this age subsequently, particularly due to the presence of Beneckeia (Cox 1932). Subsequent biochronological work has indicated an Olenekian-Anisian age for this section (Druckman 1974).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; limestone and marl

• "In the neighbourhood of Wadi Hesban the calcareous beds are from 100' to 150' in thickness, but thin rapidly to the east and die out completely within two miles. Thus these fossiliferous beds have the form of a wedge inserted in the Nubian Sandstone. Nearly all the fossils were obtained from the upper half of this calcareous series, which consists of thin-bedded yellow and brownish limestones, 1' to 2' in thickness, separated by beds of calcareous marl of about the same thickness. These marl beds yielded abundant specimens of Coenothyris vulgaris, with lamellibranchs and ammonite fragments. Tile lower half of the calcareous series did not yield any fossils. It consists of grey compact limestone beds 2' to 3' in thickness, separated by rubbly beds composed almost entirely of curiously shaped cylindrical bodies. The exact nature of these cannot be ascertained. They may be of concretionary origin, or possibly casts of annelid tubes. They average 1/2" in diameter, are round or slightly flattened in cross-section, arc straight or curved, sometimes branching, and smooth or with small bosses." (Cox 1924)

Size class: macrofossils

Collection methods: "All the fossils referred to in the description have been presented to the Geological Department of the British Museum" (Cox 1924)
