 Qunai (after Powell, 1989).

intertidal environment; it was succeeded by a further pulse officially 

 influenced shallow-marine siliciclastic deposition under similar 

 conditions to those of the Tayan Siltstone further south. 



The pattern of southwest- to west-trending facies belts derived 

 from deep boreholes (Andrews 1991), passing from fluvial and 

 intertidal siliciclastic facies in south Jordan to shallow marine 

 carbonate and intertidal siliciclastic environments in central and 

 north Jordan, is consistent with a progressive onlap during Tayan to 

 Numayri time. The carbonate platform can be traced in the sub- 

 surface of north Syria (Best et al. 1993), a distance of about 700 km 

 from the location of the palaeoshoreline in south Jordan (Fig. 2). The 

 maximum transgression (maximum flooding) resulted in deposition 

 of the main Numayri carbonate in the type area, passing southwards 

 into intertidal and fluvial siliciclastic strata (Wadi Kusheiba Sand- 

 stone). A subsequent regressive low-stand of sea-level (see Regional 

 Correlation, below) resulted in an increased influx of sandy sedi- 

 ment during deposition of the Hanneh unit in the type area. However, 

 boreholes in north Jordan indicate that stratigraphically younger 

 phases of carbonate deposition may have continued in those areas 

 located farther offshore. 



FAUNAS 



Fossils are reported from the following sites: 



1 . WADI ZARQA MA'IN. A section 800 m north of Wadi Zarqa 

 Ma'in (PNG 204.4:501.3) contains thin calcarenite beds. These 

 have yielded: 



'Hyolithes' kingi Richter & Richter, 1941 [type locality] 



Kingaspis campbelli (King, 1923) [type locality; described 



herein] 



Palaeolenus antiquus (Chernysheva, 1956) [described 



herein] 

 'Hyolithes' 1 kingi is apparently identical toHyolithesfouchouensis 

 moabiticus described from the same locality by Picard (1942), 

 presumably in ignorance of the Richter & Richter ( 1 94 1 ) paper. 



2. WADI RIMEILEH, King's (1923) locality A.3 (PNG 201:061 ). 

 1.6 km south of Wadi 'Esal' (=Issal); this is approximately the 

 same locality as Wadi At Tayan (Fig. 3), described herein. From 

 micaceous siltstone: 



Onaraspis palmeri (Parnes, 1971)
