68 WYNNE : GEOLOGY OF THE SALT RANGE IN THE PUNJAB, 



The sub-divisions as indicated all possess sufficiently well-marked 

 petrographic characteristics to enable them to be distinguished. If 

 some hesitation on this ground might be felt^, as to the boundary between 

 Nos. 6 and 1 , it would be removed by palseontological evidence: The 

 fact of superposition establishes several of the groups^ but some, though 

 probably related, are so distant from each other that this clue to their 

 place is absent, and when fossils are entirely wanting, as in Nos. 1, 

 2, 4, 5, and 8, their geological age becomes less certain, though their 

 places in the series may give some aid as to their approximate position. 



Of the older groups. No. 3 only has yielded fossils and at but two 



places, where several small shells of the genus 

 Fossiliferous beds. 



Oholus^ Eichw., or SipJionotreta, vern., were 



found by myself and determined by Dr. Stoliczka,t thus indicating an 



age not newer than Silurian. 



In group No. 4, obscure Fucoidal impressions have been met with, 

 but nothing determinable. Group No. 6 abounds with well-known 

 carboniferous species and many new ones according to Dr. Waagen. 

 No. 7 contains quantities of Gastropoda and bivalves of Triassic age, 

 (and some which Dr. Waagen thought might possibly show the lower 

 beds to belong to the continental Dyas). No. 9 has numerous Belemnites 

 and other Jurassic fossils as recognised by Dr. Waagen and previous 

 observers. No. 10 has furnished but scanty and obscure palseontological 

 evidence, while No. 11 is full of ill-preserved nummulitic fossils, and 

 the tertiary sandstones, &c,, above frequently contain mammalian bones, 

 crocodilian and other remains. 



Perhaps the most remarkable fact relating to the fossils found in 



^ , .„ . the Salt Rane-e is the discovery of true Ammonites

Dr. Waagen himself (See Mem. Geol. Surv. India, Vol. IX, pt. 2). It

f Dr. Waagen has seen these fossils in situ and cleared some specimens for further 

 determination, but did not decide to which of the two genera they belonged, so far as I am 

 aware.
