Mediterranean 

 shorelines 



Postglacial. 



Monastirian Stage, 

 15-20 meters. 



Tyrrhenian Stage, 

 30-33 meters. 



Quaternary formations of the British Tsles 

 f 25 - foot marine terrace. Scotland, sub- 

 merged forest, peat ; modern marine 

 fauna : early Neolithic. [This ranges in 

 altitude from about 35 feet above sea- 

 level down to and slightly below sealevel 

 i W. B. Wright. 1914.1).] 



r 50-foot marine terrace, Scotland. English 

 Channel : many British species and 

 some arctic. 



J IV Glaciation = Mecklenburgian-Wiirin- 

 ian. restricted to highlands ; great val- 

 ley glaciers, some piedmont : terminal 

 moraines strong and fresh. 



100-foot marine terrace. Scotland, not yet 

 recognized in England and Ireland, on 

 "upper Boulder-clay'' and in fiords. Ex- 

 treme arctic fauna. Pecten grcenlandicus, 

 Yoldia arctica. Tellina myopsis. 



Ill Glaciation = Polonian-Rissian. not so 

 extensive as II. Saxonian - Mindelian, 

 "upper Boulder-clay." 



Interglacial marine gravels of Holderness. 

 Yarmouth, Speeton. etcetera : 30-meter 

 shoreline of Sussex, 



Ireland : high shell beds = reworked 

 erratic deposits of Saxonian stage. 



Holderness : modern British marine 

 fauna. 61 species, with temperate forms 

 Cytherea chinoe, Venus gallina, and 

 fresh-water shell of warm climate, Gor- 

 bicula fluminalis, estuarine; near Yar- 

 mouth, fauna (80 species) largely Brit- 

 ish, some Mediterranean forms : Turri- 

 tella incrustata, Limopsis pygmwa, Car- 

 diff/ cordis, Cytherea rudis; a more tem- 

 perate sea than the modem English sea. 

 Scotland : sand, gravels, clays, marine 

 shells. Interglacial marine deposits with 

 temperate fauna = Tyrrhenian Stage of 

 Mediterranean.
