Extinctions. — The mammals of this grand life zone have lost nearly 

 all resemblance to those of ITpper Pliocene times with the exception of 

 the survival of the etrascan rhinoceros and possibly of the sabre-tooth 

 tiger. The polycladine deer of Upper Pliocene times and of the ^N'orfolk 

 Forest Bed, or First InterglaciaL have vanished: neither are there any 

 traces of the axis deer (C axis). 



Arrivals. — The Second Interglacial Stage is readily distinguished both 

 in France and Great Britain by a number of important new arrivals, 

 chief among which are the ^'old elephant" {E. antiquus) and the broad- 

 nosed rhinoceros (D. raerckii). Another very important arrival is the 

 lion related to the African Felis leo. The southern elephant has now 

 certainly passed into the Eleplias trogontherii .stage of Pohlig for the 

 type specimen of this intermediate species occurs at Siissenborn; in fact, 

 this is the "E. trogontlierii stage** of Pohlig: it is also known as the 

 "'older E. antiquus" stage by Schmidt and other authors. The southern 

 mammoth E. (meridionalis) trogontherii is replaced by the more pro- 

 gressive and typical E. trogontherii. The broad-faced moose {Alces latir- 

 frons). the giant deer (Megaceros) and the roe deer (Capreolus) are all 

 present in the cooler and forested phases of this interglacial period. The 

 true stag (Cervus elapJius) is certainly recorded. The cattle {Bos primi- 

 genius) begin to be numerous and the bison (Bison priscus) also appear 

 in numbers. Horses of larger size occur (E. rnoshacJiensis, E. siissen- 

 tornensis) . 



Among the river-living forms are the beavers (Castor). The giant 

 beaver (Trogontherium) is by some authors said to make its last appear- 

 ance in Europe in this sub-stage, but it is again recorded in the Third 

 Interglacial at Chelles. Other rodents include the marmots (Marmotta) 

 now found in the Alps, Carpathians and Pyrenees, whose remains may 

 have been borne down by the streams. Beside the lions the carnivores 

 include the typical Eurasiatic forest forms, namely, the lynx (F. lynx)^ 

 two varieties of bear (TJ. deningeri, U. arvernensis). and the badger 

 (Meles).
