CHRONOLOGY. POST-GLACIAL 



Author's Table* 



Cultural Period, Western Europe B. C. 



Neolithic (regionally variable) 7.ooo- 2,000 



Transitional (Azilian, Tardenoisian) 9.000- 6,000 



Magdalenian 14,000- 8,000 



Solutrean 15,000-13,000 



Aurignacian 30,000-15,000 



Mousterian 30,000 



' It is to be iindcrstooti that these dates, though based on the approximations by the fore- 

 most students of the question and many collateral considerations, are given as no more than 

 mere working suggestions. 



Sir Arthur Keith gives a chronology covering the entire human 

 period. The estimates for the postglacial time agree fairly well with 

 those of De Geer and, Antevs ; but the others are necessarily more 

 doubtful. The estimate for the Mousterian period, in particular, seems 

 to need modification ; it appears too short and extends too far forward.

Thanks especially to Drs. Antevs and Leverett, I am able to add 

 several estimates and some notes on the post-glacial time and its re- 

 lation to man. Added also is a chronological table by Osborn ' which 

 embodies some individual views of that distinguished author.
