FAUNAS OF SOUTHEASTERN ALASKA REY) 
1,500 feet. The highest member of the Paleozoic section in south- 
eastern Alaska is a limestone of Upper Carboniferous age, probably 
the equivalent of the Gschel-stufe. At the only locality where the 
top of the Upper Carboniferous has been definitely located a lime- 
stone of Mesozoic age rests unconformably upon it. A series of beds, 
mostly limestones, having a thickness of not less than 800 feet, repre- 
sents the Upper Carboniferous portion of the section. 
The several faunas show comparatively little resemblance to the 
faunas of eastern America, while the similarity to the European and 
Asiatic faunas is in some cases very marked.
