fossils found [on Woody Island] were very few; one ap¬

organism like a flattened Dentalium^ but which is prob¬ 
ably a worm

the most con¬ 
spicuous. It is not improbable that these slates are of 
Triassic age, but a final determination will require more 
prolonged study.” 
Professor Alpheus Hyatt reports upon these fossils: 1 
“The slab from Woody Island, Kadiak, has what appears 
to be a large, much compressed species of Posidonomya, 
and I should think it might be Triassic or older, but there 
is no solid basis for this opinion.” 
The fossils from the newer Mesozoic of the Alaska 
and Kenai peninsulas are from rocks of very different 
character from the Yakutat Series. A large slab with 
Monotis salinaria from Cold Bay, west of Kadiak, across 
Shelikof Strait, is lithologically very like the Vancouver 
slates. 
In the same way the limited occurrences of Paleozoic 
fossils in Alaska are in limestones and rocks very unlike 
those here under discussion. 2
