Paleoenvironmental reconstruction of the Last Glacial Maximum, inferred from insect fossils from a tephra buried soil at Tempest Lake, Seward Peninsula, Alaska
Sediments and vegetation dated 21,570 cal yr BP were buried under tephra on the northern Seward Peninsula. This buried surface has yielded plant macrofossils in growth position, as well as numerous insect excellently preserved in permafrost. It appears that many of the insects were buried alive by t...
