Light and Scanning Electron Microscopic Analysis of Silene stenophylla Seeds Excavated from Pleistocene-Age (Kolyma)
We studied the morphology of ancient seeds of the Silene species (Caryophyllaceae) excavated from feeding chambers of ancient ground squirrels (Geomys, subgenus Urocitellus) burrows buried in the Late Pleistocene Age permafrost deposits of Kolyma lowland (Siberia). The ancient seeds were compared to...

Summary: | We studied the morphology of ancient seeds of the Silene species (Caryophyllaceae) excavated from feeding chambers of ancient ground squirrels (Geomys, subgenus Urocitellus) burrows buried in the Late Pleistocene Age permafrost deposits of Kolyma lowland (Siberia). The ancient seeds were compared to seeds of extant species of S. alba, S. chlorantha, S. nutans and S. stenophylla plants presently growing in the same and neighboring regions. Using Light (LM) and Scanning Electron Microscopy (SEM), the ancient seeds were identified to be of Silene stenophylla (Ledeb.). |
