Fluvial and deltaic sediments from Jameson Land in East Greenland contain the first record of the leaf beetle Phratora o f. polaris , not presently found in Greenland; the ground beetle Bembidion grapii , north of this species' present northern range limit; and the true bug Nysius gruenlandieus . In addition, there is a rather diverse flora. All of these records are in sediments of Early Holocene age. We suggest that most of these animals and plants immigrated to East Greenland in the Early Holocene by long‐distance chance dispersal, mostly from northwest Europe. The environment was physiognomically similar to that of today, but Salix aretica and Cassiope tetragonu that are important dwarf shrubs today had not yet immigrated.
