Gr. Coope et J. Bocher, Coleoptera from the Late Weichselian deposits at Norre Lyngby, Denmark andtheir bearing on palaeoecology, biogeography and palaeoclimate, BOREAS, 29(1), 2000, pp. 26-34
The freshwater sediments exposed on the cliffs at Norre Lyngby northern Jut
land has long been a classical locality for the study of Danish Quaternary
geology, palaeontology and archaeology. These deposits date from the latter
pan of the Allerod period (i.c. G I-I). Samples for insect analysis have b
een taken from both the northern and southern exposures of these deposits.
Ninety-five- taxa of Coleoptera (beetles) were obtained, of which 69 could
be named to species. Of the latter, 23 are not found living in Denmark. tod
ay. Most of these are still living in northern Fennoscandia but one species
is now confined to Mongolia. These assemblages have enabled a detailed pic
ture of the local environment to be reconstructed. showing that the basin-l
ike profile of the deposits represents a section through a channel with slo
wly moving water. It has been possible to quantify the thermal climate of t
he time using the Mutual Climatic Range method indicating that mean July te
mperatures were about 10 degrees C and men January temperatures were about
-12 degrees C. These figures are considered in the context of Lateglacial c
limatic reconstructions obtained from coleopteran assemblages elsewhere in
northwestern Europe.
