Abstract

Inclusions in amber and copal provide us with a unique insight into terrestrial palaeocommunities because they represent a palaeobiocoenosis: a naturally co-occurring group of organisms that perished at they same point in time and in the same place. We report the first (sub)fossilized example of a spider population, preserved in Colombian copal, which has been dated back as far as 1736 /- 35 years. The specimen contains 26 spiders belonging to the Euryopis/Emertonella genus complex (Theridiidae). Such subfossils in copal provide exciting new research opportunities in molecular palaeobiology for investigating changes in genetic variation within a group at the threshold of ecological and evolutionary timescales.
