Importance of Dominican Republic amber for determining taxonomic bias of fossil resin preservation—A case study of spiders

Fossils preserved in amber represent only a small fraction of the biota which was alive in the amber forest. In order to make accurate palaeoenvironmental reconstructions, it is necessary to determine the biases which affect preservation. Only the Baltic and Dominican Republic amber deposits have had inclusions described in sufficient quantities suitable for quantitative analyses. Baltic amber is twice the age of Dominican, with a...
