Araucariaceae (Pinopsida): Aspects in palaeobiogeography and palaeobiodiversity in the Mesozoic

The paper examines recent information on the history of the 'southern hemisphere' conifer family Araucariaceae and gives supplementary notes to previously published monographs. Important data from the Mesozoic fossil record are presented and summarized to describe the ancient diversity and distribution of Araucariaceae. Information on the origin of the family and oldest fossil records of the present-day genera are assembled. Existing models on phylogenetic relationships within the family inferred from molecular data are compared with relationships between the genera determined from morphological data. Reasons for disappearance of representatives of this conifer family in the latest Cretaceous in North America and Europe are briefly discussed. (C) 2007 Elsevier GrnbH. All rights reserved.
