Fossil history of the Menispermaceae (Ranunculales)
Jacques, Frederic M. B.1,2
AbstractThe Menispermaceae family (Ranunculales) includes more than 500 extant species. Climbers represent the majority of this family, and these plants are now distributed in all of the tropical and Subtropical regions of Americas, Asia and Africa. Their endocarps show a characteristic shape that is easily identified in the fossil floras. Numerous fossil leaves are also mentioned in the literature, but the methods for identifying these fossils are often outdated and need revision. Four tribes of Menispermaceae are present in the fossil record, including Fibraureae, Menispermeae, Pachygoneae and Tinosporeae. Only the Anomospermeae are potentially lacking. The Menispermaceae appear in the Palaeocene, and are common in the Eocene, of Europe and in North America as represented by endocarps and locule-casts. The species of this age show morphological diversification, corresponding with the current familial diversity. A few specimens from the Cretaceous period could be part of this Angiosperm family. Fossils after the Eocene are scarcer, despite several relatively rich outcrops. The maximal expansion of the Menispermaceae during the Palaeocene/Eocene limit correlates with the thermal optimum of the early Tertiary and also parallels the maximal expansion of tropical and subtropical floras. The relative richness of the Eocene era in Menispermaceae could be a consequence of more intense sampling in some regions. The bias in tribe representation can be explained by evolution, ecology or taphonomic hypotheses. (C) 2009 Elsevier Masson SAS. All rights reserved.
