First occurrence of Icacinaceae fossil flower in amber of Le Quesnoy site (Ypresian, France).

Thomas Haevermans

Résumé

Flowers preserved in amber are rare. In par3cular, the lamiid clade is represented by only one occurrence(Gen3anales) in the Paleogene. Nevertheless, the excep3onal preserva3on of these fragile structures and organs which are usually not preserved in other sediments or deposits, makes these fossils important for understanding evolu3onary processes and past diversity. The locality at Le Quesnoy (Houndancourt, Oise, France) was first exploited in 1999 (Net et al. 1999). This first survey highlighted the abundance of insects and the presence of at least one flower of caesalpinioid legumes in amber. Here, we studied a flower from this site and discussed its systema3c affini3es.
