Abstract
Eleven fossil dicot woods belonging to three families are described
from the Oligocene of the Cairo Petrified Forest protected area.
Andiroxylon aegyptiacum sp. nov. is described as a new species.
Copaiferoxylon matanzensis, Dichrostachyoxylon palaeonyassanum,
D. royaderum and D. zirkelii are reported for the first time from Egypt.
Afzelioxylon welkitii, Mimosoxylon tenax and Terminalioxylon
edwardsii are described for the first time from the Cairo Petrified
Forest. The three remaining species; Bombacoxylon owenii,
Cynometroxylon tunesense and Detarioxylon aegyptiacum had already
been described previously from several sites in Egypt including the
study area. Affinities of the reported species are given based on
comparisons with related fossil woods described earlier from Egypt
and from other countries.
Climatic interpretations are then obtained from the anatomical
features of all the fossil taxa. Moreover, the relationships and
comparisons with the nearest living relatives are discussed. Finally,
evidence for the origin of legumes from Africa is provided with some
inferences on the palaeophytogeography.
