A piece of silicified fossil wood was found in the middle part of the Red Sandstone Group of the Songwe-Kiwira area, north of Lake Malawi (Nyasa) in the Western branch of the East African Rift System. It is identified as Pahudioxylon Chowdhury et al., 1960. Until now, Pahudioxylon is strictly restricted to the Cenozoic. The occurrence of Pahudioxylon in the red beds Formation supports a Cenozoic (Miocene) age rather than a Mesozoic age for this Formation. Comparison with a collection of modern species gives information about the environmental conditions of deposition of the Red Sandstone Group. A discussion follows on the significance of the Red Sandstone Group during the Rukwa-Malawi rift development.
