Lothagam - Apak Mb., Kenia

Fundort:	Lothagam - Apak Mb., Kenia, , Kenia
Taxon:	Cercopithecoides kerioensis aus der Familie Cercopithecidae
Fossilien und Beschreibung der Fundstelle:
Macrofossils,mesofossils, K-Ar dating constrains the base of the Apak Member to be older than 4.22 +/- 0.03 Ma (from altered pumices 35 m above the base of the Apak Member) and younger than about 5 Ma (4.9 Ma is suggested). The top of the Apak Member is the Lothagam Basalt, which has been dated (K-Ar) to 4.2 +/- 0.03 Ma., The Apak Member encompasses sediments overlying the Purple Marker of the Upper Nawata and beneath the Lothagam basalt. It is characterized by thick upward-fining cycles. Lithologies are 71% sandstone and 29% mudstone. Sand bodies are typically single-storied, dominated by a coarse quartzofeldspathic sand at the base, and fining upward to a pedogenically modified mudstone. In the southern exposures, the upper part of the member includes lacustrine strata with abundant fish remains, probably reflecting the development of the Lonyumun Lake at ca. 4.1 Ma. Mammalian faunas are not abundant in the member.
