R114 Proconsul site, Kenia


Fundort: R114 Proconsul site, Kenia, , Kenia
Taxon: Ekembo heseloni
Fossilien und Beschreibung der Fundstelle:
Macrofossils, "Lower Miocene... The [Rusinga] Group itself was probably deposited in less than half a million years, and five Potassium-Argon dates for the Group give a mean age of 17.9 +/- 0.16 Ma (Drake et al., 1988). The Hiwegi Formation and site R114 have not been directly dated." Michel et al. 2023: One particularly important result from this work is confirmation of R114's position in the Kiahera Formation (Pickford, 1984) instead of the Hiwegi Formation (cf. Van Couvering, 1972;Whitworth, 1953)., "The infilling green grits are easily differentiated from the surrounding grey tuffaceous flagstones and agglomerates because they are fenetized. Fenite... is commonly found around carbonate volcanic instrustions" "grey tuffaceous siltstone" according to Clos 1995
