Where: Kenya (0.1° S, 35.2° E: paleocoordinates 2.6° S, 31.5° E)
• coordinate stated in text
• local area-level geographic resolution
When: Muhroni Agglomerates Formation, Chattian (28.1 - 23.0 Ma)
• Pickford and Andrews provide radiometric dates for the Muhoroni Agglomerate: 23.5 and 23.6 Ma which they say is Miocene. Harland et al. 1989 place those ages in the late Oligocene.
Environment/lithology: "channel"; massive, volcaniclastic, yellow, calcareous sandstone
•"The Muhoroni Agglomerates are fine to coarse pyroclastic sands with gneissic cobbles and boulders up to 1 m in size, into which ephemeral channels were cut... The deposits range from off-white to yellow and pale brown, and they are at least 10 m in thickness and weakly bedded... Fossil root casts, leaves, and wood are common in the sediments, but vertebrate remains are rare... The channel [yielding the fossils] was filled with unbedded, partially calcified sandstone..." (Harrison and Andrews 2009)
Size classes: macrofossils, mesofossils
