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. | Muhoroni Agglomerates are volcanic deposits near a vent above base level. Contemporary channel filled with unbedded partly calcified 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..."
