Stratigraphy
Stratigraphy comments: Thus, we assign DNPM-MCT 1496-R to a late Miocene age, even though we do not know with certainty from which side of the Ucayali Unconformity it has come. |
Lithology and environment
Primary lithology: | sandstone |
Secondary lithology: | conglomerate |
Lithology description: Vertebrate fossils from the upper Rio Jurua are typically found in two beds associated with the Ucayali Unconformity (Gaffney et al., 1998, Campbell et al., 2000). They come from late Miocene Red Beds of the Contamana Group that lie below the unconformity (‘‘Huayquerian Beds’’ of Lapparent de Broin et al., 1993), or they come from the Acre Conglomerate unit of the Madre de Dios Formation, which overlies the unconformity (Campbell et al., 1985, 2001). Paleochannels filled with younger sediments that are known to produce vertebrate fossils elsewhere in Acre are apparently not accessible along the upper Rio Jurua´ (Campbell et al., 2000). It is unlikely that this skull is from a younger horizon. The Acre Conglomerate is also considered to be of late Miocene age by Frailey (1986) and Campbell et al. (2001). | |
