Yenangyaung 2, Upper Irrawaddy (Pleistocene of Myanmar)

Also known as AMNH A2

Where: Myanmar (20.4° N, 94.9° E: paleocoordinates 19.4° N, 94.9° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Upper Member (Irrawaddy Formation), Early/Lower Pleistocene (2.6 - 0.8 Ma)

• lower Pleistocene, Yenangyaung fossil beds. 4000 ft above base

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; ferruginous, argillaceous, carbonaceous sandstone

• coarse, current bedded sands, at the base there is usually a well-marked "red bed" or old lateritic land surface. Associated with this band either above ir or below, there is frequently a bed of white sand rich in kaolin. Interbedded bands or even beds of some thickness of a clay, which approaches pipe-clay in general characters, are frequent in the lower beds and again in the higher part of the Irrawadian. The Irrawadian is famous for the enormous quanitity of silicified fossil wood which it contains...The series has also yielded a number of interesting vertebrate remains

Size class: macrofossils

Preservation: replaced with silica

Reposited in the AMNH
