KB3, Kossom Bougoudi (Miocene to of Chad)

Also known as KB03

Where: Chad (16.3° N, 18.7° E)

• Paleocoordinates: 14.2° N, 19.0° E (Wright 2013)

• coordinate stated in text

• local area-level geographic resolution

When: Late/Upper Miocene to Late/Upper Miocene (11.6 - 3.6 Ma)

• fossils are shown spanning most of a 5 m section

• member-level stratigraphic resolution

Environment/lithology: lacustrine; unlithified, bioturbated, green sandstone

• lithology represents "repetitive climatic fluctuations between environments of ephemeral streams and of lakes"
• "The sandstones are little or poorly cemented, without oblique stratification but strongly channeled... markedly heterogranular with an abundant supporting matrix. Frequent dessication cracks... insect bioturbations... are omnipresent... Fossils are known almost entirely from lower and upper green sandstones"

Size classes: macrofossils, mesofossils

Collection methods: "focus of this paper is on the environment and faunas"
