| The camel is buried on top of Unit 2b approximately 2 m to the west of P-3. Mammoth #17, 18 and 22 are approximately 2 m to the right of the photo (to the south). The camel traces laterally to P1-16. (E) P-4 exposed during Phase 2 excavations showing Unit 3c over Unit 2b (note intraclasts derived from Unit 2b), and locations of #17, 18 and #22 bed and #19–21 bed that traces laterally to P1–16. This sedimentological assemblage unconformably overlies Unit 2b as shown in inset photo in a pit dug below the excavation floor. (F) TT-3 exposed from beneath the T2 terrace showing Unit 3b and Unit 3c unconformably over Unit 2a gravels. | ||||||||||

Stratigraphy
| Member: | Unit 3c | ||||
| Stratigraphy comments: The character and timing of events at the WMS and along Owl Creek in central Texas correlate with the interpreted Beaumont and Deweyville formations along the coastal plain of Texas (Blum and Tornquist, 2000). Within this stratigraphic framework, the T3 terrace
and Unit 1 at the WMS and alluvial fans along Owl Creek, correspond with the last interglacial and deposition of the Beaumont Formation during MIS 5 when sea level was higher. |
