| Lithology description: Lens of calcareous mudstone (a lens of calcareous mudstone (with minimum dimensions of 80 cm length, 50 cm width and 20 cm depth) composed of thousands of morphologically homogenous eggshell fragments associated with a number of near-complete eggs (n=7), complete and identifiable bird bones (n=12) and numerous indeterminate bone fragments (n∼50) | |
| Environment: | pond |
| Geology comments: A very short transport distance from a river bank or sandbar into a small, shallow pond trapped by rising water. A seasonal, tropical monsoonal climate with long dry periods followed by short, wet bursts has been inferred. Periodic floods, sometimes extreme, have also been demonstrated based on sedimentological evidence. | |
