Where: Hebei, China (41.9° N, 116.6° E: paleocoordinates 43.0° N, 118.8° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Qiaotou Formation (Jehol Group), Late/Upper Jurassic to Late/Upper Jurassic (161.5 - 125.0 Ma)
• "Qiaotou Formation, Late Jurassic-Early Cretaceous"
•"stratigraphically lower than the Yixian Formation... The exact age of [the Qiaotou Formation] is currently under study"
Environment/lithology: terrestrial; lithified sandstone
•
•The structural patterns in Domain III2 appear to be associated with the lithology of the deformed sedimentary rocks. Two thick, weaker stratigraphic segments, e.g., the slate or shale of first member of the Qiaotou Formation and the Changlingzi Formation, have very different structural patterns from those developed in the well-bedded sandstone of the 2nd, 3rd, 4th, and 5th Members of the Qiaotou Formation (Yang et. al, 2011).
