Also known as Confuciusornis sanctus type; Beipiao
Where: Liaoning, China (41.6° N, 121.0° E)
• Paleocoordinates: 41.5° N, 129.6° E (Wright 2013)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Yixian Formation (Jehol Group), Late/Upper Barremian to Late/Upper Barremian (130.0 - 122.5 Ma)
• thought to be Tithonian or possibly "as young as middle Cretaceous" by Hou et al. 1995, but Yixian localities in general are now thought to be Barremian or early Aptian
• bed-level stratigraphic resolution
Environment/lithology: lacustrine; lithified mudstone
•
•As a result, tuffs are commonly interbedded with the shales or mudstones of these formations, and even the normal lake sedimentation contains tuffaceous components (Figure 1). The Yixian Formation mainly comprises basalts with interbedded siliciclastic sediments, and can be divided into several beds (Zhongue, 2006).
Size class: macrofossils
Preservation: adpression, soft parts
Reposited in the IVPP
• type specimen of C. sanctus donated by an amateur fossil collector, Zhang He" and second specimen "from the same locality" found "by a farmer, Yang Yushan; this is not the most productive, second Confuciusornis locality, which is at Sihetun (Zhou and Hou 2002)
