southwest of Beipiao City (Cretaceous to of China)

Also known as Liaoningornis type

Where: Liaoning, China (41.8° N, 120.8° E: paleocoordinates 44.5° N, 122.6° E)

• coordinate based on nearby landmark

When: Lujiatun Member (Yixian Formation), Late/Upper Barremian to Late/Upper Barremian (130.0 - 122.5 Ma)

• "Bottom of Yixian Formation [i.e., Member]; Tithonian" based on author's views about the age of the Yixian Formation (unit is Barremian - Aptian according to later authors)

• bed-level stratigraphic resolution

Environment/lithology: lacustrine - small; lithified siliciclastic sediments

• 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

Reposited in the IVPP

• collected after the publication of two papers on Confuciusornis in 1995
