Jiliniornis huadianensis was collected from the Middle Eocene Huadian Formation in the Jilin Province, China. Because the age of the Middle Eocene Huadian Formation is not precisely known a conservative approach was taken regarding the choice of the age prior on the node representing the split between Charadrii and the rest of the charadriiform crown clade. Although the holotype of Jiliniornis huadianensis may be older than latest Middle Eocene, an age of 41.3 Ma, corresponding to the uppermost Middle Eocene boundary (Lutetian-Bartonian boundary) is suggested as a qualitative prior on the split between Charadrii and the rest of crown Charadriiformes.

The systematic position of Jiliniornis huadianensis was evaluated by Smith (2011a) in a combined analysis of morphological and molecular sequence data (Figure 1). Not surprisingly, given that it could only be scored for 26 of 365 characters, Jiliniornis huadianensis was placed in a polytomy near the base of Charadriiformes along with Scolopaci and Charadrii species in the strict consensus cladogram resulting from the analysis of that taxon and extant charadriiform species (Smith, 2011a, figure 8.7). No alternative hypothesis has been proposed linking this specimen to any clade other than Charadrii.
