A new paper by Chen et al. (2013) illustrates new early Late Cretaceous pterosaur tracks (Fig. 1). The manus print was outlined before publication.
The new tracks are notable.
The pes is narrow and digits 2-4 are aligned transversely. The manus impression is relatively large with wide angles between the fingers.
Pteraichnus dongyangensis Holotype: Manus: DYM-04666-1; Pes: DYM 04666-3. The diagnosis of the manus print is based on the finger angles. The pes is based on a width to length ratio of 17 percent. Chen et al. (2013) note the pes print is 9 cm long, but that includes the toe drag marks.
It’s good to have a catalog of pterosaur pedes (Peters 2011) to compare tracks to. Here Chaoyangopterus appears to be a great match, even down to the scale bars and chronology!
Chaoyangopterus is a pre-azhdarchid pterosaur with relatively small and narrow plantigrade feet. Seems to be a good match in nearly every aspect.
