The Cretaceous Hengshan Formation at the Baxian tracksite, central Zhejiang
has yielded more than 20 sauropod tracks with a considerable size range
(pes length ranging from 22.7-83.7 cm). The assemblage consists of a more
complete trackway of a large animal, a less complete trackway of a large
animal with a similar orientation and, a small manus-pes set indicating a
smaller trackmaker. Thus, it is a small ichnoassociation with tracks
indicating different-sized trackmakers that moved in different directions.
From a global perspective the assemblage is important, because it is
another data point indicating the presence of different size-classes and
mixed associations with very small and large sauropods, probably
representing juvenile and adult individuals. These tracks are the first
reported from the mid-Cretaceous of this region, being therefore slightly
younger than those already known from Early Cretaceous sites, which are
also attributed to sauropods.
