The present 3D dataset contains the 3D models analyzed in Xing et al. (in press), Newly discovered Cretaceous dinosaur track sites from the Jiaguan Formation, Sichuan Province, China: ichnotaxonomy and preservation. The dataset includes photogrammetric 3D models of the specimens shown in Figures 6–9 and 16–17 of the original article. These correspond to track-bearing slabs and selected footprints from the Hongyangoukou and Jinyuxi tracksites and the Shimiaogou 2025 tracksite in the Gulin area, Sichuan Province, China. The Hongyangoukou material comprises three reddish-brown siltstone slabs preserving at least 61 theropod tracks, including nine trackways (HYGK-T1 to HYGK-T9) and isolated footprints (HYGK-TI1 onward). The Jinyuxi material comprises one isolated theropod natural cast (JYX-TI5) assigned to cf. Eubrontes, associated with microbially induced sedimentary structures (MISS). The Shimiaogou 2025 material comprises two slabs preserving at least 25 dinosaur footprints, including ornithopod trackways SMG25-O1 and SMG25-O2, theropod trackway SMG25-T1, and isolated footprints; all occur as natural positive reliefs. The 3D surface models are provided in PLY format.
