3D meshes of H1 and H6 footprints at PK23 track site, Northern Chile

We report new ichnites corresponding to a trackway composed of three tetradactyl pedal footprints and plant remains near Southeastern Guatacondo, Tarapacá Region, within the transition of Majala and Chacarilla Formations (Late Jurassic-Early Cretaceous). The fossils were found in the context of a Copper Mining road construction at the PK23 site, Quebrada Blanca Phase 2 project, by the Teck Mining Company Quebrada Blanca S.A.
We performed stratigraphical, paleobotanical, and paleoichnological studies, along with the footprint characterization and comparisons by Principal Component Analysis, and Discriminant Analysis of I-II, II-III and III-IV interdigital angles, using a large tetradactyl footprint morphological database of potential producers (dinosaurs, crocodiles, lepidosaurs, and pterosaurs). Additionally, we performed 3D pedal computer modeling kinematic analysis of the Chilesaurus diegosuarezi’s 3D tetradactyl foot under two different sedimentary conditions (i.e. hard soil with sup..., This investigation was carried out in transitional strata between the Majala and the Chacarilla formations outcropping eight kilometers to the southeast of Guatacondo, Tarapacá Región in northern Chile, within the Quebrada Blanca Phase 2 project owned by Teck Mining Company Quebrada Blanca S.A (Fig. 1). Unfortunately, it is no longer possible to see the footprints in-situ, since the original site subsequently collapsed, so. However, prior to this event, we carried out three field trips in which it was possible to scan some sectors of the surface in 3D (Available from DRYAD WEBSITE), along with a collection of casts and rock samples. 
Six biogenic structures were initially recognized, in which three correspond to a single trackway. Two of them (H1-H6, virtual meshes available at the DRYAD WEBSITE), show good preservation of anatomical details. These footprints were scanned using Go!Scan20 for the generation of 3D models with the software Vxelements, CreaformMR.

Data contains two untextured meshes for H1 and H6 footprints in obj format. Files have been set for easy printing, including a straight base which facilitates exhibition on a table. The original dimensions have not been modified.

## Description of the data and file structure

Data could be used for education and/or for comparison with other footprints.
