“…This is very likely because of the simplicity associated with the ease of point-and-shoot camera operations as the basic means of data collection. As a consequence this approach has been used for track data collection (Thulborn, 1997; Matthews & Breithaupt, 2001; Breithaupt, Matthews & Noble, 2004; Matthews, Noble & Breithaupt, 2006) and documentation (Bates et al, 2008; Petti et al, 2008; Romilio & Salisbury, 2014; Pond et al, 2014; Salisbury et al, 2014), ichnotaxonomic assessments (Pond et al, 2014; Lallensack, Van Heteren & Wings, 2016; Salisbury et al, in press), and for demonstrating track sequence formation (Xing et al, 2015). …”

“…The traditional technique of documenting dinosaurian tracks and tracksites has been largely restricted to acquiring data in two dimensions. While useful for determining measurements for pace and stride, the approach provides only limited morphological information for detailed comparative work (Xing et al, 2015: Fig. 6).…”

The abundant dinosaurian tracksites of the Lower Cretaceous (Valanginian–Barremian) Broome Sandstone of the Dampier Peninsula, Western Australia, form an important part of the West Kimberley National Heritage Place. Previous attempts to document these tracksites using traditional mapping techniques (e.g., surface overlays, transects and gridlines combined with conventional photography) have been hindered by the non-trivial challenges associated with working in this area, including, but not limited to: (1) the remoteness of many of the tracksites; (2) the occurrence of the majority of the tracksites in the intertidal zone; (3) the size and complexity of many of the tracksites, with some extending over several square kilometres. Using the historically significant and well-known dinosaurian tracksites at Minyirr (Gantheaume Point), we show how these issues can be overcome through the use of an integrated array of remote sensing tools. A combination of high-resolution aerial photography with both manned and unmanned aircraft, airborne and handheld high-resolution lidar imaging and handheld photography enabled the collection of large amounts of digital data from which 3D models of the tracksites at varying resolutions were constructed. The acquired data encompasses a very broad scale, from the sub-millimetre level that details individual tracks, to the multiple-kilometre level, which encompasses discontinuous tracksite exposures and large swathes of coastline. The former are useful for detailed ichnological work, while the latter are being employed to better understand the stratigraphic and temporal relationship between tracksites in a broader geological and palaeoecological context. These approaches and the data they can generate now provide a means through which digital conservation and temporal monitoring of the Dampier Peninsula’s dinosaurian tracksites can occur. As plans for the on-going management of the tracks in this area progress, analysis of the 3D data and 3D visualization will also likely provide an important means through which the broader public can experience these spectacular National Heritage listed landscapes.

About 350 dinosaur footprints, including the longest dinosaur trackway currently on record in Africa, are preserved in the Lower Jurassic Etjo Formation at the Otjihaenamaparero 92 Farm in north-central Namibia. This historically significant locality was among the first dinosaur tracksites ever to be reported from the African continent and is today a National Monument and tourist destination. Nevertheless, its ichnofauna was never described in any detail. Herein we discuss its significance for southern African palaeontology. Although originally described in the 1920ies as new ichnotaxa and later compared to other ichnotaxa described from Lesotho, most tracks of the Namibian Etjo Formation are referable to the classic North American ichnogenera Eubrontes, Anchisauripus and Grallator. A single median-sized theropod trackway is cautiously assigned to Kayentapus, but shows characters that differ from North American and European Kayentapus, linking it to other "Kayentapus-like" tracks from Lesotho and Madagascar. A small-sized functionally tridactyl morphotype with posteriorly directed hallux, common at Otjihaenamaparero, appears to represent a genuinely African form that may also occur in Lesotho. This ichnofauna strengthens the assignment of an Early Jurassic age to the Etjo Formation and opens a window on the diversity of dinosaur communities in arid environments of Early Jurassic southern Gondwana.
