“…The variation in some parameters due to changes in direction or sinuous trajectories of travel has also been described in other sauropod trackways (Casanovas et al. 1997; Calvo & Mazzetta 2004; González Riga & Calvo 2009; Ishigaki & Matsumoto 2009). Other turning sauropod trackways have been reported, but in these cases the variations in parameters were not described in detail (Meyer 1993; Meyer et al.…”

“…(1997) and two sauropod trackways from Argentina with sinuous trajectories (Calvo & Mazzetta 2004; González Riga & Calvo 2009) have also been classified as wide‐gauge. The absence of accurate data for the new parameters (PTR or WAP/PL) in all of these trackways makes it impossible to establish whether they are intermediate or wide (except in the case of the latter Argentinean trackway, which is truly wide, González Riga & Calvo 2009). Whatever the case, the drawings in the original articles show no strong evidence of a narrower part at the turning points or in the sinuous parts.…”

J., 2012: Ethological variations in gauge in sauropod trackways from the Berriasian of Spain. Lethaia, Vol. 45, Two sauropod trackways from the Early Cretaceous (Berriasian) of the Cameros Basin (Spain) show important variations in trackway gauge, along the same trackway. These variations seem to be associated with different behaviours; on the one hand with a significant variation in the direction of travel (turning phenomena) and on the other hand with a decrease in speed, probably associated with the properties of the substrate. These variations in sauropod trackways provide the trackway gauge debate with new data, supporting the hypothesis that the walking style and substrate properties may in some cases determine this sauropod character. The study of turning sauropod trackways improves our knowledge of sauropod locomotion.

“…Additionally, an osteological pes of a given length may produce tracks of varying lengths that marginally exceed this 'base' osteological length, depending on numerous factors too difficult to quantify simplistically (e.g., behavior, substrate, soft tissues). This is corroborated by the typical variation in pedal track lengths in well-preserved sauropod trackways (e.g., Farlow et al, 1989;Gonz alez Riga and Calvo, 2009;Xing et al, 2015f), which would in turn produce a variety of reverse-extrapolated hip height estimates if using a uniform hip height to track length ratio.…”

Extensive and well-preserved tracksites in the coastally exposed Lower Cretaceous (Valanginian-Barremian) Broome Sandstone of the Dampier Peninsula provide almost the entire fossil record of dinosaurs from the western half of the Australian continent. Tracks near the town of Broome were described in the late 1960s as Megalosauropus broomensis and attributed to a medium-sized theropod trackmaker. Brief reports in the early 1990s suggested the occurrence of at least another nine types of tracks, referable to theropod, sauropod, ornithopod, and thyreophoran trackmakers, at scattered tracksites spread over more than 80 km of coastline north of Broome, potentially representing one of the world's most diverse dinosaurian ichnofaunas. More recently, it has been proposed that this number could be as high as 16 and that the sites are spread over more than 200 km. However, the only substantial research that has been published on these more recent discoveries is a preliminary study of the sauropod tracks and an account of the ways in which the heavy passage of sauropod trackmakers may have shaped the Dampier Peninsula's Early Cretaceous landscape. With the other types of dinosaurian tracks in the Broome Sandstone remaining undescribed, and the full extent and nature of the Dampier Peninsula's dinosaurian tracksites yet to be adequately addressed, the overall scientific significance of the ichnofauna has remained enigmatic.At the request of the area's Goolarabooloo Traditional Custodians, 400C hours of ichnological survey work was undertaken from 2011 to 2016 on the 25 km stretch of coastline in the Yanijarri-Lurujarri section of the Dampier Peninsula, inclusive of the coastline at Walmadany (James Price Point). Forty-eight discrete dinosaurian tracksites were identified in this area, and thousands of tracks were examined and measured in situ and using three-dimensional photogrammetry. Tracksites were concentrated in three main areas along the coast: Yanijarri in the north, Walmadany in the middle, and Kardilakan-Jajal Buru in the south. Lithofacies analysis revealed 16 repeated facies types that occurred in three distinctive lithofacies associations, indicative of an environmental transgression between the distal fluvial to deltaic portions of a large braid plain, with migrating sand bodies and periodic sheet floods. The main dinosaurian track-bearing horizons seem to have been generated between periodic sheet floods that blanketed the preexisting sand bodies within the braid plain portion of a tidally influenced delta, with much of the original, gently undulating topography now preserved over large expanses of the present day intertidal reef system. Of the tracks examined, 150 could be identified and are assignable to a least eleven and possibly as many as 21 different track types: five different types of theropod tracks, at least six types of sauropod tracks, four types of ornithopod tracks, and six types of thyreophoran tracks. Eleven of these track types can formally be assigned or compared to existing or new ichnotaxa,...

“…Titanopodus mendozensis presents manus tracks (mean length and width of 19.6 cm and 32.2 cm, respectively) without claw imprints, rotated outward (25-48º), with asymmetrical crescent shape and acuminate external edge, and subtriangular to subcircular pes tracks, longer than wide (mean length and width of 46 cm and 42.4 cm, respectively) and rotated outward. T. mendozensis presents a heteropody of 1:3 and is a wide-gauge trackway, with a mean PTR of 29% (González Riga and Calvo, 2009).…”

A new narrow-gauge sauropod trackway from the Cenomanian Candeleros Formation, northern Patagonia, Argentina

Dinosaurs are extremely abundant in the Upper Cretaceous Neuquén Group of the Neuquén Basin (Argentina). Nevertheless, while osteological remains are rich the ichnological record is more restricted. A new sauropod dinosaur trackway with five manus-pes imprint sets discovered in the Cenomanian Candeleros Formation is described here. The trackway belongs to the narrow-gauge type that is identified for the first time in the Cenomanian and possibly for the Late Cretaceous. It is preserved as concave epirelief in fine-grained sandstones from floodplain deposits. The tracks, which are large in size (average length of 98 cm), include conspicuous rims with very well-preserved symmetrical ripples on top that are documented for the first time in the track record. Due to their preservation and the absence of clear anatomical details, the trackway was not assigned to any particular ichnotaxon. Taking into account the presence of rebbachisaurid diplodocoid remains in the Candeleros Formation, the classical association of narrow-gauge trackways with diplodocoids and the inferred gleno-acetabular distance, it is suggested that the studied trackway might belong to a large-sized rebbachisaurid. The worldwide record of Cenomanian dinosaur tracks includes only a few records of sauropod tracks. Thus, this new
