| contents | FIGURE 9. Palaeoecological interpretations of tracksites. A, Part of the Mill Canyon tracksite, Utah, US (Upper Jurassic; Cedar Mountain Formation), showing small and large theropod tracks and a manus-only sauropod trackway (direction of travel to the right). This site shows a particularly diverse trace fossil assemblage, including tracks of ornithopods, different types of theropods, sauropods, and possible crocodylomorphs (Lockley et al., 2014). Also note the warty surface texture, which resulted from the growth of a microbial mat (Pustularichnus; Simpson et al., 2022). The view shown is ca. 2.2 m in width. B, The main section of the El Contadero tracksite, La Rioja, Spain (Lower Cretaceous, Enciso Group). The preserved ornithopod tracks vary from being deep with pronounced displacement rims to shallow with low displacement rims. This variation could be explained by spatial differences in substrate properties, in which case they could have been left by a single group (Pérez-Lorente, 2015). Alternatively, the tracksite could be time-averaged, with the shallow tracks formed when the substrate was firm, and the deeper tracks formed when it was soft. |
