“…Bakker (1968Bakker ( , 1986Bakker ( , 1997 interpreted the scenario as evidence of an advanced social organisation that included parental care with older animals apparently encircling and protecting the smaller and presumably more vulnerable young. This viewpoint was revised by other investigators in that the animals were simply travelling in a 'staggered or spearhead formation' with the larger and presumably faster members progressing ahead of the smaller (Lockley et al 1986). There are numerous similar tracksites in North America including the Purgatoire River site in southeastern Colorado, where more than 100 trackways are preserved, apparently left by the sauropod herds that once travelled across the mudflats along the perimeter of inland seaways (Lockley 1986b(Lockley , 1991Lockley et al 1986), and further tracks can be found at the Hidden Canyon locale in Utah (Barnes and Lockley 1994).…”

“…A bimodal orientation pattern has often been associated with physical restrictions, i.e. natural barriers such as shorelines, river-banks, patches of dense vegetation (Lockley et al, 1986;Thulborn, 1990;Lockley, 1991), or even palaeogeographical constraints on a more regional scale (Moratalla and Hernán, 2010). A multidirectional or randomly distributed orientation pattern, on the other hand, may suggest individual movement.…”

“…Among the sauropod ichnotypes in the global track record (Fig. 5.1), gregarious behaviour has only been described in association with Parabrontopodus-like/Breviparopus-like and Brontopoduslike ichnotypes (Lockley et al, 1986;1994b;2002a;2002b;Lockley and Meyer, 2000;Mezga et al, 2007;Marty, 2008) or among other sauropods not yet associated with a specific ichnotype (Leonardi, 1994;Day et al, 2004). …”

“…In Europe, gregarious behaviour in dinosaurs has been inferred on the basis of ichnological evidence for different dinosaur groups; these include theropods, ornithopods and sauropods (e.g., Lockley et al, 1994a;Pérez-Lorente et al, 1997;Lockley and Meyer, 2000;Day et al, 2004;Barco et al, 2006;Mezga et al, 2007;García-Ortíz de Landaluce and Díaz-Martínez, 2008;Marty, 2008;Castanera et al, 2011). On a worldwide scale, parallel sauropod trackways with regular intertrackway spacing have been interpreted as a "herd", "gregarious behaviour", "gregariousness", or simply "social behaviour" (Ostrom, 1972;Lockley et al, 1986;Lockley, 1991;Lockley et al, 2002a;2002b;Myers and Fiorillo, 2009), implying that the individuals were moving together simultaneously.…”

More than a hundred sauropod tracksites, ranging in age from Middle Jurassic (Bathonian) to Late Cretaceous (Maastrichtian), are reported from the Iberian Peninsula (Spain and Portugal). Sauropod trackway orientation patterns throughout an entire geographic area such as the Iberian Peninsula and over different time periods may provide new data about the palaeoecology and behavioural patterns of sauropods. The studied tracksites exhibit two main trackway orientation patterns, directional and random, indicating different behaviours in gregarious or solitary (milling) individuals. Gregarious behavioural patterns are mainly observed within Parabrontopodus/Breviparopus-like and Brontopodus-like ichnotypes of a single size class (either small or medium-sized), indicating age segregation. Among the gregarious sauropods the former ichnotype is linked with inland environments, while the latter is mainly linked with coastal environments. Solitary trackways are mainly of medium-sized to large individuals, are also linked with both inland (Parabrontopodus/Breviparopus-like) and coastal environments (Parabrontopodus/Breviparopus-like, Brontopodus-like), and belong to the above-mentioned ichnotypes as well as to Polyonyx-like ichnotypes. Thus, no obvious link between gregarious behaviour and the palaeoenvironmental setting can be inferred from the sauropod track record of the Iberian Peninsula. Nonetheless, sauropod trackways showing titanosauriform characters (Brontopoduslike) are more common in coastal environments, contrary to what might be expected given this group's apparent taxonomic preference for inland environments.Keywords: Sauropod trackways, palaeoecology, gregarious behaviour, Jurassic, Cretaceous, Iberian Peninsula Resumen El registro Ibérico (España y Portugal) de icnitas de saurópodos está representado por más de cien yacimientos cuya edad varía desde el Jurásico Medio (Batoniense) al Cretácico Superior (Maastrichtiense). El estudio de la orientación de los rastros, en un área determinada como la Península Ibérica y en diferentes edades, nos ha permitido obtener nuevos datos sobre el comportamiento de los saurópodos. Los rastros de los yacimientos estudiados presentan dos patrones de movimiento distintos, direccionales y aleatorios, que reflejan distintos comportamientos en individuos gregarios o solitarios (deambulantes). El patrón que indica comportamiento gregario se observa en los icnotipos "Parabrontopodus/Breviparopus-like" y "Brontopodus-like" en saurópodos del mismo tamaño (pequeño o medio), lo que indica segregación por edad. El primer icnotipo se ha conservado en sedimentos depositados en ambientes terrestres mientras que el segundo lo hace fundamentalmente en ambientes costeros. Los rastros solitarios son, en su mayoría, de saurópodos de tamaño medio o grande, conservados tanto en medios terrestres ("Parabrontopodus/Breviparopus-like"), como costeros ("Parabrontopodus/Breviparopus-like" y "Brontopodus-like") y pertenecen a los dos icnotipos mencionados anteriormente y a un tercero: "Polyonyx...
