Sauropod tracks and trackmakers integrating the ichnological and skeletal records

摘要: espanolLos primeros huesos y pistas de sauropodos o parientes cercanos se encuentran en el principio del Jurasico. Los fueron miembros importantes la fauna dinosaurios durante Jurasico Medio continuaron destacando mayor parte mundo, resto era mesozoica. Resulta dificil identificar los autores las huellas sauropodas debido a que estructura mano pie muchos ellos es similar tambien porque trazas fosiles no suelen conservarse bien. Hay rastrilladas anchas estrechas, pero sabe si esta diferencia rastro reflejo animal. No puede determinar preferian habitat latitud concretos considera distribucion geografica paleoambiental sus huellas. Si combina registro icnologico fosiles, obtienen algunas conclusiones. Cretacico Superior (titanosauridos) son probablemente mas prominentes Hemisferio Sur ornitopodos, mientras ocurre lo contrario Asiamerica. Tanto oseo como icnologico, indican muchas especies con facilidad habitats al menos tienen una estacion seca. Algunos otros, sin embargo, vivieron regiones clima indiscutiblemente humedo. EnglishSkeletal remains of sauropods, as well trackways made by sauropods or their near relatives, first occur in the Early Jurassic. By Middle Jurassic were important members dinosaur faunas, and they continued to be prominent faunas from most world for remainder Mesozoic Era. Identifying makers sauropod footprints is difficult rather uniform construction hand foot often poor preservation trace fossils. Some are wide-gauge, others narrower, but whether this difference trackway pattern reflects structural differences between different trackmakers unknown. The geographic paleoenvironmental occurences tracksites presently inadequate determining latitudinal preferences sauropods. Combined with skeletal record, however, ichnological record does permit some conclusions. Late Cretaceous (titanosaurids) probably more Southern Hemisphere than ornithopods, ornithopods Both suggest that many species common at least seasonally dry habitats. However, lived regions had fairly wet climates.
