Abstract
We report here on the first tetrapod tracks from the Triassic of the Nurra region (north-western Sardinia, Italy). The specimens were found on sandstone blocks used to build a fence limiting a seasonal camping, in the coastal area north of Capo Caccia promontory. Lithologic and petrographic features allowed an assignment of the track-bearing blocks to the middle-upper portion of the Anisian (Middle Triassic) Arenarie di Cala Viola (Buntsandstein). Footprints are attributed to the ichnotaxa Rhynchosauroides and Rotodactylus, two common ichnotaxa of late Early Triassic and Middle Triassic ichnofaunas of Europe and United States, commonly referred in the literature to neodiapsid and archosaur producers, respectively.
我们在这里报告了来自Nurra地区(意大利撒丁岛西北部)三叠纪的第一批四足动物足迹。这些标本是在卡波卡西亚角北部沿海地区用来建造季节性露营围栏的砂岩块上发现的。岩性和岩石学特征表明，这些带径迹的块体属于Anisian(中三叠统)Arenarie di Cala Viola (Buntsandstein)的中上段。足迹归属于早三叠世晚期和中三叠世欧美地区常见的两个鱼类群——Rhynchosauroides和Rotodactylus，文献中通常分别将其称为新鲤科动物和祖龙的生产者。
期刊介绍：
The Italian Journal of Geosciences (born from the merging of the Bollettino della Società Geologica Italiana and the Bollettino del Servizio Geologico d''Italia) provides an international outlet for the publication of high-quality original research contributions in the broad field of the geosciences.
It publishes research papers, special short papers, review papers, discussion-and-replies for their rapid distribution to the international geosciences community.
The journal is firstly intended to call attention to the Italian territory and the adjacent areas for the exceptional role they play in the understanding of geological processes, in the development of modern geology and the Earth sciences in general.
The main focus of the journal is on the geology of Italy and the surrounding sedimentary basins and landmasses, and on their relationships with the Mediterranean geology and geodynamics. Nevertheless, manuscripts on process-oriented and regional studies concerning any other area of the World are also considered for publication.
Papers on structural geology, stratigraphy, sedimentology, basin analysis, paleontology, ecosystems, paleoceanography, paleoclimatology, planetary sciences, geomorphology, volcanology, mineralogy, geochemistry, petrology, geophysics, geodynamics, hydrogeology, geohazards, marine and engineering geology, modelling of geological process, history of geology, the conservation of the geological heritage, and all related applied sciences are welcome.
