摘要：

The Kokorkom desert extended over an area of 826 km(2) in the central-west sector of Neuquen and Rio Negro provinces along the area of the backbulge basin within the Andean Foreland basin in the Neuquen Basin. Its deposits constitute the middle-upper section of the Candeleros Formation (Cenomanian) and reach approximately 130 m thick. Tracks are found on wet and dry interdune and within draa slipface deposits. They constitute biogenic deformation structures characterized by folded-up and/or brecciated sandstone levels formed under dry and/or wet substrate conditions with passive filling. The degree of preservation varies, but the identification of digit impression suggests that they were produced by theropods or iguanodontians. (C) 2017 Elsevier Ltd. All rights reserved.
