Abstract [191107-012847] Although fossil footprints are generally recognized by morphological data from autopodia, in some cases they can also be characterized by a sequential deformation of the substrate, since the footprint reaches many sedimentary levels beyond the surface. In such cases, these features are preserved as deformation structures which can be observed in cross-sections, making it difficult to identify their genesis. Thus, they are many times interpreted as load or liquefaction structures related to compaction, tectonism or fluidization, without a direct relationship with the trampling by terrestrial vertebrates and the pressure generated during the contact between a tetrapod autopodium and the substrate, leading to the origin of load structures with successive laminae deformation. The research on the Araripe Basin, Brazil, allowed the discovery of many structures that are related to substrate deformation after dinosaur trampling. This offers a new tool for paleoenvironmental interpretations to this region, as well as it opens new perspectives for understanding ancient terrestrial ecosystems and the origin of deformational structures. Although dinoturbation observed in cross-section is still generally scarcely documented, it enables the understanding of environmental changes from terrigenous to carbonate lake scenarios that are so peculiar in this sedimentary succession. Their regional distribution opens new possibilities to the analysis of the spatial and temporal distribution of dinosaur-trampled structures.

来自巴西北部阿拉里佩盆地阿普蒂安的恐龙践踏，作为古环境解释的工具

摘要 [191107-012847] 虽然化石足迹通常可以通过自足的形态学数据识别，但在某些情况下，它们也可以通过基底的连续变形来表征，因为足迹达到了地表以外的许多沉积层。在这种情况下，这些特征被保留为可以在横截面中观察到的变形结构，因此很难确定它们的成因。因此，它们多次被解释为与压实、构造或流化有关的载荷或液化结构，与陆生脊椎动物的践踏和四足动物自足与基底接触过程中产生的压力没有直接关系，导致连续薄片变形的荷载结构。巴西阿拉里佩盆地研究 允许发现许多与恐龙践踏后基底变形有关的结构。这为该地区的古环境解释提供了一个新工具，并为理解古代陆地生态系统和变形结构的起源开辟了新的视角。尽管在横截面中观察到的双扰动通常仍然很少被记录下来，但它使人们能够了解从陆源到碳酸盐湖情景的环境变化，这些变化在这种沉积序列中非常特殊。它们的区域分布为分析恐龙践踏结构的时空分布开辟了新的可能性。这为该地区的古环境解释提供了一个新工具，并为理解古代陆地生态系统和变形结构的起源开辟了新的视角。尽管在横截面中观察到的双扰动通常仍然很少被记录下来，但它使人们能够了解从陆源到碳酸盐湖情景的环境变化，这些变化在这种沉积序列中是如此独特。它们的区域分布为分析恐龙践踏结构的时空分布开辟了新的可能性。这为该地区的古环境解释提供了一个新工具，并为理解古代陆地生态系统和变形结构的起源开辟了新的视角。尽管在横截面中观察到的双扰动通常仍然很少被记录下来，但它使人们能够了解从陆源到碳酸盐湖情景的环境变化，这些变化在这种沉积序列中是如此独特。它们的区域分布为分析恐龙践踏结构的时空分布开辟了新的可能性。它使人们能够了解从陆源到碳酸盐湖情景的环境变化，这在这个沉积序列中非常特殊。它们的区域分布为分析恐龙践踏结构的时空分布开辟了新的可能性。它使人们能够了解从陆源到碳酸盐湖情景的环境变化，这在这个沉积序列中非常特殊。它们的区域分布为分析恐龙践踏结构的时空分布开辟了新的可能性。
