The city of Araraquara in southeastern Brazil is unique regarding its paleontological record. Flagstones have been quarried from eolianites (Botucatu Formation, Lower Cretaceous) since the beginning of the twentieth century and used to pave and cover public and private spaces of the city. As a consequence, fossil tracks and traces (ichnofossils) of invertebrates, early mammals, and dinosaurs are widely distributed in the flagstones that pave the sidewalks of the city, right under the feet of Araraquara’s inhabitants. In this paper we aimed to characterize this unique fossil record, focusing on the main trace morphotypes and their conservation. In a survey conducted in 2007–2008, 585 trace fossil-bearing flagstones were identified across Araraquara, much of which are moderately to poorly preserved. Nevertheless, optimally preserved (elite) traces of very high scientific potential were also recorded. The present study also includes a history of investigations conducted regarding these materials and discusses different aspects, difficulties, and peculiarities of conservation efforts towards this urban paleontological heritage, including some recently achieved goals.

Araraquara人行道的技术记录：历史，保护和巴西东南部城市古生物学遗产的观点

巴西东南部的Araraquara市就其古生物学记录而言是独一无二的。自20世纪初以来，石板石是从风成岩（白垩统下的Botucatu地层）中采集的，用来铺路和覆盖城市的公共和私人空间。结果，无脊椎动物，早期哺乳动物和恐龙的化石痕迹（化石化石）被广泛分布在石板路上，这些石板在阿拉拉夸拉居民的脚下铺着城市的人行道。在本文中，我们旨在表征这一独特的化石记录，着重于主要痕迹形态型及其保护。在2007年至2008年进行的一项调查中，在Araraquara发现了585片含化石的石板，其中许多是中度至不良保存。不过，还记录了具有极高科学潜力的最佳保存（精英）痕迹。本研究还包括对这些材料进行调查的历史，并讨论了针对这种城市古生物学遗产的保护工作的不同方面，困难和特殊之处，包括最近达成的一些目标。
