“…The sedimentary rocks that are cut to be used process of industrialization of sedimentary rocks (Fig. 7), where blades are cut to be used as a coating, are generally carriers of fossils, as demonstrated by Francischini et al (2020) and Martill (2001). In many situations, these specimens are crushed for use in the production of cement, agricultural, or industrial inputs, making it impossible to use them for other purposes (Fig.…”

“…Since human prehistory, there has been a relationship between human activities and the discovery of fossils, usually involving residence construction or mineral extraction (Baucon et al 2020;Fernandes 2005;Francischini et al 2020;Zoboli et al 2021). In contrast to archaeology, whose records are contained only in superficial layers, in palaeontology, cases in which the excavation of large volumes of rocks is essential to expose surfaces with fossiliferous content, where the fossils exhibit good preservation conditions, are common.…”

Are Fossils Mineral or Cultural Heritage? The Perspective of Brazilian Legislation

Fossils have great potential for elucidating and popularizing geosciences among all age groups. Brazil, due to its continental dimension and wide geodiversity, has many internationally important fossiliferous sites, which include rocks from the Pre-Cambrian to the Quaternary eras. Thus, in this study, we analyse the legislation and public policies related to the extraction, use, or protection of fossils and palaeontological sites in Brazil. This research examines the legal and infra-legal normative documents and numerous publications on the subject. Our results show that fossils are considered a heritage of the union, i.e. mineral heritage according to the mining code or, exceptionally, cultural heritage when they are related to human culture. Although the sale of fossils as a main product of mineral extraction is not regulated, it is possible and legal to sell material extracted from rocks formed basically by fossils. Hence, it is common to observe the use of such fossiliferous rocks as landfill, construction and paving materials, agricultural inputs, or other types of industrialized products. Mining and civil works, by exposing layers of fresh or slightly weathered rocks and expanding available observation areas, contribute to the advancement of palaeontological knowledge. Accordingly, we evaluate the absence of clear criteria for differentiating whether a fossil is a rare specimen or a common occurrence, entailing the necessity for the proposal of new norms for the preservation of Brazilian fossil heritage. Our study demonstrates that a new legal framework concerning the extraction of mineral resources is crucial to ensure a better preservation of Brazilian fossil heritage and to provide legal certainty for both professionals who research these natural assets and mining companies or those who develop construction projects in sedimentary basins.

“…Firstly, even though the Ouro Ichnosite area has been historically quarried for the exploitation of the Botucatu flagstone Francischini et al, 2020), other quarries occur in further regions of the São Paulo State (Fig. 1; see also Leonardi, 1977), providing flagstones to pave numerous urban areas in the entire state, including at regions where the Botucatu Formation does not crop out (e.g., Leonardi & Carvalho, 2021a).…”

Mammalian lineage is deep rooted in Mesozoic, with several taxa and ichnotaxa described worldwide. One of the most prolific mammaliaform ichnospecies is Brasilichnium elusivum, which is extremely abundant in the Lower Cretaceous Botucatu Formation of the Brazilian Paraná Basin, as well as in other Mesozoic ichnofaunas of North America and Africa. In this contribution, we revisited the proposed southernmost occurrence of B. elusivum using both classical and photogrammetric (3D digitization) approaches. The flagstone containing the studied material was found ex situ, in a sidewalk at Santa Cruz do Sul Municipality (the Rio Grande do Sul State, Brazil), and the results of the performed analysis showed that the tracks cannot be assigned to any ichnotaxon. Lastly, some significant issues related to ichnological research of ex situ track-bearing flagstones and large eolian deposits are discussed. Keywords: Early Cretaceous, Botucatu Formation, mesozoic mammals, South America, vertebrate ichnology.

Walking on Geodiversity: the Artistic Stone-Paved Sidewalks of Lisbon (Portugal) and Their Heritage Value

Sidewalks are not a trivial topic. They are a fundamental element of streets, the main public spaces in urban environments. In modern cities, paving materials are mostly artificial. In Portugal, stone-paved sidewalks are still prevalent and quite characteristic. Walking down a street, you do not need to lift your eyes off the ground to know you are in Portugal. In nineteenth-century Lisbon, a new type of pavement was introduced, the calçada portuguesa , the Portuguese artistic pavement mainly made with white and black limestone or basalt. This pavement is examined herein. More than simply highlighting its geological components, the different meanings and values of the calçada will be discussed from a semiotic perspective. It will also be debated how this geocultural heritage asset became key in shaping the city’s image. How it boosted Lisbon’s memorability, thus generating a strong sense of place among its inhabitants. So much so that these days the calçada patterns are everywhere, from table ware to post stamps, and even on socks. And yet, the long-term survival of the artistic pavement may be in peril. To ensure its preservation, the calçada portuguesa was recently included in the Portuguese Cultural Heritage list, a crucial step towards UNESCO world heritage status. However, in the document ratifying its newly attained status, the geological component of the pavement is mostly neglected. To maximize the conservation effort, the many meanings and heritage values of the calçada , namely the geological ones, should be actively involved, this work hopefully contributing to this end.
