Ophiuroids from the Middle Triassic (Muschelkalk) of Sadowa Góra, Jaworzno (southern Poland)

Abstract

Ophiuroids belonging to Aspiduriella sp., Aspiduriella similis (Eck), and Arenorbis sp. are described from the Middle Triassic (Muschelkalk) strata of the Sadowa Góra Quarry (Jaworzno) in southern Poland. This is the only Polish location where three taxa of these ophiuroids have been found in one stratigraphic horizon (1st Wellenkalk). To date, only single taxa have been found in the Triassic sections of the eastern part of the Germanic Basin. Finally, other ophiuroid mass aggregations also known from Poland are presented.

Study on restoring abandoned mine lands to economically usable state using the post‐occupancy evaluation method

“…The conducted research confirmed the purposefulness of the revitalization of post‐mining objects in the city of Jaworzno, most often recommending combining many functions, while the protection and access to geological objects revealed during operation and the use of post‐mining objects for recreation and sports has been recommended as the leading direction of transformation (a total of 95.4%). It was found that customer opinions in the form of direct interviews and the results of scientific research carried out in the Sadowa Góra quarry in Jaworzno in the field of geology (Niedźwiedzki et al, 2021; Surmik et al, 2014, 2020) may be an effective object management tool. This is evidenced by the high ratings given by the respondents and the steady increase in the number of visitors.…”

“…Sadowa Góra (Figure 1) quarry is an rea of a lower rank but can be seen as a good example of a space effectively used for public benefit, combining all the most important features of non‐reclaimed post‐mining sites, landscape and educational: fossil remains of vertebrates, echinoderms, brachiopods, etc. (Niedźwiedzki et al, 2021; Surmik et al, 2014, 2020). The quarry is a highly valued tourist attraction because of its scenic qualities, as well as its technical infrastructure elements representing historical value and development elements defining the quality of conditions for use of the facility by end‐users.…”

The quarry is a highly valued tourist attraction because of its scenic qualities, as well as its technical infrastructure and landscape, forms of use, and the influence of these objects on end-users (including the access to communication networks), elements increasing the ease of use of the site, and infrastructure related to education and promotion of Earth sciences were all subjected to quantitative analysis.…”
