Brachiopods have only briefly been discussed or mentioned (e.g. Rak et al. 2012) and trilobites were depicted and described by Chlupáč (1961, 1966) and Rak et al. (2012). The Palaeozoic sequences of the Moravosilesian Basin were exposed to extensive erosion. However, eroded material has been partly preserved in younger sedimentary units, mainly Variscan and Carpathian flysch and molasse sediments. The composition of basal and marginal coarse clastics deposited during the early Badenian transgression in the Carpathian Foredeep reflects the varied provenance of the source material (Brzobohatý & Cicha 1993). Krystek (1974) has recognized 14 types of rock clasts of these clastics between Brno and Prostějov. Dark grey limestone clasts have generally been considered Devonian (e.g. Šob 1940, Krystek 1974), but they have not been studied in detail. In this study, we share information obtained from a limestone boulder, showing that it is of late Tournaisian age, thereby enabling us to contribute to the discussion regarding the provenance of Badenian basal clastics. Brachiopod and trilobite fauna of this boulder proves valuable with respect to our knowledge of the Palaeozoic macrofauna of the Moravosilesian Basin.","PeriodicalId":9332,"journal":{"name":"Bulletin of Geosciences","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42731480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to their abundance and character­ istic morphology, they have been used as index fossils for biostratigraphic zonation schemes in order to define substage­level assemblage zones and even the so­called Toyemia superassemblage zone, slightly exceeding the duration of a stage (Esin & Mashin 1996, Minikh & Minikh 2009). The onset of this superassemblage, cha r ­ acterized by a high degree of endemism, coincides with the disappearance of several generalist fish forms as well as shifts in tetrapod and aquatic invertebrate communities, and has been interpreted in the context of major palaeoenvironmental changes on a regional scale (Bakaev et al. 2017). Toyemia was originally described as a member of Gonatodidae Gardiner, 1967, although similarities with the scanilepiform Evenkia Berg, 1941 have equally been pointed out (Minikh & Minikh 1990). Toyemia is reconstructed as a medium­sized predator of freshwater habitats (Minikh & Minikh 2009, Romano et al. 2016). For a better understanding of the palaeobiology and interrelationships of this both ecologically and strati ­ graphically significant taxon, we are conducting a com­ prehensive morphological study based on new and rediscovered, previously undescribed material.

Most tube-building polychaete worms are benthic and sedentary suspension feeders (e.g. Díaz-Castañeda & Reish 2009). Serpulid-like calcareous tubes displayed a rapid diversification throughout the Jurassic and Cretaceous until the Holocene (Jäger 1983, 2004, 2012, 2014; Ippolitov 2007a, b, 2010; Sklenář et al. 2013; Ippolitov et al. 2014; Kočí & Ledvák 2014; Kočí et al. 2017). They secrete and inhabit a permanent calcareous tube that can be attached to both biogenic and inorganic hard substrates. They are most commonly found as post-mortem encrusters (e.g. Garberoglio & Lazo 2011, Sklenář et al. 2013, El-Sabbagh & El Hedeny 2016, El-Sabbagh et al. 2016, Veselská et al. 2021) but may also be colonizers of living hosts (in vivo; e.g. El Hedeny et al. 2021). Hard substrates in the modern oceans are often heavily encrusted by polychaetes. They are common in all marine settings, ranging from the intertidal down to hadal depths (e.g. Hill 2013, Ippolitov et al. 2014). In addition, they were important encrusting organisms in the geological past (e.g. El-Sabbagh & El Hedeny 2016, El-Sabbagh et al. 2016). Hence, the study of ancient representatives could provide information on palaeoecology and palaeoenvironment. Sediments of the lower‒middle Miocene succession exposed in the Cairo-Suez District yield a significant polychaete assemblage, which, together with bivalves (oysters, pectinids and others), gastropods and echinoids, constitute the characteristic fossil assemblage in that area. Other common fossils include corals and bryozoans. So far, little attention has been paid to fossil calcareous tubedwelling encrusting polychaetes in Egypt (e.g. El-Sabbagh & El Hedeny 2016, El-Sabbagh et al. 2016).

Continental sediments of Aragonian age (end of the early Miocene to middle Miocene; mammal biozones MN4 to MN7/8) are represented in many of these basins (Agustí 2018). While mammal associations have been studied extensively in several palaeontological sites, the malacological record is comparatively poor documented. The few studies carried out on the malacological assemblages recorded in sediments today attributed to an Aragonian age are to some extent outdated (Vilanova y Piera 1859; Royo Gómez 1922, 1926, 1928; Jodot 1959). Also, many of sites and faunas documented in these works could not be precisely located. The available references accurately located and dated correspond to sites attributed to the middle Aragonian of the Tajo Basin (Truc 1977) and the upper Aragonian of the Duero Basin (González Delgado et al. 1986, Civis et al. 1989). The references from the early Aragonian are practically inexistent and correspond to isolated cites or recent multidisciplinary studies in the Ribesalbes-Alcora Basin (Peñalver et al. 2016, ÁlvarezParra et al. 2021). In line with the above, the available data on the mala cological content of the sediments of the Ribesalbes-Alcora Basin (Fig. 1A) are mostly old and very scarce. The first one corresponds to Vilanova y Piera (1859) who studied the materials in the “Balsa de Fanzaraˮ (the classical name for the Cenozoic sediments of the basin) and the nearby area of Alcalá. He cited the generic presence of “lymneasˮ, “planorbis” and “helicesˮ (Vilanova y Piera 1859: p. 44), and more specifically a single specimen of Planorbis rotundatus Brongniart, 1810 from the “Balsa de Fanzara”, which is shown on a plate alongside with four species belonging to the Alcalá area.

Trigonotarbids are usually resolved in the arachnid clade Pantetrapulmonata (e.g. Garwood & Dunlop 2014) as the sister-group of Tetrapulmonata, i.e. the orders Araneae (spiders), Amblypygi (whip spiders), Thelyphonida (whip scorp ions) and Schizomida (schizomids). Trigonotarbids also share characters with the order Ricinulei (hooded tick spiders), such as an opisthosoma with longitudinally divided tergites, a locking mechanism between the prosoma and opisthosoma and a small claw at the tip of the pedipalp (e.g. Dunlop et al. 2009). Trigonotarbid fossils are characterised by a segmented opisthosoma with eight or nine dorsally visible tergites, most of which are, as noted above, divided longitudinally into median and lateral plates. These animals evidently had mouthparts modified for biting in the form of ‘clasp-knife’ chelicerae (Garwood & Dunlop 2010; Haug 2018, 2020) and were presumably predators in Palaeozoic terrestrial ecosystems. Around a hundred species of trigonotarbid have been described in the literature, of which 70 are currently considered valid (Dunlop et al. 2020). Fourteen of them are known from the Czech Republic, and historical descriptions can be found in Stur (1877), Kušta (1883, 1884), Frič (1901, 1904), Petrunkevitch (1953) and Přibyl (1958). More recent summaries and species descriptions can be found in Opluštil (1985, 1986), with a revision of three genera by Dunlop (1995) and the description of a further new species by Hradská & Dunlop (2013).

Increased interest in ichnology resulted in the description and erection of numerous ichnotaxa that allowed for their recurrent recognition and communication. However, after the compilation of the second edition of the Trace Fossils volume in the Treatise of Invertebrate Paleontology (Häntzschel 1975), the number of valid invertebrate ichnogenera has multiplied (Knaust 2012, Buatois et al. 2017). Many ichnotaxa are based on weak grounds, either due to in­ appropriate characteristics chosen as ichnotaxobases, poor preservation, single specimens, or simply overlooked synonymy. Accordingly, comprehensive ichnotaxonomic reciews are necessary for the efficient and robust applic a­ tion of ichnologic evidence. This contribution provides a taxonomic assessment of the ichnospecies Curvolithus gregarius Fritsch, 1908 from the Upper Ordovician of Czechia (see Mikuláš 1992, for previous evaluations of this ichnofauna), based on a reinvestigation of the type material and newly col­ lected specimens. In a general review of the ichnogenus Curvolithus, Buatois et al. (1998) excluded the ichno­ species C. gregarius from that ichnogenus due to the morphological discrepancy with the diagnostic features of Curvolithus. These authors also noted similarities of the type material of C. gregarius with other scratched trace fossils supposedly produced by arthropods, such as Tam bia and Monomorphichnus. However, no formal ichno taxo ­ n omic decision was made at that time, and the ichno­ taxon omic status of this ichno species was left indeterminate. Here, we formally include C. gregarius in Tambia Müller, 1969 as T. gregaria comb. nov. In addition, we briefly revise other ichnotaxa described by Fritsch (1908) that are related to T. gregaria.
