These vast regions, currently represented by central southern Europe and North Africa, experienced a major environmental change during the Late Ordovician with the abrupt appearance of calcareous deposits of highly variable thickness (e.g. Villas et al. 2002, Boucot et al. 2003). The limestone deposition was associated either with a sharp climatic global warming named as Boda Event after the Boda Limestone of Sweden (Fortey & Cocks 2005), or with a general cooling (Cherns & Wheeley 2007). Currently, the Late Ordovician (Katian–Hirnantian) through earliest Silurian (Rhuddanian) time interval is regarded as a period of variable climate and sea level conditions, with at least two separate pulses of glacial advance and one of retreat during a late Katian global warm interval (Melchin et al. 2013, Ghienne et al. 2014, Kröger et al. 2017). The latter cooling triggered widespread marine anoxia by reorganisation of the thermohaline circulation, which resulted in the second pulse of the Hirnantian mass extinction, the first of the ‘Big Five’ Phanerozoic mass extinctions (Bartlett et al. 2018). The pioneer study by Fuganti & Serpagli (1968) on the Katian fauna of the Urbana Limestone of the Central Iberian Cordillera started the Ordovician conodont stud ies in the Iberian Peninsula (Fig. 1). Since then, several conodont studies have focused on the Upper Ordovician limestones present in the different tectonometamorphic domains of Spain (summarised by Sarmiento et al. 2011). Particularly, the common record of conodonts of the Amorphognathus ordovicicus Zone (Ka3–4 time slices of Bergström et al. 2009) has allowed correlation of the the Urbana Limestone with the Cystoid Limestone in the Eastern Iberian Cordillera, the ʻPelmatozoan Lime­ stoneʼ in the Ossa­Morena Zone, the ʻunidad calcárea superiorʼ in the Cantabrian Zone, the Estana Formation in the Pyrenees, and the Ferradosa Formation from the Portuguese Central Iberian Zone (e.g. Hafenrichter 1979; Sarmiento 1990, 1993, 2002; Sarmiento et al. 2001; del Moral 2003, 2007; del Moral & Sarmiento 2008).","PeriodicalId":9332,"journal":{"name":"Bulletin of Geosciences","volume":"1 1","pages":"455-478"},"PeriodicalIF":1.9,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49342147","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}

Among the early representatives of the suborder Belemnopseina Jeletzky, 1965, belemnites possessing long ventral and short dorsal alveolar grooves on the rostrum, i.e. members of the Tethyan family Dicoelitidae Sachs & Nalnjaeva, 1967, are the least studied group, especially in the MediterraneanCaucasian Tethys (western Tethys).

Part of this success has been attributed to one evolutionary “strategy”: the stem species of Euarthropoda had a body with numerous segments, each of these segments bearing a pair of appendages, all of these subsimilar (e.g. Maas & Waloszek 2001; Haug J.T. et al. 2013, fig. 2.3.b, and references therein). Different lineages of Euarthropoda varied this ancestrally uniform body. Several adjacent segments were modified in groups, forming then functional units for specific needs. Such functional units, tagmata, may perform sensory functions, locomotion, feeding, respiration or other tasks. With this background we should expect that tagmosis, the subdivision of the body into several functional units, evolves within the different lineages of Euarthropoda, leading to very different patterns of body organisation between the different lineages as well as within one lineage (partly this morphological diversity or disparity appears to be a result of developmental plasticity, see e.g. Moczek 2010, Moczek et al. 2011, Minelli 2016 and references therein). Yet, in many lineages the pattern appears to be fixed already quite early within a lineage. For example, Euchelicerata, the group including spiders, scorpions and all their relatives, is generally thought to have a stereotypic tagmosis pattern. The ocular segment and post-ocular segments 1–6 are supposed to form the so-called prosoma; post-ocular segments 7–19 supposedly form the opisthosoma (see Dunlop & Lamsdell 2017 for a recent discussion). However, when looking closely at many eucheliceratan ingroups this is not quite that obvious or at least not as simple as often stated (see e.g. discussion in Haug C. et al. 2012a). Here we want to consider the evolution of the tagmosis in modern scorpions. Generally, modern scorpions have been considered to be organised into three tagmata: the prosoma, the mesosoma and the metasoma, the latter two representing subdivisions of the opisthosoma. The prosoma supposedly includes, as mentioned above, the ocular segment and post-ocular segments 1–6. These segments are supposed to dorsally form the prosomal shield. Ventrally, (proximal portions of) appendages of post-ocular segments 1–4 form the feeding apparatus. Appendages of post-ocular segment 1, the chelicerae, are small pincers that can squash","PeriodicalId":9332,"journal":{"name":"Bulletin of Geosciences","volume":"1 1","pages":"389-408"},"PeriodicalIF":1.9,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49552658","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}

Part of this success has been attributed to the niche differentiation between larvae and adults. Due to this, in most cases, adult holometabolans avoid exploitation competition with their own offspring. This has obviously led to highly specialised adults, but also to highly specialised larval forms. Caterpillars of butterflies (Lepidoptera) and sawflies (Hymenoptera) are highly efficient herbivores, transforming plant parts into insect biomass. Larvae of other groups have different ecological roles. The larval forms of neuropterans, lacewings, are highly specialised predators (with only few exceptions). Their mouthparts form two forward oriented (prognathous) venom-injecting stylets (e.g. Aspöck et al. 2001, 2012; Beutel et al. 2010); each mandible (upper jaw) forms a stylet with an enditic protrusion (generally interpreted as the lacinia) of the next posterior mouthpart (maxilla; lower jaw). Within the diverse subgroups of Neuroptera many different variations of this basic scheme have evolved. Many of these stylets are curved. In this way the piercing tips are facing towards each other. This arrangement is an almost ideal solution for the mechanical challenge that while piercing a prey a counteracting force is necessary; otherwise the piercing animal would simply push itself back from the prey. In counteracting mouthparts, the counteracting force is provided by the other mouthparts. This mechanical solution is not only realised in many neuropteran larvae, but also in the venom­injecting maxillipeds of most centipedes (see Haug et al. 2014 and references therein for a detailed discussion) as well as the venom­injecting chelicerae of labidognathan spiders. Among the neuropteran larvae with curved stylets also many variations occur.

The approximate time span of individual beds and couplets are a basic requirement for finetuned cyclostratigraphy based on lithological changes. Limestone-marl alternations are often used for this kind of approach, even though correlation of individual limestonemarl couplets over long distances have been questioned in the last 25 years by studies investigating their specific diagenetic processes (among others Munnecke & Samtleben 1996; Böhm et al. 2003; Westphal et al. 2010, 2015; Bádenas et al. 2012; Gygi 2012; l’Heureux 2018). As the precise duration of the deposition of a single bed normally cannot be determined, the temporal range of the whole succession is usually divided by the number of couplets (Schlager et al. 1998). The resulting time span of single beds/couplets thus varies from several 1000 (e.g. millennial cycles) to several 100,000 (Milankovitch cycles) years (Hilgen et al. 2003; see compilation in Strasser et al. 2006). Several problems, however, arise through this method. Apart from hiatuses and the difficulty of defining the precise age of a couplet, fluctuating sedimentation rates are a further limiting factor for any fine-tuned resolution (Sadler 1981). Sadler (1981) and later Schlager et al. (1998) formulated a dependence of the calculated sedimentation rate on the length of the observed interval, with a reduced rate from larger observation intervals (Sadler effect). Or, in other words: “We invariably find that the rock record requires only a small fraction, usually 1 to 10 per cent, of the available time, even if we take account of all possible breaks in the sequence” (van Andel 1981), which means that more than 90% of the time is not recorded in the respective sediments, not even in the deep sea. So how do we know if this missing time is still reflected in the cyclicity (e.g. only 10% of every climatic cycle is recorded)?

Before the 1950s very few papers focused specifically on fossil polyplacophorans. A notable exception is the work of Šulc (1934), which has remained an indispensable reference for any later study on chitons from the Cenozoic of Europe. The large majority of European chiton records are from Neogene, while chitons from the Paleogene are poorly known, with greater prevalence of records from Eocene (Cossmann 1888, 1922; Cossmann & Pissarro 1900, 1905; Wrigley 1943; Bielokrys 1999, 2000; Dell’Angelo et al. 2011, 2015a; Cherns & Schwabe 2017).

Herein, depending on the investigation method, between 0.7% and 13% of the samples contained conspecific prey fish and/or prey fish remains. In total 1.6% contained remains of amphipod shrimps. Concerning T. intermedius , prey (arthropod) remains could be found only in one sample (3.4%). Similarly, only one (6.6%) of the bowfins ( C. kehreri ) and none of the gars ( A. messelensis ) contained such remains. The pharyngeal jaws of R. minuta exhibit two basic types of dentition. One is characterized by strong, flattened (“molariform”) pharyngeal teeth, and the other by more delicate and slender (“papilliform”) ones. This polymorphism may be indicative of a beginning or advancing speciation. The different morphotypes probably originated in adjacent water bodies (allopatric) rather than in Lake Messel itself (sympatric). The results were discussed with particular attention to extant comparable species. The high rate of evacuated digestive tracts in R. minuta very probably results from a shortage of suitable prey, and possibly also from environmental restrictions. For the other species, different factors, like diurnal or seasonal fluctuations may have played a more important role. For R. minuta , a diet switch from predominantly arthropods to fish, especially a switch to T. intermedius as a main prey, can be discarded.
