New internally structured decapod microcoprolites from Germany (Late Triassic/Early Miocene), Southern Spain (Early/Middle Jurassic) and Portugal (Late Jurassic): Taxonomy, palaeoecology and evolutionary implications

Early Cretaceous crustacean microcoprolites from Sierra de la Cara Cura, Neuquén Basin, Argentina: Taphonomy, environmental distribution, and stratigraphic correlation

“…upper Carboniferous of the Ural Mountains (Masse and Vachard, 1996), and upper Permian of Oman , but is most widespread in the Upper Triassic in the USA (Kristan-Tollmann and Tollmann, 1983), Peru (Senowbari-Daryan and Stanley, 1986), and Italy . It was also described from Jurassic beds in Spain (Schweigert et al, 1997), Germany (Helm and Schülke, 2004) and France (Senowbari-Daryan et al, 2007), from the Lower Cretaceous of Hungary (Bujtor, 2012), and from the Cretaceous of MIT Guyot in the northwestern Pacific Ocean (Senowbari-Daryan and Grötsch, 1992). Material.…”

“…According to Schweigert et al (1997), Favreina belandoi cannot be characterized by its total number of internal canals, but its diagnosis is determined by the shape and arrangement pattern of canals which is correlated with the diameter of the microcoprolites. This ichnospecies differs from all other species of Favreina by the presence of the pair of isolated canals in different growth stages of the microcoprolites.…”

Crustacean microcoprolites from Jurassic (Oxfordian) hydrocarbon-seep deposits of Beauvoisin, southeastern France

“…It is not reported from the Jurassic or later time intervals. Leinfelder (in Schweigert et al 1997 Remarks: Palaxius is typified by canals of crescentlike outline in cross-section. The size, number and arrangement pattern of canals are used to classify the coprolite at the ichnospecies level.…”

Geology of the eastern slopes of the Simbruini Mts. between Verrecchie and Capistrello (Central Apennines – Abruzzo, Italy)

“…Although in the literature oolitic-bioclastic intercalations are described, along with abundant micropaleontological assemblages (Damiani et al, 1991(Damiani et al, , 1998, the outcropping portion of the unit only shows oligotypic assemblages, characterized by abundant Favreina prusensis and Favreina spp., and rare Cladocoropsis mirabilis. F. prusensis is found, in the successions described for the sheet #376 'Subiaco' of the Geological map of Italy (Servizio Geologico d'Italia, 1998), in Berriasian-Valanginian beds (see also Kuss & Senowbari-Daryan, 1992), but in literature it is commonly described in Kimmeridgian-Tithonian strata (Molinari-Paganelli, Pichezzi, & Tilia -Zuccari, 1980;Schweigert, Seegis, Fels, & Leinfelder, 1997). The occurrence of Cladocoropsis mirabilis, which is a marker of the lower Callovian -upper Kimmeridgian (Chiocchini et al, 2008), allows to tentatively ascribe the outcropping portion of this unit to the Kimmeridgian.…”
