Linking southern Poland and northern Germany: Campanian cephalopods, inoceramid bivalves and echinoids

The Campanian strata in the Wolbrom-Miechów area at Wierzchowisko, Jeżówka and Rzerzuśnia (i.e., the southwestern part of the Miechów Trough, southern Poland) have been studied in some detail. Collections of macrofossils available to date include generally well-preserved and diverse cephalopods (ammonoids, coleoids), inoceramid bivalves and irregular echinoids of considerable stratigraphic and correlative value. For the present paper, taxa which allow a preliminary correlation with northern Germany (Lägerdorf, Lehrte West Syncline and Münsterland Basin) are singled out for brief discussion. Stratigraphically useful taxa include the ammonites Pachydiscus (P.) haldemsis (SCHLÜTER), Lewyites elegans (MOBERG), Scaphites (S.) hippocrepis III sensu COBBAN, S. (S.) gibbus SCHLÜTER and Trachyscaphites spiniger spiniger (SCHLÜTER), the coleoids Belemnitella ex gr. mucronata (VON SCHLOTHEIM) and Gonioteuthis quadrata (DE BLAINVILLE), the inoceramids Cataceramus dariensis (DOBROV & PAVLOVA), ‘Inoceramus’ azerbaydjanensis ALIEV and ‘I.’ agdjakendsis ALIEV, and the echinoids Offaster pilula (LAMARCK), Galeola papillosa (LESKE), Echinocorys ex gr. subglobosa/turrita, E. ex gr. conica, Micraster (Gibbaster) ex gr. fastigatus/stolleyi and M. (M.) ex gr. schroederi/glyphus. The ammonite fauna, which is dominated by pachydiscids and diplomoceratids, is closely comparable to that from the Busko Zdrój area (i.e., the southeastern part of the Miechów Trough), but hoplitoplacenticeratids are still unknown from the Wolbrom-Miechów area which, taken together with inoceramid data, may point to a gap in the upper Lower Campanian (equivalent of conica/mucronata Zone)

Comment on the letter of the Society of Vertebrate Paleontology (SVP) dated April 21, 2020 regarding 'Fossils from conflict zones and reproducibility of fossil‑based scientific data': Myanmar amber

Recently, the Society of Vertebrate Paleontology (SVP) has sent around a letter, dated 21st April, 2020 to more than 300 palaeontological journals, signed by the President, Vice President and a former President of the society (Rayfield et al. 2020). The signatories of this letter request significant changes to the common practices in palaeontology. With our present, multi-authored comment, we aim to argue why these suggestions will not lead to improvement of both practice and ethics of palaeontological research but, conversely, hamper its further development. Although we disagree with most contents of the SVP letter, we appreciate this initiative to discuss scientific practices and the underlying ethics. Here, we consider different aspects of the suggestions by Rayfield et al. (2020) in which we see weaknesses and dangers. It is our intent to compile views from many different fields of palaeontology, as our discipline is (and should remain) pluralistic. This contribution deals with the aspects concerning Myanmar amber. Reference is made to Haug et al. (2020a) for another comment on aspects concerning amateur palaeontologists/citizen scientists/private collectors

First record of the enigmatic coleoid genus Longibelus from Sakhalin (Far East Russia): a contribution to our understanding of Cretaceous coleoid habitats in the Pacific Realm

Abstract A newly collected specimen of the enigmatic coleoid genus Longibelus is recorded from lower Turonian strata along the River Shadrinka in Sakhalin (Russian Far East). To date, this is the first record of Late Cretaceous coleoid cephalopods from the island and, in fact, from the entire Pacific coast of the Russian Federation. Lithological characteristics, coupled with published geochemical analyses (δ13C and Corg content), suggest the habitat of this coleoid taxon to have been the middle to outer (i.e. distal) shelf. Its provenance from the stratigraphical level that is known as the Scaphites Event, characterised by a mass occurrence of Scaphites and Yesoites, may be indicative of occasional or marginal overlap in ranges, rather than life in similar habitats. On the basis of lithological features and in view of the extremely rare occurrence of Longibelus in rich ammonite assemblages with clear ecological/bathymetric preferences, the natural habitat of Longibelus may have comprised neritic to mesopelagic zones over distal shelves and slopes

ignabergensis Carlsson 1953

Pycnolepas ignabergensis Carlsson, 1953 Original description. Carlsson (1953: 23, pl. 5, fig. 10; pl. 6, figs 1, 2). Type. Holotype is SMNH Ar. 8742, a left scutum. Locality and stratigraphy. Ignaberga, Skåne (southern Sweden); uppermost lower Campanian (c. 81 – 80 Ma), Belemnellocamax mammillatus Zone (see Christensen, 1975, 1997a, b). Remarks. Of this species, only two scuta and a single tergum are known to date; ornament consists of numerous transverse and longitudinal ridges (comparable to some representatives of P. rigida; see e.g. Withers, 1935: pl. 47, fig. 5); comparatively narrow apicobasal ridge. Carina, rostrum, upper latus and imbricating plates unknown. Occurrence. Known exclusively from the type locality; no subsequent records.Published as part of Jagt, John W. M., Zonova, Tatiana D. & Jagt-Yazykova, Elena A., 2007, A review of the brachylepadomorph cirripede genus Pycnolepas, including the first record of an Early Cretaceous species from the Russian Far East *, pp. 33-47 in Zootaxa 1545 on page 39, DOI: 10.5281/zenodo.17797

Pollicipes rigida

Pycnolepas rigida (J. de C. Sowerby, 1836) Original description. J. de C. Sowerby (1836: 335, pl. 11, fig. 6, as Pollicipes rigidus). Type. Lectotype, designated by Withers (1914: 170), is a scutum illustrated by J. de C. Sowerby (1836); current whereabouts unknown. Locality and stratigraphy. Folkestone, southeast England; lower Gault (middle Albian). Remarks. Va l v e s o f P. rigida are transversely, and generally also longitudinally, ridged; scutum elongatetriangular, with basilateral portion produced and with narrow wall-sided ridge curving from apex to basilateral angle; tergum with apical portion much curved towards scutum and with ridge like that of scutum, curving from apex to basal angle; width of imbricating plates exceeding height. Lot NHMM 2006 0 20 (leg. J.S.H. Collins), comprising isolated scuta, terga, rostra and carinae from the Albian of Bedfordshire (England), shows the wide range of variation of this taxon, expressed in valve proportions (length/width ratio), ornament (in particular, number and strength of longitudinal and transverse ribs) and width of apicobasal ridge (see Withers, 1935). Occurrence. Lower Albian (c. 108 – 107 Ma) to middle (?upper) Cenomanian (c. 93 – 92 Ma), England (Bedfordshire, Kent, Cambridge area) and France (Yonne, Haute-Marne); common in the lower Albian Leymeriella tardefurcata Zone, ranging throughout overlying Albian zones and extending into the Chalk Marl and higher (Cenomanian, Schloenbachia varians and Holaster [= Crassiholaster] subglobosus zones) (Collins, 1980; Carriol & Collins, 2000; Owen, 2002; Smith & Wright, 2003).Published as part of Jagt, John W.

Pollicipes orientalis Kolosvary 1966

Pycnolepas orientalis Kolosváry, 1966 (nomen dubium) Original description. Kolosváry (1966: 130, text-fig. 2). Type. Not indicated; current whereabouts of material unknown. Locality and stratigraphy. Kuznataj (= River Kuzna-chaj, Azerbaijan); Upper Cretaceous (exact level not specified). Remarks. The type lot (collected 1958; leg. V.G. Nikitin) of this form consists of isolated capitular valves; Kolosváry referred to these as scutum, carina, carinolaterale, tergum, rostrum and supralaterale. As noted by Collins (1980: 21), the ‘scutum’ in Kolosváry’s fig. 2 a clearly is a tergum, while the ‘tergum’ of his fig. 2 d is a scutum; that this was intentional can be seen from the description and reconstruction of the capitulum (Kolosváry, 1966: fig. 7). Kolosváry failed to explain why this form should have had three pairs of lateral valves, while the genus Pycnolepas has a single pair (see Withers, 1914, 1935). Alekseev (1979: 17) clarified the provenance of the material by noting that (translated), ‘In the same year, G. Koloshvary (Kolosvary, 1966) based on material from Caucasus, received from O.S. Vialov, briefly described the new species Pycnolepas orientalis (Azerbaijan, River Kuzna-chaj, Upper Cretaceous) and the new subspecies Zeugmatolepas mockleri armenicus (Armenia, Maastrichtian), without pictures giving only schematic drawings’. We consider it best to treat P. orientalis as a nomen dubium until the types are traced, or new material is collected, so as to allow a proper interpretation of this form. Occurrence. Known only from the type area; no subsequent records.Published as part of Jagt, John W.

industriosa Jagt 2007

Pycnolepas industriosa Jagt, 2007 Original description. Jagt (2007: in press). Material. A single rostrum, NHMM 2003 015/ 1. Locality and stratigraphy. Altembroeck (Voer, northeast Belgium); Gulpen Formation, Vijlen Member, Interval 4, lower upper Maastrichtian (c. 70 Ma, Belemnitella junior Zone) (Jagt et al., 1995; Jagt, 2007). Remarks. The sole rostrum known is medium-sized, widely semi-conical, strongly convex transversely and subcarinate; ornament consists of longitudinal and transverse ridges, resembling that of P. landenica (see below) which also has a similar L/W ratio. No other capitular valves or imbricating plates known. Occurrence. Known exclusively from the type locality.Published as part of Jagt, John W.
