“…The West Siberian rodents of the late early Pleistocene are characterized by the predominance of voles with unrooted cheekteeth, the first appearance of Microtus hintoni Schrank, 1798, and the general dominance of voles of the genus Allophaiomys Kormos, 1932. This Razdolean faunal complex partially correlates with the eastern European biochrons MQR8-7 or with the Tamanian faunal complex (∼0.8-1.2 Ma) (Zazhigin, 1980;Krukover, 2007;Pokatilov, 2012;Tesakov et al, 2020). The next biostratigraphic stage in the evolution of the West Siberian fauna is the Vyatkino faunal complex and corresponds with the disappearance of voles of the genus Allophaiomys and the rise of the Microtus group (Zazhigin, 1980).…”

“…This complex is divided into early, middle, and late stages by evolutionary level in the Prolagurus-Lagurus and Microtus group lineages (Krukover, 1992(Krukover, , 2007. The Vyatkino complex may be partly correlated with the eastern European biochrons MQR7-3 or with the Tiraspol faunal complex (∼0.4-0.8 Ma) (Zazhigin, 1980;Tesakov et al, 2020). The appearance of Stenocranius gregalis Pallas, 1779 and Lagurus lagurus Pallas, 1773 in the second half of the Middle Pleistocene marks the end of the Vyatkino stage.…”

Zokors (Myospalacinae) continue to be the center of systematics discussions. Phylogenetic schemes based on molecular data do not always agree with each other, nor can phylogenetic schemes based on paleontological material be complete due to the only-partial description of West Siberian zokors. This paper tries to fill this gap and presents a description of the West Siberian lineage from the late early Pleistocene to the present, together with an analysis of molar development in other zokor lineages. We describe two new species and one subspecies (Myospalax myospalax krukoveri n. ssp., Myospalax convexus n. sp., Prosiphneus razdoleanensis n. sp.) ancestral to the extant Myospalax myospalax Laxmann, 1769. We also reveal differences in the ontogeny of molars of modern species that were not previously detailed. These differences, together with paleontological data, indicate that in the West Siberian lineage, peramorphosis occurred in the structure of the chewing surface (with the exception of the lower m1), whereas in all other zokor lineages, there was pedomorphosis. On the basis of these results, we suggest a new view on the systematics of Myospalacinae. UUID: http://zoobank.org/b06d6c99-1648-454b-9b95-4d869bfe8bdc

“…Six different types of biomineral were analysed: calcitic Bithynia opercula, slug plates and worm granules; and aragonitic Arianta, Cepaea and Fruticola shells (Table 1). The only material for which full closed system tests and an aminostratigraphic framework had previously been developed was the Bithynia opercula (Penkman et al, 2013;Tesakov et al, 2020). Small-scale pilot and unpublished IcPD studies had previously been undertaken on Arianta and Cepaea shell, slug plates and worm granules, but this represents the first widespread study on these fossil materials, as well as the first IcPD data on Fruticola shell.…”

“…Previous studies have shown that the intra-crystalline fraction of Bithynia opercula exhibits closedsystem behaviour (Penkman et al, 2011;Tesakov et al, 2020), so its presence in a small number of the Swiss deposits made it an obvious target for aminostratigraphy. Where closed-system behaviour is evident, then protein decomposition should depend solely on time and temperature (e.g.…”

Here we develop an amino acid chronology to help establish a dated sequence for the important Early Pleistocene Höhere and Tiefere Deckenschotter lithostratigraphic units, as well as other Quaternary deposits from the Swiss Plateau. Age discrimination is possible between the Quaternary sites from the Swiss Plateau in six different biominerals: Bithynia opercula, shell fragments from Fruticola, Arianta and Cepaea, slug plates and worm granules. This chronology is compared with new and existing dating information derived from palaeomagnetic data, pollen, lithostratigraphy and numerical dating methods (such as optically stimulated luminescence; OSL), as well as biostratigraphic data derived from a study of Early to Late Pleistocene molluscan faunas from the Swiss Plateau. In general, the stratigraphy has been validated, with some new chronological insights at some of the few sites.

“…In Bithyniid snails, the operculum (the structure that closes the aperture when the snail withdraws into its shell) is mineralized in the more stable form of calcium carbonate [calcite ( 100 )] and preserves the IcP well in the fossil record. AA geochronology of Bithynia opercula has allowed correlation of Quaternary deposits with the MIS record ( 101 – 103 ), enabling archaeological sites to be correlated with specific interglacials and in some cases, to individual parts of the interglacial. This has provided an independent test of the temporal patterns in hominin occupations ( Fig.…”

Despite the vast array of different geochronological tools available, dating the Paleolithic remains one of the discipline’s greatest challenges. This review focuses on two different dating approaches: trapped charge and amino acid geochronology. While differing in their fundamental principles, both exploit time-dependent changes in signals found within crystals to generate a chronology for the material dated and hence, the associated deposits. Within each method, there is a diverse range of signals that can be analyzed, each covering different time ranges, applicable to different materials and suitable for different paleoenvironmental and archaeological contexts. This multiplicity of signals can at first sight appear confusing, but it is a fundamental strength of the techniques, allowing internal checks for consistency and providing more information than simply a chronology. For each technique, we present an overview of the basis for the time-dependent signals and the types of material that can be analyzed, with examples of their archaeological application, as well as their future potential.
