“…The tribe Armantomyini diverges early (approximately 33.16 Ma) from the remaining species of the ingroup. Its origin is set up at about 26.10 Ma in Spain, then it spread to France and also entered Central Europe (Germany, Switzerland; Gómez‐Cano et al., 2011, 2014; Prieto et al., 2019). These results support the conclusions of Lu et al.…”

Relative performance of Bayesian morphological clock and parsimony methods for phylogenetic reconstructions: Insights from the case of Myomiminae and Dryomyinae glirid rodents

Extinct organisms provide crucial information about the origin and time of origination of extant groups. The importance of morphological phylogenetics for rigorously dating the tree of life is now widely recognized and has been revitalized by methodological developments such as the application of tip-dating Bayesian approaches. Traditionally, molecular clocks have been node calibrated. However, node-calibrations are often unsatisfactory because they do not allow the fossil age to inform about phylogenetic hypothesis. The introduction of tipcalibrations allow fossil species to be included alongside their living relatives, and the absence of molecular sequence data for these taxa remedied by supplementing the sequence alignments for living taxa with phenotype character matrices for both living and fossil taxa.So, only phylogenetic analyses that take into account morphological characters can incorporate both fossil and extant species. Herein we present an unprecedented morphological dataset for a vast group of glirid rodents, to which different phylogenetic methodologies have been applied. We have compared the tree topologies resulting from 2 traditional parsimony and Bayesian phylogenetic approaches and calculate stratigraphic congruence indices for each. Bayesian tip-dated clock methods seem to outperform parsimony with our dataset. The strict consensus tree recovered by tip-dating invalidates the classic classification and allow to propose dates for the divergence and origin of the different clades.

“…The positions of MN4 Czech localities are speculative, since no biostratigraphic data for all localities is available. Age and chronological position of the localities mentioned in the figure is based on works of Bolliger (1992) ; Steininger (1999) ; Bulot & Ginsburg (1996) ; Aguilar et al (2003) ; Bulot, Antoine & Duranthon (2009) ; Reichenbacher et al (2013) ; Ruiz-Sánchez et al (2013) ; Hordijk et al (2015) ; Prieto et al (2018) ; Prieto et al (2022) ; Jovells-Vaqué & Casanovas-Vilar (2021) .

“…The following standards are adhered to: the Miocene time scale and biostratigraphy are based on the International Chronostratigraphic Chart ( Cohen et al, 2020 ), the Central and Eastern Paratethys boundaries follow Gozhyk et al (2015) and Kováč et al (2018) ; MN-zones for Western (left) and Central (right) Europe are as in Steininger (1999) and Hilgen, Lourens & Van Dam (2012) . The age and chronological position of the localities in the text and figures are based on all the following: Bolliger (1992) ; Steininger (1999) ; Bulot & Ginsburg (1996) ; Aguilar et al (2003) ; Bulot, Antoine & Duranthon (2009) ; Reichenbacher et al (2013) ; Ruiz-Sánchez et al (2013) ; Hordijk et al (2015) ; Prieto et al (2018) ; Prieto et al (2022) and Jovells-Vaqué & Casanovas-Vilar (2021) .…”

Background Melissiodon is a rare cricetid genus endemic to Europe, known from the Early Oligoceneto the Early Miocene. It is usually a very rare find, and even in the few localities where Melissiodon remains are found, those are scarce and fragmentary. Only a few Central European localities have yielded rich remains of the genus. Currently, two species are known from the Early Miocene: Melissiodon schlosseri, which is based on two teeth from the MN2 German locality of Haslach and only found in two other sites of similar age (Ulm-Uniklinik and La Chaux, from Germany and Switzerland respectively); and Melissiodon dominans, found in MN3 and MN4 localities across Europe, even though the scarce and fragmentary remains make some of these attributions dubious. For that reason, Melissiodon dominans has become a catch-all species. However, Mokrá-Quarry represents one of the best documented findings of Melissiodon remains from MN4 localities of Europe. Methods The Melissiodon assemblage from Mokrá-Quarry has been studied thoroughly, providing metrics and detailed descriptions of all teeth positions, as well as complete comparisons with other MN3 and MN4 localities bearing Melissiodon remains. Results In this work, new remains of Melissiodon have been identified as a new morphotype that clearly differs from Melissiodon dominans by its unique m1 morphology but still shows some resemblance with Melissiodon schlosseri. Based on that, we here propose the hypothesis of an evolutionary lineage starting from Melissiodon schlosseri, diverging from the lineage leading towards Melissiodon dominans. With this finding, there are at least two different taxa of Melissiodon known during the Early Miocene, prior to the genus extinction. This study arises the certainty that the evolution history of the genus is more complex than previously thought and that more studies are necessary to elucidate it, including a complete revision of the type material of Melissiodon dominans and Melissiodon schlosseri in the light of current knowledge of the genus, which will help to elucidate the attribution of the populations from Mokrá-Quarry. For the time being, the assemblage presented here is referred as Melissiodon aff. schlosseri.

“…This pattern has been observed in Ribesalbes-Alcora and all the splitting stages have been noted, from an anteroloph with a small constriction to the fusion with the protoloph. A similar species comparable in size is Simplomys hugi Prieto, Lu, Maridet, Becker, Pirkenseer, Rauber & Peláez-Campomanes, 2019 but in this Central European species, the centroloph is lacking and the anteroloph is never divided (Prieto et al 2019). An additional characteristic in our material is the presence of a small pre-anteroloph crest, which gives the tooth greater robustness.…”

“…The stratigraphic range of S. simplicidens extends from the Early Miocene (MN2) to the Middle Miocene (MN5) (García-Paredes et al 2009; Prieto et al 2018; 2019). This species was described by De Bruijn (1966) based on the simplest material of the genus Pseudodryomys from the Calatayud-Montalbán Basin; later García-Paredes et al (2009) described the new genus Simplomys to include this species.…”
