Recent advances in the fossil record, anatomy, and evolutionary history of South American turtles allow a thorough analysis their changes diversity, to identify several major extinction events. With onset breakup Pangea Middle Jurassic, begin diversify, giving rise main turtle clades some which survive until present. The first peak diversity was achieved Early Cretaceous. A event is recognized at end Cretaceous, affecting mainly pelomedusoids northern latitudes coinciding with final...
Abstract Modern morphometric-based approaches provide valuable metrics to quantify and understand macroevolutionary macroecological patterns processes. Here we describe TriloMorph, an openly accessible database for morpho-geometric information of trilobites, together with a landmark acquisition protocol. In addition morphological traits, the contains contextual data on chronostratigraphic age, geographic location, taxonomic lithology landmarked specimens. this first version, dataset has...
Abstract A new dalmanitid trilobite is described from the early Silurian (Telychian) Waukesha Biota in Wisconsin, USA, best known for its variety of exceptionally preserved arthropods. Waukeshaaspis eatonae genus species most common found Biota, numbering ~200 specimens, allowing a thorough description dorsal exoskeleton. This taxon has combination characters unique to Dalmanitidae, including distinct embayment on posterior margin pygidium. Embayments are rare dalmanitids, having instead...
Abstract The dalmanitid trilobite Kasachstania Maksimova, 1972, previously reported from the Lower Devonian of Kazakhstan and North America (USA) upper Silurian–Lower South (Bolivia Argentina), is revised. kasachstanica (Balashova in Maksimova,1968) K. septicostata (Maksimova, 1968) are regarded as junior synonyms type species saryarkensis 1960), all locality central (northern Balkhash). On basis a new diagnosis, ulrichi (Delo, 1940) Emsian United States, asiatica 1968), pristina alperovichi...
Three new Lower Devonian dalmanitid trilobite taxa are recognized from the Talacasto Formation in Precordillera Basin, Argentina, which includes two monospecific genera (Ivanites leonorae n. gen., sp. and Aguaditaspis mediaspina sp.), one additional genus species left open nomenclature. These combine characters of subfamilies Dalmanitinae Vogdes, 1890 Synphoriinae Delo, 1935, challenging their taxonomic distinction. Forty percent dalmanitids high paleolatitudinal basins southwestern Gondwana...
