Data from: Spatiotemporal variation in completeness of the early cynodont fossil record and its implications for mammalian evolutionary history
<p>Mammals are the only surviving group of Cynodontia, a synapsid clade that first appears in the fossil record in the late Permian, ~260 million years ago. Here, using three metrics that capture skeletal completeness, we quantify the quality of the early cynodont fossil record in time and space to evaluate the impact of sampling and preservational biases on our understanding of the group's evolutionary history. There is no consistent global sampling signal for early cynodonts. Completeness of the cynodont fossil record increases across the Permian/Triassic boundary, peaking in the Early–early Late Triassic. This peak is dominated by specimens from southern Africa and South America, where a highly seasonal climate likely favoured preservation. Completeness is generally lower thereafter, correlated with a shift from a Gondwanan to a predominantly Laurasian fossil record. Phylogenetic and stratigraphic congruence in early cynodonts is high, although their fossil record exhibits less skeletal completeness overall than other tetrapod clades, including the contemporaneous anomodont synapsids. This discrepancy could be due to differences in the diagnosability of their fossils, especially for small-bodied species. Establishing the timing and assembly of derived ('mammalian') anatomical features in Cynodontia is obscured by sampling. Two of the major nodes at which acquisition of mammalian features is concentrated (Cynodontia and Mammaliamorpha) suffer from lengthy intervals of poor sampling prior to becoming abundant parts of tetrapod faunas. Low completeness in these intervals limits our ability to determine when certain 'key' mammalian characteristics evolved, or to identify the selective pressures that might have driven their origins.</p>
Data from: New records of the late Pliensbachian to early Toarcian (Early Jurassic) gladius-bearing coleoid cephalopods from the Ya Ha Tinda Lagerstätte, Canada
The Ya Ha Tinda Lagerstätte from Alberta, Canada, is the first Jurassic marine Konservat-Lagerstätte from North America and hosts a substantial collection of exceptionally preserved fossil Vampyropoda specimens. Vampyropods are soft-bodied cephalopods (coleoids) characterized by eight arms and an internalized chitinous shell (gladius). Due to their lack of hard parts, Vampyropoda have a fragmentary fossil record, largely limited to exceptional Lagerstätten deposits. Excavations at Ya Ha Tinda have uncovered sixteen vampyropod fossils from Pliensbachian and Toarcian strata, making it the largest deposit of Vampyropoda found outside of the Tethys Ocean (Europe and the Middle East) for the Jurassic. Here, we present a taxonomic analysis of the Ya Ha Tinda Vampyropoda specimens and the first comprehensive study of Early Jurassic vampyropods from North America. In total, fourteen specimens have sufficient morphological details preserved on the gladius for taxonomic descriptions. Two specimens are identifiable only to the suborder Loligosepiina (one to the family Geopeltidae), while the remaining twelve specimens are identified to the genus level; six Paraplesioteuthis, three Loligosepia, one Geopeltis, one Parabelopeltis, and one Jeletzkyteuthis. The discovery of Loligosepia cf. aalensis within Pliensbachian strata pushes back the earliest occurrence of this taxon from the early Toarcian to the late Pliensbachian. With the exception of Paraplesioteuthis, this is the first time these genera have been found outside of Europe for the Jurassic; therefore, this study significantly expands their palaeogeographic range. Furthermore, with established high-resolution bio and chemostratigraphy, specimens can be assigned to ammonite zones and placed in context of the global Toarcian Oceanic Anoxic Event.
Data from: The early record of halysitid tabulate corals, and morphometrics of Catenipora from the Ordovician of north-central China
Catenipora is one of the most common tabulate coral genera in the Upper Ordovician Jinghe and Beiguoshan formations on the southern margin of the Ordos Basin, north-central China. We distinguish and identify the species of Catenipora using multivariate morphometric procedures. Cluster analysis based on morphological characters of coralla yields a dendrogram showing five morphospecies. The validity and distinctiveness of the morphospecies are evaluated by discriminant analysis and non-metric multidimensional scaling. To identify the species represented by the morphospecies, type specimens of species that are morphologically similar from north-central China (Sino-Korean Block) and surrounding palaeocontinents are compared with the morphospecies by non-metric multidimensional scaling and descriptive statistics. The result indicates that one morphospecies represents C. daliangensis (Yu), another represents C. subovata Yu, and the others are considered to be new species named C. tongchuanensis, C. jingyangensis and C. tiewadianensis. Catenipora tongchuanensis from the middle of the Jinghe Formation (Sandbian; early Late Ordovician) is the earliest confirmed halysitid tabulate. Species of Catenipora in north-central China (Sino-Korean Block) show the highest morphological diversity (i.e. disparity) in terms of corallite size and shape, compared with other palaeocontinents in China. Species of Catenipora in North Qilian share more common components with those from north-central China than any other palaeocontinent in China. The different morphological characteristics in terms of corallite shape and ranks in some Katian species of Catenipora from East Junggar, Mongolia, South China and Estonia suggest that some species may have originated separately during the Great Ordovician Biodiversification Event, and Catenipora is possibly polyphyletic.
Data from: Differential drivers of benthic foraminiferal and molluscan community composition from a multivariate record of Early Miocene environmental change
Climate changes are multivariate in nature, and disentangling the proximal drivers of biotic responses to paleoclimate events requires time series of multiple environmental proxies. We reconstruct a multivariate time series of local environmental change for the early Miocene Newport Member of the Astoria Formation (20.26–18 Ma), using proxies for temperature (δ18O), productivity (δ13C), organic carbon flux (Δδ13C), oxygenation (δ15N), and sedimentary grain size (% mud). Our data suggest increases in productivity and declines in oxygenation on the Oregon shelf during this interval of global warming. We evaluate the association of individual environmental factors, and combinations of factors, with changes in faunal composition observed in benthic foraminiferal and molluscan communities collected from the exact same sediments as the environmental data. The δ15N values are the most parsimonious correlates with major changes in foraminiferal composition, whereas molluscan composition is most closely related to δ13C values, suggesting that different components of the environment are influencing each group. When the proxies that have the best supported relationships with the faunal gradients are removed from the analyses to simulate the absence of those proxy data, significant relationships between the faunal gradients and the remaining environmental proxies can still be found. This suggests that environmental drivers can be incorrectly attributed to faunal changes when key proxy data are missing. Paleoecological studies of biotic response that test multiple environmental drivers for multiple taxonomic groups are powerful tools for identifying the ecological consequences of past warming events and the regional drivers of ecological changes.
