title: A High Spatial Resolution Satellite Remote Sensing Time Series Analysis of Cape Bounty, Melville Island, Nunavut (2004–2018)

description: Changes in vegetation have been observed in areas of the Arctic due to changing climate. This study examines a normalized difference vegetation index (NDVI) time series (2004–2018) of high spatial resolution satellite data (i.e., IKONOS, WorldView-2, WorldView-3) to determine if vegetation abundance has changed over the Cape Bounty Arctic Watershed Observatory, Melville Island, Nunavut. Image data were corrected to top-of-atmosphere reflectance and normalized for time series analysis using the pseudo-invariant feature (PIF) method. Percent vegetation cover measurements and indices derived from local climate data (growing degree days base 5 °C; GDD<sub>5</sub>) were used to contextualize NDVI trends in different vegetation types and within active layer detachments (ALDs). NDVI showed similar patterns within the different vegetation types and across the ALDs. There was no significant change in NDVI nor in GDD<sub>5</sub> over time. However, there were statistically significant (<i>p</i> 5 and NDVI for all vegetation types. Using field measurements with high spatial resolution remote sensing data helps link changes in NDVI with changes to vegetation and earth surface processes. The challenges of integrating high spatial resolution satellite data from different sensors in a time series analysis are also discussed.

title: Global aerodynamic parameters in 1982-2017 based on GIMMS LAI

description: The bulk surface properties, including canopy height (ht), zero-plane displacement height (d), and roughness length (z0) are crucial biophysical parameters that influence momentum, energy, and mass exchanges at the land-atmosphere interface. Here we provide a global estimate of bulk aerodynamic parameters during 1982-2017 at 0.05-degree spatial resolution and monthly temporal interval, using remote-sensed leaf area index, canopy height, and a turbulent transfer model. Two separate datasets are generated using GLASS LAI and GIMMS LAI. This dataset includes the products based on GIMMS LAI. Details can be found: Liu, Y., Guo, W., Huang, H., Ge, J., Qiu, B., 2021.

title: First Osteological Record of a Stegosaur (Dinosauria, Ornithischia) from the Upper Jurassic of South America

description: A stegosaurian humerus from the Oxfordian–Tithonian(?) Cañadón Calcáreo Formation of Chubut, Argentina, extends the fossil record of this clade of thyreophoran ornithischian dinosaurs to the Upper Jurassic of South America. The element shares the derived character of an oblique ridge extending from the deltopectoral crest towards the medial distal condyle with taxa such as <i>Kentrosaurus</i> and <i>Stegosaurus</i> and thus represents a derived representative of the clade. The presence of stegosaurs in the Cañadón Calcáreo Formation underlines the similarities of its dinosaur fauna with other Late Jurassic dinosaur faunas, such as the Morrison Formation of North America or the Tendaguru Formation of Tanzania, in at least broad systematic terms.

title: The Dawn of Desmatophocidae: A New Species of Basal Desmatophocid Seal (Mammalia, Carnivora) from the Miocene of Oregon, U.S.A.

description: Desmatophocidae (Mammalia, Carnivora) represents the first of the four major pinniped clades to appear in the fossil record. However, the majority of its known diversity consists of derived species and little is known about the nascence of this early pinniped lineage. Here we report the discovery of <i>Eodesmus condoni</i>, gen. et sp. nov., represented by a nearly complete cranium from the Burdigalian Iron Mountain Bed of the Astoria Formation from the central coast of Oregon, U.S.A. Notably, this specimen possesses nasolabialis fossae, a plesiomorphic trait shared with stem pinnipedimorphs and the basal phocid <i>Devinophoca</i> sp., but not with any other desmatophocid. Phylogenetic analysis (98 characters, 27 taxa) resolved <i>Eodesmus condoni</i> as the most basal desmatophocid yet described. Poor support for the monophyly of Otarioidea, Odobenidae, and Phocoidea demonstrate that high-level relationships within Pinnipedia have yet to be conclusively resolved. The identification of another desmatophocid species at the already pinniped-rich Iron Mountain Bed suggests that the approximately synchronous mid-Miocene Climatic Optimum played a role in this increase in pinnipedimorph species diversity. http://zoobank.org/urn:lsid:zoobank.org:pub:C9335617-3A0D-414A-937A-72C859C0075F

title: Revision of the Early Permian Dissorophid ‘<i>Dissorophus</i>’ <i>Angustus</i> (Temnospondyli: Dissorophoidea)

description: The temnospondyl ‘<i>Dissorophus</i>’ <i>angustus</i> from the lower Permian (Archer City Formation) of Texas is one of several neglected taxa assigned to Dissorophidae. It shares with other dissorophids the presence of median osteoderms along the tips of the vertebral neural spines, but in a unique arrangement of an anterior set of external and internal osteoderms from vertebrae 5–9 followed by a transition at vertebra 10 to a single series ending at vertebra 17. This pattern has been interpreted as either an evolutionary intermediate between dissorophids with a single row of osteoderms and those with a double set or a growth stage from a juvenile with a single row to an adult with a full series of external and internal osteoderms. Restudy of the holotype indicates it is a relatively mature individual, confirms the unique arrangement of the osteoderms, and expands the list of autapomorphies to include additional features of the osteoderms, otic notch, stapes, and pelvic girdle. The holotype is redescribed as <i>Diploseira angusta</i> gen. et comb. nov. Phylogenetic analysis supports <i>Diploseira</i> as a dissorophid, but fails to resolve its placement among those dissorophids with osteoderms other than it is not likely a eucacopine. Removal of wildcard taxa provides support for <i>Diploseira</i> as a dissorophine. Incorporation of additional characters of osteoderms into the phylogenetic analysis has revealed no apparent pattern, suggesting a species-specific evolution of dissorophid osteoderms.

title: New Fossils of <i>Mellivora Benfieldi</i> (Mammalia, Carnivora, Mustelidae) from Langebaanweg, ‘E’ Quarry (South Africa, Early Pliocene): Re-Evaluation of the African Neogene Mellivorines

description: We describe abundant new remains of the medium-sized mustelid <i>Mellivora benfieldi</i> from the early Pliocene site of Langebaanweg (South Africa). The specimens are from the Muishond Fontein Pelletal Phosphorite Member (MPPM) and the Langeberg Quartz Sand Member (LQSM). Novel dentognathic—upper dentition, alveolus for m2—and postcranial—humerus, metacarpal V, femur and calcaneus—information is provided. This sample enables us to review the taxonomic status of Mio–Pliocene African mellivorines. <i>Mellivora benfieldi</i> is distinguished from the middle–late Miocene ‘<i>Eomellivora</i>’ <i>tugenensis</i> from Ngorora Kenya by its smaller size, and a M1 protocone messially placed; from the late Miocene <i>Howellictis valentini</i> from Chad by greater dental size with more crowded lower premolars, and p3 with distal accessory cuspid; and from the late Miocene <i>Erokomellivora lothagamensis</i> from Kenya, by shorter p4 and buccolingually shorter m1 protoconid. It also differs from <i>H. valentini</i> and <i>Er. lothagamensis</i> in absence or residual presence of the m2 alveolus. We infer <i>M. benfieldi</i> was an opportunistic, medium-sized carnivoran with semifossorial abilities, comparable to its living relative <i>Mellivora capensis</i>. A cladistic analysis was performed and our phylogenetic results place <i>M. benfieldi</i> as the sister species of <i>M. capensis</i>. Mellivorini contains <i>M. benfieldi</i>, <i>M. capensis</i>, and <i>H. valentini</i>. Additionally, we also include <i>Er. lothagamensis</i> and the Indian <i>Promellivora punjabiensis</i>. We propose the creation of one new tribe within Mellivorinae: Eomellivorini (<i>Eomellivora</i> spp. + <i>Ekorus</i>). It shares a common ancestor with Mellivorini and is characterized by large size, a robust and sharp dentition, as well as a skeleton with cursorial adaptations.

title: New Specimens of <i>Scutellosaurus Lawleri</i> Colbert, 1981, from the Lower Jurassic Kayenta Formation in Arizona Elucidate the Early Evolution of Thyreophoran Dinosaurs

description: We describe new specimens of the ornithischian dinosaur <i>Scutellosaurus lawleri</i> Colbert, 1981, from the Lower Jurassic Kayenta Formation of Arizona and discuss their systematic importance. The new specimens represent at least 46 individuals and include two associated skeletons that preserve regions that were poorly known until now, including the skull and pelvis. Computed tomography (CT) assisted our interpretation of these specimens. Using an ornithischian data matrix, we first tested whether the two associated skeletons were justifiably assigned to <i>Scutellosaurus lawleri</i> and found that they group unequivocally with the holotype and paratype specimens. This enabled scoring of 35 character states that were previously unknown, raising the scoring completeness of <i>Scutellosaurus lawleri</i> from 52% to 67%. The results recovered <i>Lesothosaurus diagnosticus</i> as the basal-most member of Neornithischia, while corroborating the monophyly of Thyreophora and <i>Scutellosaurus lawleri</i> as its most basally branching member. In terms of numbers of specimens, <i>Scutellosaurus lawleri</i> is now the most abundant dinosaur known in any Early Jurassic vertebrate fauna. The presence of a second thyreophoran in the Kayenta Formation, along with the presence of Early Jurassic thyreophorans in Europe and Asia, suggests that Thyreophora may have originated in the northern hemisphere. The ornithischians from the Kayenta Formation support a pattern of dinosaurian diversification after the end-Triassic extinction in North America, if not a broader area, that was fueled by independent northward dispersals from the southern hemisphere, supporting dispersal as an early driver of dinosaurian evolution.

title: Skeletal Anatomy, Phylogenetic Relationships, and Paleoecology of the Eocene Urolophid Stingray <i>Arechia Crassicaudata</i> (Blainville, 1818) from Monte Postale (Bolca Lagerstätte, Italy)

description: In this paper we re-examine the taxonomy and systematic position of the Eocene stingrays from Bolca Lagerstätte which are traditionally assigned to <i>Urolophus crassicaudatus</i> (Blainville). The analysis of their tooth morphology supports an assignment to the Eocene stingray genus <i>Arechia</i> Cappetta, a taxon known from isolated teeth from the Ypresian-Lutetian of northern and western Africa. The teeth of the Bolca specimens differ from the type species <i>A. arambourgi</i> in some characters (i.e., labial face with concave profile just below the crest, convex lower down; lingual face slightly more developed than the labial, with convex profile in its upper part and a concave profile in its mid-lower region) that justify the recognition of a second species within the genus, i.e., <i>A. crassicaudata</i>. This taxon also shows a unique combination of features (e.g., pectoral disc large and rhomboid; tail short, 44–52% of total length; ca. 238 vertebral centra; distal segment of propterygia located between mouth and antorbital cartilage; mesopterygium single, not fused to radials; 100–117 pectoral radials; 15–17 pelvic-fin radials; elongated caudal fin of aplesodic type) that supports its sister-group relationship with the living urolophids <i>Urolophus</i> and <i>Trygonoptera</i>. <i>Arechia</i> was a typical inhabitant of the near coastal and warm habitats that characterize the Monte Postale paleoenvironment.
