Redescription of the cranial skeleton of the Early Devonian (Emsian) sarcopterygian Durialepis edentatus Otto, 2007 (Dipnomorpha; Porolepiformes)
<p>Porolepiforms represent a clade of Devonian stem lungfishes, divided into the cosmine-bearing and likely paraphyletic 'Porolepidae' (e.g., <em>Porolepis</em>, <em>Heimenia</em>) and the cosmine-free and stratigraphically younger Holoptychiidae (e.g., <em>Holoptychius</em>, <em>Glyptolepis</em>, <em>Laccognathus</em>). Data on the dermoskeleton are available for both groups, but are more limited for 'porolepids'. Here we present new information on the 'porolepid' <em>Durialepis edentatus</em> from the Emsian (Early Devonian) of Germany based on micro-CT scanning. The material comprises an articulated skull of a single three-dimensionally preserved individual. The arrangement of the cheekbones of <em>Durialepis edentatus</em> recalls that of <em>Porolepis brevis</em>, with the occurrence of two subsidiary squamosals. However, the parieto-ethmoidal and postparietal shields are roughly equal in size, a condition similar to that of <em>Glyptolepis groenlandica</em> and intermediate between <em>Porolepis brevis</em> and holoptychiids. A large parasymphysial tooth plate displays five tooth rows with three large tusks in the median row, another intermediate arrangement between the primitive condition of <em>Porolepis</em> sp. (eight rows) and holoptychiids (five or fewer rows). Remarkably among porolepiforms, this dental plate is perfectly symmetrical. Despite the occurrence of cosmine and rhombic scales, the combination of traits displayed in <em>Durialepis</em> deviates from <em>Porolepis</em> in several ways, reflecting features shared with holoptychiids to the exclusion of other 'porolepids'. <em>Durialepis edentatus</em> is thus a key addition to our knowledge of 'porolepid' anatomy. Because <em>Durialepis edentatus</em> preserves much of the cranial and postcranial skeleton in a single individual, it represents a suitable early dipnomorph representative for inclusion in phylogenetic analyses on sarcopterygians and early osteichthyans.</p>
Ediacaran metazoan fossils with siliceous skeletons from the Digermulen Peninsula of Arctic Norway – Supplementary Data
<p><span>In this study, a new assemblage of Ediacaran metazoan fossils is reported from the basal Stáhpogieddi Formation on the Digermulen Peninsula of Arctic Norway, including <i>Anulitubus</i> n. gen. Moczydłowska in Moczydłowska et al., <i>Anulitubus formosus</i> n. gen. n. sp. Moczydłowska in Moczydłowska et al., <i>Coniculus</i> n. gen. Moczydłowska in Moczydłowska et al., <i>Coniculus elegantis</i> n. gen. n. sp. Moczydłowska in Moczydłowska et al., <i>Fistula</i> n. gen. Moczydłowska in Moczydłowska et al., <i>Fistula crenulata</i> n. gen. n. sp. Moczydłowska in Moczydłowska et al. The specimens are three-dimensionally preserved and include tubular and conical skeletons that are morphologically distinguished by their body wall constructions, radial symmetry, polarity, segmentation, and annulation. The skeletons are interpreted to be biomineralized by primary silica based on computed micro-tomographic, petrographic, geochemical and spectroscopic evidence of originally rigid body wall with layers of constant thicknesses, composed of opal, microcrystalline quartz and admixture of carbonaceous material, which differ from the host sediment mineralogy and do not show replacement or encrustation. The fossil-bearing interval immediately overlies strata of Gaskiers age and can be bracketed within 580–541 Ma, but it is estimated to be ~575 Ma on the basis of averaged sedimentation rates and biostratigraphic correlations with Ediacaran biota found in up-section deposits of ~558–555 Ma. Future new findings of such fossils in different preservation modes and further multi-collector inductively coupled plasma mass spectrometry, which shows the silicon fractionation and trace its biogenic origin vs inorganic mineralization, may corroborate the interpretation of biogenic silicification of these earliest skeletal fossils.</span></p>
Differing limb functions and their potential influence upon the diversification of the mustelid hindlimb skeleton
<p>Though form-function relationships of the mammalian locomotor system have been investigated for over a century, recent models of trait evolution have hitherto been seldom used to identify likely evolutionary processes underlying the locomotor system's morphological diversity. Using mustelids, an ecologically diverse carnivoran lineage, I investigated whether variation in hindlimb skeletal morphology functionally coincides with climbing, digging, swimming, and generalized locomotor habits by using 15 linear traits of the femur, tibia, fibula, calcaneum, and metatarsal III across 44 species in a principal components analysis. I subsequently fit different models of Brownian motion and adaptive trait diversification individually to each trait. Climbing, digging, and swimming mustelids occupy distinct regions of phenotypic space characterized by differences in bone robustness. Models of adaptive and neutral evolution are, respectively, the best fits for long bone lengths and muscle in-levers, suggesting that different kinds of traits may be associated with different evolutionary processes. However, simulations based upon models of best fit reveal low statistical power to rank the models. Though differences in mustelid hindlimb skeletal morphology appear to coincide with locomotor habits, further study, with sampling expanded beyond Mustelidae, is necessary to better understand to what degree adaptive evolution shapes morphological diversity of the locomotor system.</p>
