Fig. 8 in A new genus of Norian involutinid foraminifers: Its morphological, biostratigraphic, and evolutionary significance
Fig. 8. Sketch showing the theoretical evolutionary steps of the hypothetic Aulotortus–Triasina lineage.
Fig. 7 in A new genus of Norian involutinid foraminifers: Its morphological, biostratigraphic, and evolutionary significance
Fig. 7. Tubular chamber section concept in Involutinidae. Aulotortus: tubular chamber simple, without internal structures; Aulosina gen. nov.: tubular chamber lumen constricted by strenghtenings; Triasina: tubular chamber supported by inner−pillars.

Data from: Potentials of closed contour analysis in species differentiation and holotype designation: a case study on lower Norian (Upper Triassic) conodonts
<p><span>Geometric morphometric approaches become increasingly applied in the fields of biology and paleontology. Taxonomy is a good example, where a long-standing intention of scientists is to eliminate subjectivity as much as possible. In the case of biostratigraphically important conodont elements, the application of such methods is not widespread. Indeed, only a handful of studies attempted to deal with the morphological variance of conodont elements from this aspect. The detailed description of five lower Norian (Upper Triassic) taxa (<em>Ancyrogondolella quadrata, A. rigoi, A. triangularis, A. uniformis</em> and <em>Metapolygnathus mazzai</em>) is presented here based on landmarks and Fourier analysis of the P1 element and keel outlines. Both methods led to similar outcomes regarding taxonomic differentiation and exposing shape variability. Consensus shapes were generated to objectively reveal the typical contour shape of each taxon, which allowed their comparison with each other, and with the members of their respective sample population including the holotypes. The results pointed out that the holotype of a taxon is generally not an average representative, but rather a peripheral form with well-separable morphological characteristics. <em>Ancyrogondolella quadrata</em> and <em>A. rigoi</em> turned out to represent a morphological continuum with ample transitional forms between these two end-members that may cause bias in their biostratigraphic applicability; however, their combined shape variance seems to be too large for uniting them into a single species. Given the results that may be too subtle to realize based solely on qualitative observations, future taxonomic studies and type material designation could greatly benefit from the application of similar methodologies.</span></p>

Data from: Puercosuchus traverorum n. gen. and sp.: a new malerisaurine azendohsaurid (Archosauromorpha: Allokotosauria) from two monodominant bonebeds in the Chinle Formation (Upper Triassic, Norian) of Arizona
<p><span><span>Non-archosaur archosauromorphs are a paraphyletic group of diapsid reptiles that are important members of global Middle Triassic and Late Triassic continental ecosystems. Included in this group are the azendohsaurids, a clade of allokotosaurians (kuehneosaurids and Azendohsauridae + Trilophosauridae) that retain the plesiomorphic archosauromorph postcranial body plan but have evolved disparate cranial features that converge on later dinosaurian anatomy, including sauropodomorph-like marginal dentition and ceratopsian-like postorbital horns. Here we describe a new malerisaurine azendohsaurid from two monodominant bonebeds in the Blue Mesa Member, Chinle Formation (Late Triassic, ~218</span><span>–</span><span>220 Ma); the first occurs at Petrified Forest National Park and preserves a minimum of eight individuals of varying sizes, and the second occurs near St. Johns, Arizona. <em>Puercosuchus traverorum</em> n. gen. and sp. is a carnivorous malerisaurine that is closely related to <em>Malerisaurus robinsonae</em> from the Maleri Formation of India and to <em>Malerisaurus langstoni</em> from the Dockum Group of western Texas. Dentigerous elements from <em>Puercosuchus traverorum</em> confirm that some Late Triassic tooth morphotypes thought to represent early dinosaurs cannot be differentiated from, and likely pertain to, <em>Puercosuchus</em>-like malerisaurine taxa. These bonebeds from northern Arizona support the hypothesis that non-archosauriform archosauromorphs were locally diverse near the middle of the Norian and experienced an extinction event prior to the end-Triassic mass extinction coincidental with the Adamanian-Revueltian boundary recognized at Petrified Forest National Park. The relatively late age of this early-diverging taxon (Norian) suggests that the diversity of azendohsaurids is underrepresented in the Middle Triassic and Late Triassic fossil records around the world.</span></span></p>
