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>

Figure 33. Phidippus adonis, Morelos. Observe that many species have the foreleg pattern repeated on the following legs. This is particularly noticeable when the male raises the forelegs, as the second leg pair are shifted forward to support him. The four leg pattern formed by the first and second pair of legs is quite striking when the pattern is complex, and it seems likely that the second pair of legs augments the display when the forelegs are raised, perhaps during courtship (Figure 30), but also during threat displays (Figure 31, with forelegs raised; Figures 32-33 taken just after forelegs were lowered from full threat display). Note also that in P. arizonensis and P. cruentus (see previous figure plate), this is not true, as at least the femora of the forelegs are unique, unlike the succeeding leg pairs.

Lee's Ferry – Grand Canyon, Arizona
Lee's Ferry is the beginning of the Grand Canyon National Park, and the place where nearly all river trips launch from. Originally a ferry point across the river started by Mormon pioneer John D. Lee in the 1870s, many a young couple would cross this point and continue on to St. George, Utah to be married. The aptly-named "Honeymoon Trail" crosses this point and up into the red rocks of the Moenkopi, where wagon ruts from the 1800s can still be seen today. At Lee's Ferry you can go left into Glen Canyon National Recreation Area for nearly 15 miles before the Glen Canyon Dam at Lake Powell, or go right for 277 miles to the end of the Grand Canyon at Lake Mead. The brown water you see entering the Colorado River just below the boat ramp is a flash flood of the Paria River, starting in Bryce Canyon National Park in Utah. These are famous gold water trout waters and a popular fishing spot for anglers. Source: Objaverse 1.0 / Sketchfab
Woody plant diversity before and after the Horseshoe Two Fire in the Chiricahua Mountains, Arizona, USA
<p>Aim: Drastic changes in fire regimes are altering plant communities, inspiring ecologists to better understand the relationship between fire and plant species diversity. We examined the impact of a 90,000-ha wildfire on woody plant species diversity in an arid mountain range in southern Arizona, USA. We tested recent fire-diversity hypotheses by addressing the impacts of fire severity, fire variability, historical fire regimes, and topography on diversity.</p> <p>Location: Chiricahua National Monument, Chiricahua Mountains, Arizona. USA., part of the Sky Islands of the US-Mexico borderlands.</p> <p>Taxon: Woody plant species.</p> <p>Methods: We sampled woody plant diversity in 138 plots before (2002-2003) and after (2017-2018) the 2011 Horseshoe Two Fire in three vegetation types and across fire severity and topographic gradients. We calculated gamma, alpha, and beta diversity and examined changes over time in burned vs. unburned plots and the shapes of the relationships of diversity with fire severity and topography.</p> <p>Results: Alpha species richness declined and beta and gamma diversity increased in burned but not unburned plots. Fire-induced enhancement of gamma diversity was confined to low fire severity plots. Alpha diversity did not exhibit a clear continuous relationship with fire severity. Beta diversity was enhanced by fire severity variation among plots and increased with fire severity up to very high severity, where it declined slightly.</p> <p>Main Conclusions: The results reject the intermediate disturbance hypothesis for alpha diversity but weakly support it for gamma diversity. Spatial variation in fire severity promoted variation among plant assemblages, supporting the pyrodiversity hypothesis. Long-term drought probably amplified fire-driven diversity changes. Despite the apparent benign impact of the fire on diversity, the replacement of two large conifer species with a suite of drought-tolerant shrubs signals the potential loss of functional diversity, a pattern that may warrant restoration efforts to retain these important compositional elements.</p>
