“…barberenai was investigated based on the taxon-character matrix of Bronzati et al . [36], which incorporates previous modifications by several authors [37–44] to the Yates [45] original dataset. The “Oxford braincase” was excluded from the data-matrix and, after Bronzati et al .…”

“…In its traditional understanding, it includes various neotheropods [7], the entire diversity of Herrerasauria [8], and several other possible members of the theropod line [1, 3, 9–10]. However, most recent hypotheses suggest that the majority of known Triassic taxa are nested within the sauropodomorph branch, including a plethora of Norian-Rhaetian forms [11], plus a handful of Carnian taxa from South America [12]. Despite this richness, the first radiation of Sauropodomorpha is still poorly known, partially due to uncertainties regarding the relationships and alpha taxonomy of those same Carnian taxa [13].…”

Sauropodomorphs are the most abundant and diverse clade of Triassic dinosaurs, but the taxonomy of their earliest (Carnian) representatives is still poorly understood. One such taxon is Pampadromaeus barberenai , represented by a nearly complete disarticulated skeleton recovered from the upper part of the Santa Maria Formation of Rio Grande do Sul, Brazil. Here, the osteology of Pam . barberenai is fully described for the first time. Detailed comparisons with other Carnian sauropodomorphs reveal a unique anatomy, corroborating its status as a valid species. Potential autapomorphies of Pam . barberenai can be seen in the articulation of the sacral zygapophyses, the length of the pectoral epipodium, the shape of the distal articulation of the femur and the proximal articulation of metatarsal 1. A novel phylogenetic study shows that relationships among the Carnian sauropodomorphs are poorly constrained, possibly because they belong to a “zone of variability”, where homoplasy abounds. Yet, there is some evidence that Pam . barberenai may nest within Saturnaliidae, along with Saturnalia tupiniquim and Chromogisaurus novasi , which represents the sister group to the larger sauropodomorphs, i.e. Bagualosauria.

The type specimens of 15 nominal species of Aplysiida (Gastropoda, Heterobranchia) at the Academy of Natural Sciences of Philadelphia are listed and their primary types are illustrated. Type materials described by the following authors are present: Henry A. Pilsbry (9 names), Angelo Heilprin (2), Charles N. E. Eliot (1), William H. Pease (2) and Elizabeth J. Letson (1). Some taxonomic notes are provided. Aplysiaperviridis (Pilsbry, 1895), comb. nov., Aplysiapilsbryi (Letson, 1898), and Aplysiapulmonica Gould, 1852 are reinstated as valid.
