“…The projection of the parasphenoid plate over the most caudal part of the rostrum parasphenoid was similar to that described for Ciconiiformes (FERREIR;DONATELLI, 2005) and for individuals of the family Nyctibiidae (Caprimulgiformes) (COSTA;DONATELLI, 2009).…”

Obtaining craniometric data is key to establishing parameters that can help in the anatomic identification and understanding of species. The aim of the present study was to establish the craniometric data and describe the main skull bones and structures of Amazona aestiva, which has become common in veterinary clinics, originated from the legalized purchase or trafficking of animals. A total of 20 adult specimens were used, donated for studies by the Paraíba Wild Animal Screening Center (Centro de Triagem de Animais Silvestres da Paraíba (CETAS-PB)/IBAMA-PB, Brazil. The skulls were dissected and macerated with water. First were identified the frontal, maxilla, mandible, nasal, jugal and quadrate bones that served as a base to identify other bone structures that were then compared with the skull of other bird species already described in the literature, especially psitacids. Values were obtained by measuring with a digital pachymeter, and the maximum skull length was 63.0 mm, the maximum width 33.0 mm and the rhamphotheca was 33.8 mm long. No significant differences were observed between males and females and well developed cranial kinesis was a remarkable characteristic of the species. The data obtained serve as a base to identify and characterize the species. These data can also aid in the clinic, imaging and veterinary surgery.

“…Character descriptions are provided in the Appendix and the data matrix has been made publicly available on Morphobank (O'Leary and Kaufman, 2012) under Project 3614 see text footnote 1. In addition to the methods outlined in Musser and Cracraft (2019) and creation of most characters from direct observation of avian skeletons, characters from several previously published morphological datasets (Strauch, 1978;Cracraft and Clarke, 2001;Ferreira and Reginaldo, 2005;Livezey and Zusi, 2006;Mayr, 2008Mayr, , 2013, especially those that focused on Charadriiformes (Livezey, 2009(Livezey, , 2010Mayr, 2011b), were evaluated for use in this iteration of the dataset. Specimen numbers for examined taxa are presented in Table 1.…”

The stem lineage relationships and early phenotypic evolution of Charadriiformes (shorebirds) and Gruiformes (rails, cranes, and allies) remain unresolved. It is still debated whether these clades are sister-taxa. New phylogenetic analyses incorporating Paleogene fossils have the potential to reveal the evolutionary connections of these two speciose and evolutionarily critical neoavian subclades. Although Gruiformes have a rich Paleogene fossil record, most of these fossils have not been robustly placed. The Paleogene fossil record of Charadriiformes is scarce and largely consists of fragmentary single elements. Only one proposed Eocene charadriiform-like taxon, Scandiavis mikkelseni of Denmark, is represented by a partial skeleton. Here, we describe a new species from the early Eocene Green River Formation of North America comprising a partial skeleton and feather remains. Because the skeleton lacks the pectoral girdle and forelimbs as in S. mikkelseni, only features of the skull, axial skeleton, and hind limb are available to resolve the phylogenetic placement of this taxon. These anatomical subregions initially showed features seen in Charadriiformes and Gruiformes. To assess placement of this taxon, we use a matrix consisting of 693 morphological characters and 60 taxa, including S. mikkelseni and the oldest known charadriiform taxa represented by single elements. These more fragmentary records comprise two distal humeri from the earliest Eocene Naranbulag Formation of Mongolia and the early Eocene Nanjemoy Formation of Virginia. Our phylogenetic analyses recover the new taxon and S. mikkelseni alternatively as a charadriiform or as a stem-gruiform; placement is contingent upon enforced relationships for major neoavian subclades recovered by recent molecular-based phylogenies. Specifically, when constraint trees based on results that do not recover Charadriiformes and Gruiformes as sister-taxa are used, the new taxon and S. mikkelseni are recovered within stem Gruiformes. Both Paleogene fossil humeri are consistently recovered within crown Charadriiformes. If placement of these humeri or the new taxon as charadriiforms are correct, this may indicate that recent divergence time analyses have underestimated the crown age of another major crown avian subclade; however, more complete sampling of these taxa is necessary, especially of more complete specimens with pectoral elements.

Traditional wisdom holds that biotic recovery from the end-Permian extinction was slow and gradual, and was not complete until the Middle Triassic. Here, we report that the evolution of marine predator feeding guilds, and their trophic structure, proceeded faster. Marine reptile lineages with unique feeding adaptations emerged during the Early Triassic (about 248 million years ago), including the enigmatic Hupehsuchus that possessed an unusually slender mandible. A new specimen of this genus reveals a well-preserved palate and mandible, which suggest that it was a rare lunge feeder as also occurs in rorqual whales and pelicans. The diversity of feeding strategies among Triassic marine tetrapods reached their peak in the Early Triassic, soon after their first appearance in the fossil record. The diet of these early marine tetrapods most likely included soft-bodied animals that are not preserved as fossils. Early marine tetrapods most likely introduced a new trophic mechanism to redistribute nutrients to the top 10 m of the sea, where the primary productivity is highest. Therefore, a simple recovery to a Permian-like trophic structure does not explain the biotic changes seen after the Early Triassic.
