1. Descripción del postcráneo de Rhipidomys austrinus y Graomys griseoflavus (Rodentia, Cricetidae, Sigmodontinae)
We described the postcranial skeleton of two species of sigmodontine rodents, Rhipidomys austrinus Thomas, 1921 and Graomys griseoflavus (Waterhouse, 1837). Each structure of the postcranial skeleton is here described in details of shape, size, surface, and orientation. The skeletal anatomy of these two species shows morphological characters associated with

2. O esqueleto pós-craniano de Exaeretodon Riograndensis Abdala et al. (Cynodontia, Traversodontidae), Triássico do Brasil. / The postcranial skeleton of exaeretodon riograndensis abdala et al. (Cynodontia, traversodontidae), triassic of Brazil
Pela primeira vez, elementos pós-cranianos de Exaeretodon riograndensis, um cinodonte traversodontídeo da Cenozona de Rhynchosauria da Formação Santa Maria, Neotriássico do sul do Brasil, são descritos e comparados com E. frenguellii e outros cinodontes não-mamalianos. O material inclui parte da coluna vertebral, radio, ulna e elementos da cintura pé

3. A new species of Baurusuchus (Crocodyliformes, Mesoeucrocodylia) from the Upper Cretaceous of Brazil, with the first complete postcranial skeleton described for the family Baurusuchidae
O presente trabalho descreve uma espécie nova de Baurusuchidae proveniente de sedimentos do Cretáceo Superior da Bacia Bauru, no Estado de São Paulo, fornecendo a primeira descrição de um esqueleto pós-craniano completo para a família. Muitas características pós-cranianas da nova espécie estão presentes em outros táxons de Notosuchia gondwânicos

4. Descrição morfológica e posicionamento filogenético de um Baurusuchidae (Crocodyliformes, Mesoeucrocodylia) do Cretáceo Superior da Bacia Bauru, região de General Salgado (SP). / Morphological description and phylogenetical position of a Baurusuchidae (Crocodyliformes, Mesoeucrocodylia) from Late Cretaceous of Bauru Basin, General Salgado area (São Paulo state)
The area of General Salgado (Adamantina Formation, Bauru Basin) is extremely rich in vertebrate fossils. This richeness is evident with the presence of several records of Cretaceous crocodiliforms. Among them, an articulated skeleton of a new Baurusuchidae was found, composed by parts of the cranium and a practically complete post-cranium. Characters that pl

6. The development of pneumatisation in the postcranial skeleton of the domestic fowl.
The development of pneumatisation in the postcranial skeleton has been investigated in a flock of Golden Comet pullets from hatching to 182 days posthatching. The timing of development of pneumatisation in the vertebral column, vertebral ribs, sternum and humerus has been demonstrated. No pneumatisation was encountered in the sternal ribs, os coxae or coraco

7. Phylogenetic and functional affinities of Babakotia (primates), a fossil lemur from northern Madagascar.
Recent paleontological expeditions to the Ankarana range of northern Madagascar have recovered the partial remains of four individuals of a newly recognized extinct lemur, Babakotia radofilai. Craniodental and postcranial material serve to identify Babakotia as a member of the palaeopropithecids (also including the extinct genera Palaeopropithecus, Archaeoin

8. The distribution of pneumatisation in the skeleton of the adult domestic fowl.
The occurrence of pneumatisation in the skull of the adult domestic fowl was investigated in eight birds by gross and histological examination. It was found to occur regularly throughout the neurocranium and in the quadrate and variably in the mandible, but to be absent in the facial skeleton. Close agreement was found between gross and histological examinat

9. A new extinct primate among the Pleistocene megafauna of Bahia, Brazil.
A nearly complete skeleton of a robust-bodied New World monkey that resembles living spider monkeys was recovered from undisturbed Pleistocene deposits in the Brazilian state of Bahia. The skeleton displays the highly specialized postcranial pattern typical of spider and woolly spider monkeys and shares cranial similarities to the spider monkey exclusively.

10. Sexual dimorphism in Australopithecus afarensis was similar to that of modern humans
The substantial fossil record for Australopithecus afarensis includes both an adult partial skeleton [Afar Locality (A.L.) 288-1, “Lucy”] and a large simultaneous death assemblage (A.L. 333). Here we optimize data derived from both to more accurately estimate skeletal size dimorphism. Postcranial ratios derived from A.L. 288-1 enable a significant i

11. Visualizing the lateral somitic frontier in the Prx1Cre transgenic mouse
Changes in the organization of the musculoskeletal system have accounted for many evolutionary adaptations in the vertebrate body plan. The musculoskeletal system develops from two mesodermal populations: somitic mesoderm gives rise to the axial skeleton and all of the skeletal muscle of the body, and lateral plate mesoderm gives rise to the appendicular ske

12. Skeletal and dental morphology supports diphyletic origin of baboons and mandrills
Numerous biomolecular studies from the past 20 years have indicated that the large African monkeys Papio, Theropithecus, and Mandrillus have a diphyletic relationship with different species groups of mangabeys. According to the results of these studies, mandrills and drills (Mandrillus) are most closely related to the torquatus–galeritus group of mangabeys
