The oldest known amniotic embryos suggest viviparity in mesosaurs
TLDR
The finds of exceptional, well-preserved amniotic mesosaur embryos from the Early Permian of Uruguay and Brazil provide the earliest direct evidence of reproductive biology in Paleozoic amniotes and the earliest known case of viviparity.
Optimal swimming speed estimates in the Early Permian mesosaurid Mesosaurus tenuidens (Gervais 1865) from Uruguay
TLDR
Results of the first biomechanical study about optimal swimming capabilities in Mesosaurus tenuidens are presented, which suggest a fairly low optimal swimming speed for mesosaurids, which is consistent with capture of fairly slow prey like pygocephalomorphs, possibly by filter-feeding, rather than by active pursuit of fast prey.
Human growth hormone treatment in prepubertal children with achondroplasia.
TLDR
It is shown that r-hGH can safely increase short-term growth velocity in some but not all prepubertal children with achondroplasia, and the individual variability in the response to the GH treatment is confirmed.
Early archosauromorph remains from the Permo-Triassic Buena Vista Formation of north-eastern Uruguay
TLDR
Cranial and postcranial bones from the Permo-Triassic Buena Vista Formation of northeastern Uruguay are described that contribute to increase the meagre early archosauromorph record from South America and reinforces the broad palaeobiogeographic distribution of ‘proterosuchid grade’ diapsid beds worldwide.
Conservation status assessment of the amphibians and reptiles of Uruguay
TLDR
The use of these results as an additional criterion in the definition of protected areas in Uruguay will contribute towards the conservation of the aforementioned threatened species and their associated ecosystems.
Preliminary Biochemical and Venomic Characterization of the Venom of Phalotris lemniscatus (Serpentes, Colubridae).
TLDR
The results indicate that the venom of P. lemniscatus contains hemotoxic activities and components that resemble those found in Viperidae (Bothrops) snakes and that can induce a clinically relevant accident.
Was Mesosaurus a Fully Aquatic Reptile?
TLDR
It is found that the variation of the vertebral centrum length along the axial skeleton of Mesosaurus tenuidens fits better with a semi-aquatic morphometric pattern, as shown by comparisons with other extinct and extant taxa.
The ontogenetic transformation of the mesosaurid tarsus: a contribution to the origin of the primitive amniotic astragalus
TLDR
The structure of the amniotic tarsus, including the configuration of the proximal series formed by the astragalus and the calcaneum, could have been established well before the first recognized amniote walked on Earth.
Conservation planning in Uruguay based on small felids (Leopardus spp.) as umbrella species
ABSTRACT Felids biogeographic patterns in Uruguay are poorly understood despite the importance of fringe populations of species in conservation. We determined suitability areas, analyzed species…
A NEW GENUS AND SPECIES OF OPISTHOGONIMID (DIGENEA) OF LIOPHIS ANOMALUS (SERPENTES: COLUBRIDAE) FROM URUGUAY
During a study on the helminth fauna of Liophis anomalus specimens deposited in the Reptile Collection of the Sección Zoología Vertebrados, Facultad de Ciencias, Uruguay, a new genus of…
