Caimanines are crocodylians currently restricted to South and Central America the oldest members from lower Palaeocene localities of Salamanca Formation (Chubut Province, Argentina). We report here a new caimanine this same unit represented by skull roof partial braincase. Its phylogenetic relationships were explored in cladistic analysis using standard characters morphogeometric two-dimensional configuration roof. The results used for an event-based supermodel quantitative...
Abstract Melanosuchus niger (Crocodylia, Alligatoroidea) is one of the six living caimanine species widely distributed throughout Amazon River basin today. Although there only extant , fossil material assigned to this genus, represented by M. fisheri has been reported from late Miocene in South America. However, validity taxon questioned and a recent investigation indicates that referred specimen (MCZ 4336) actually belongs Globidentosuchus brachyrostris while those diagnostic characters...
Here we present a comparative anatomical study of large late Miocene alligatorids Argentina (Ituzaingó Formation), in which analyse their taxonomy, morphological disparity, and phylogenetic relationships. 'Caiman lutescens' Caiman gasparinae are two giant Argentinean caimanines that assigned to the genus Caiman. was originally described based on size several isolated cranial postcranial elements. In this consider lectotype 'C. lutescens', an articulated left premaxilla maxilla (MACN-Pv...
Melanosuchus niger Spix is distributed throughout the Amazon River basin today. The extinct fisheri Medina from late Miocene of Venezuela was erected based on two almost complete, but heavily deformed skulls (the holotype MCNC 243 and referred specimen MCZ 4336), which show morphological differences each other. comparison indicates that only can be to Gray. We propose 4336 a representative caimanine Globidentosuchus brachyrostris Scheyer, Aguilera, Delfino, Fortier, Carlini, Sánchez,...
Abstract The homology and evolution of the archosaur ankle is a controversial topic that has been deeply studied using evidence from both extinct extant taxa. In early stem archosaurs, astragalus calcaneum form ancestral proximal tarsus single ossification composes centrale series. more recent incorporated to row tarsals laterally contacting astragalus. This bone subsequently lost as an independent before last common ancestor birds crocodilians, but evolutionary fate this element remains...
Liver fibrosis results from cycles of liver damage and scar formation. We herein aimed at analysing neural crest cells and/or bone marrow stromal contribution to the liver.Two one hepatectomy model were applied on double-transgenic loxP-Cre mouse lines.Increased numbers glia with more complex processes found in fibrotic livers. During embryonic development, only few traced marrow, a minor fraction mice different reporter strains analysed: therefore, origin such is doubtful. In liver,...
Abstract The lower jaw of early tetrapods is composed several intramembranous ossifications. However, a tendency toward the independent reduction number bones has been observed in mandible mammals, lepidosaurs, turtles, crocodiles, and birds. Regarding archosaurs, coronoid prearticular are interpreted to be lost during evolution stem‐birds stem‐crocodiles, respectively, but homology post‐dentary retained living pseudosuchians remains unclear. Here, we combine paleontological embryological...
Shape ontogenetic changes of the lower jaw in crocodylians are poorly understood. In order to answer some questions related inter- and intraspecific morphological variation mandible two extant Caiman species, we performed a three-dimensional geometric morphometric approach. For this purpose, used landmarks semilandmarks on mandibular series 48 15 post-hatching specimens C. yacare latirostris, respectively. We have also examined relationship between these anatomical transformations shifts...
Abstract Little is known about the embryonic development and variation of chondrocranium in Crocodylia there are no works on any Caiman species. Due to importance cranial features systematics this clade, investigating skull stages essential. In study, we present for first time cartilaginous two extant Anatomical descriptions latirostris yacare were made, paying special attention their inter‐ intraspecific variation. For purpose, pre‐hatching ontogenetic series these caiman species prepared...
The preparation and characterization of borated zirconia calcined at 320 °C was studied. prepared using zirconyl chloride as precursor ammonium hydroxide precipitating agent. Pore-forming agents during synthesis were added, specifically glucose or polyethylene glycol (PEG) different molecular weight. After drying, an aqueous solution boric acid added to the zirconia. Zirconias without addition also prepared. specific surface area zirconias is higher than those samples boron. PEG led a mean...
The reactivities of calcined magnesites for industrial use and magnesium oxides prepared from basic carbonate were assessed by using potentiometry to monitor pH changes in aqueous suspensions following step wise acid additions. results compared with those obtained calorimetric measurements performed during formation oxychloride cement. quality cements made these materials was checked compressive strength determinations found correlate well the experimental reactivities.
About one in six couples experience fertility problems, and male infertility accounts for about half of these cases. Spermatogenesis originates from a small pool spermatogonial stem cells (SSCs), which are interest the treatment but remain poorly characterised humans. Using multiparametric spectral flow cytometric analysis with 16-colours (16-C) panel cell markers, we identify novel markers SSCs provide insights into unravelling resolving heterogeneity human cells. This 16-C allowed...
Adsorption isotherms of Zn2+ and/or Co2+ ions on an 8 wt.% MoO3/alumina catalyst have been obtained. The Langmuir parameters derived from regression the results indicate that preimpregnation alumina with molybdate solutions notably decreased adsorption and ions. In containing both ions, saturation capacity was practically unaffected, while significantly reduced owing to higher intrinsic affinity for sites. occurs two type sites, i. e. those which are loosely strongly bound; latter is not...
