A very large pterosaur (MN 6594-V) from the Romualdo Formation (Aptian/Albian), Santana Group, Araripe Basin, is described. The specimen referred to Tropeognathus cf. T. mesembrinus mainly due presence of a low and blunt frontoparietal crest, comparatively number teeth inclined dorsal part occipital region. Two distinct wingspan measurements for pterosaurs are introduced: maximized (maxws), which essentially consists doubling addition all wing elements length scapula or coracoid (the smaller...
Fossil vertebrates from Antarctica are considerably rare, hampering our understanding of the evolutionary history biota that continent. For several austral summers, PALEOANTAR project has been carrying out fieldwork in Antarctic Peninsula search for fossils, particularly Cretaceous vertebrates. Among specimens recovered so far two bones referable to Pterosauria, more specifically Pterodacyloidea, first volant reptiles be fully described. MN 7800-V (part and counterpart) was a moraine at...
A remarkably well-preserved, almost complete and articulated new specimen (GP/2E 9266) of Tupandactylus navigans is here described for the Early Cretaceous Crato Formation Brazil. The comprises an skeleton, preserving both skull post-cranium, associated with remarkable preservation soft tissues, which makes it most tapejarid known thus far. CT-Scanning was performed to allow assessment bones still covered by sediment. can be assigned Tupa . due its vertical supra-premaxillary bony process...

The counterpart of a previously described non-pterodactyloid pterosaur with an egg revealed the presence second inside body cavity this gravid female. It clearly shows that pterosaurs had two functional oviducts and demonstrates reduction one oviduct was not prerequisite for developing powered flight, at least in group. Compositional analysis suggests lack hard external layer calcium carbonate. Histological sections femur medullary bone further demonstrate reached reproductive maturity...
Crocodyliformes have a well-known worldwilde fossil record, revealing high diversity of morphological traits, habits and being abundant in their paleofaunas. Such abundance the record is remarkable tetrapod continental sequences Bauru Group (Brazil), Cretaceous South America. Here we describe analyse three specimens from Group, assigned to poorly understood crocodyliform clade: Itasuchidae. Their similarity them as Pepesuchus (from Turonian / Coniacian Araçatuba Formation), Itasuchus cf....
New isolated pterodactyloid bones from the Toolebuc Formation are described. The first one consists of a complete wing metacarpal 212 mm long, representing an individual with estimated span 4 m. Small depressions on anterior surface present and represent tooth marks showing that this specimen was subjected to scavenging prior fossilization. other bone three-dimensionally preserved cervical vertebra lacking most neural arch. specimens clearly referable derived pterosaur clade...
Thalassodromeus sethi (Pterodactyloidea, Tapejaridae, Thalassodrominae) is a unique pterosaur from the Romualdo Formation, Araripe Basin (Early Cretaceous, Albian). A large sagittal cranial crest (the largest known ossified of any pterosaur) and unusual toothless bladed jaws constitute some its outstanding anatomical features. Its holotype (DGM 1476-R, almost complete skull mandible in three dimensions) represents one skulls ever found. Here, we provide detailed osteological redescription...
Flying reptiles from Australia are very rare, represented mostly by isolated bones coming the Early Cretaceous (Albian) Toolebuc Formation, which crops out in western Queensland. Among first pterosaur specimens discovered this deposit is a mandibular symphysis that some authors thought to have particular affinity species found Cambridge Greensand (Cenomanian) of England. It was further referred as member or closely related one genera Ornithocheirus, Lonchodectes Anhanguera. Here we...
The pterosaur fossil record from Africa is exceedingly scarce and one of the least known for any continental land mass. specimens here described are housed at Naturkundemuseum Humboldt University consist two cervical vertebrae, a coracoid wing metacarpal recovered Upper Jurassic Tendaguru Formation, Tanzania. Due to general morphology absence lateral pneumatic foramen in both as well presence longitudinal depression, not previously reported pterosaurs, we consider these representatives new...
Pterosaurs consist of an extinct group flying reptiles that show short- and long-tailed species. Among those are the anurognathids whose phylogenetic position has been considered quite controversial. So far, there about 10 described specimens from Anurognathidae, which only a few preservation caudal elements. Here, we report new anurognathid specimen (IVPP V16728) Mutoudeng, Qinglong, Hebei, China shows most complete tail this non-pterodactyloid clade. The preserved part at least 20...
The frog clade Neobatrachia or “advanced frogs” represents more than 95% of the diversity within Anura. neobatrachian fossil record is incomplete due to small size and fragile nature their bones but provides some clues on time rate current diversification modern-day amphibians. Crato Formation (Aptian) northeastern Brazil known for presence of, at least, five species fossils. Herein, we describe a well-preserved that new taxon from (Cretaceous) in Araripe Basin, Brazil, perform phylogenetic...
Jurassic African pterosaur remains are exceptionally rare and only known from the Tendaguru deposits, Upper Jurassic, Tanzania. Here we describe two right humeri of pterosaurs Humboldt University Berlin: specimens MB.R. 2828 (cast MN 6661-V) 2833 6666-V). consists a three-dimensionally preserved proximal portion. The combination morphological features deltopectoral crest not observed in other suggests that this specimen belongs to new dsungaripteroid taxon. is nearly complete, because long...
The stance of pterosaurs on land is traditionally a controversial question. Here, we show that like Anhanguera piscator were quadrupeds. An osteological model A. was three-dimensionally built in digital space. reconstructed muscles its pelvic girdle then placed their points origin and insertion to allow the biomechanical calculations find most efficient be performed. hindlimb readjustment (i.e. repositioning according achieved results) led counterclockwise displacement at 10°, which means...
Abstract The reconstruction of jaw muscles is critical in establishing potential cranial functions; however, myological studies extinct groups that have no descendants are difficult to perform and test. This particularly true for pterosaurs, a group flying reptiles present plethora morphologies, suggesting different functions feeding habits. Here we first attempt reconstruct the adductor musculature pterodactyloid skull detail, using osteological correlates extant phylogenetic bracketing...
The Chaoyangopteridae is a clade of azhdarchoid pterosaurs that stands out in China, particularly the Jehol Biota, as Cretaceous group medium-sized and high-crested pterosaurs. Herein, we describe new species, Meilifeilong youhao gen. et sp. nov., based on two specimens, one tentatively referred to this taxon. This species represents most complete well-preserved chaoyangopterid recorded date. Along with set characters (low premaxillary crest above nasoantorbital fenestra extending...
Pterosaurs, flying reptiles that lived during the Mesozoic era, were first vertebrates to develop powered flight. Despite being patchy, pterosaur fossil record extends worldwide, quite diverse at Araripe Basin, Brazil. The Romualdo Formation (Aptian-Albian), a Konservat Lagerstätten rich in calcareous concretions, has yielded several of these exceptionally well-preserved, three-dimensional fossils. MN 4727-V, focus present study, consists exclusively three-dimensionally preserved...
Many countries in the Americas have detected local transmission of multiple arboviruses that cause febrile illnesses. Therefore, laboratory testing has become an important tool for confirming etiology these diseases. The present study aimed to compare sensitivity and specificity three different Zika virus detection assays. One hundred serum samples from patients presenting with acute symptoms were tested using a previously reported TaqMan® RT-qPCR assay. We used SYBR® Green conventional PCR...
Pterosaur remains are found in numerous deposits of the world, but most isolated and fragmentary elements. This is case Japan where a small number specimens from those volant reptiles have been reported. Here, we redescribe first pterosaur (NSM PV15005) that were outcrops Upper Cretaceous Yezo Group (Santonian–lower Campanian) Mikasa area Hokkaido. Further preparation this material revealed several bones, including distal end left femur, non-ungual phalanx proximal caudal vertebra. Based on...
Armadillos (Xenarthra: Dasypodidae) are among the most conspicuous and peculiar groups of mammals, characterized by an armor osteoderms covered keratinized scutes. They widespread in South America, with one species (Dasypus novemcinctus Linnaeus) also reaching southern North America (Wetzel 1985, Aguiar & Fonseca 2008; Gardner 2008). Following latest revision subfamily Dasypodinae Mondolfi 1979), single genus Dasypus is partitioned into three subgenera: Dasypus, Cryptophractus...
