Terrestrial Triassic assemblages are an important component of the heritage of Argentina, particularly because of their diverse record of fossil vertebrates. Triassic basins from western Argentina have a good representat...

IGM 9026 is a singular fossil collected at the beginning of the 20th century in an improperly documented site within the Tlaxiaco Basin, near to Tlaxiaco town, Oaxaca, Mexico. The age of the site was suggested as being e...

The aim of this paper is to expand the current knowledge on the distribution, ecology and morphology of Pseudostaurosira cataractarum (Hustedt) C.E. Wetzel, E. Morales et Ector. We analysed several freshwater diatom asse...

Se presentan datos sobre una metodología de patrimonio geológico que pretende valorizar a los depósitos costeros (?beachrocks?, paleoacantilados y cordones litorales) del golfo San Matías del Pleistoceno Tardío. El ...

The recent discovery of pollen grains assigned to the earliest branch of Asteraceae from Cretaceous sediments in Antarctica prompted us to examine the pollen from five lesser known members of Asterales (Alseuosmiaceae, A...

Abstract The reliance on fossil-derived compounds in most conventional retanning agents faces a challenge to the sustainable development of the leather industry. Consequently, the development of environmentally friendly ...

Natural gas is a primary target for methane (CH _4 ) emissions reductions because this sector is among the largest sources of CH _4 in the United States; natural gas is a fossil fuel, so reducing gas use can also reduce ...

The record of the genus Tapirus in South America is associated with the faunistic events of the Great American Biotic Interchange (GABI). The taxon is considered an immigrant of Holarctic origin. Although remains are sca...

Abstract While the interbreeding of Homo neanderthalensis (hereafter Neanderthal) and Anatomically modern human (AMH) has been proven, owing to the shortage of fossils and absence of appropriate DNA, the timing and geogr...

This contribution presents new fossil insect taxa of the order Hemiptera (Cicadomorpha, Dysmorphoptilidae, Gallegomorphoptilinae subfam. n.) from the Ischichuca Formation (late Middle Triassic to early Late Triassic) fro...

Among the Middle Pleistocene African fossils that are central to discussions about the evolution of Homo sapiens is the partial cranium from Florisbad, South Africa. The fossil, dated to MIS 8 (300–243 ka BP), combines...

Humans utilise about 40% of the earth’s net primary production (NPP) but the products of this NPP are often managed by different sectors, with timber and forest products managed by the forestry sector and food and fibr...

The depletion of non-renewable fossil energy reserves is the main reason for this research to develop renewable energy as a substitute for diesel fuel. One of the alternatives studied is the production of biodiesel from ...

Neogene deposits of northwestern Argentina host an outstanding ichnological record of the Cenozoic vertebrate faunas developed within a context of continental isolation in South America. The Vinchina (Middle to Late Mioc...

ABSTRACT Bactris trunks are made entirely by long sustained primary growth so that mechanical properties develop progressively as the trunk matures. Anatomical features vary throughout the stem so that one small sample i...

Renewable energy is energy that comes from natural resources that are continuously available. Renewable energy will replace fossil fuels that will slowly run out, fossil fuels such as oil, gas and coal. Dependence on fos...

Dysnoetoporidae is a family of cheilostome bryozoans including only the genus Dysnoetopora Canu and Bassler, 1926, with three recognized species from the Late Cretaceous of the United States, Crimea, and Germany. The aim...

New species of Cryptaulax and Procerithium (Procerithiidae, Caenogastropoda) are reported from the Lower Jurassic (Pliensbachian-Toarcian) marine deposits of west-central Chubut province, Argentinean Patagonia. Three new...

The Peking Man skeletal materials, excavated in China in the 1920s and 1930s, disappeared in December 1941. The assumption that the fossils were acquired by the U.S. military has emerged as the core idea of what we call ...

This article describes the first fossils recorded in the Hernandarias Formation (Pleistocene) in Entre Ríos province (eastern Argentina). They are represented by three teeth assigned to the caviomorph rodents (Rodentia,...

The extensive reliance on fossil resources for fuels and platform chemicals has raised critical concerns over resource depletion and increasing greenhouse gas emissions. To address these challenges, microalgae offer a pr...

Los estudios neotafonómicos de vertebrados proveen información sobre los mecanismos y procesos que pueden modificar las características originales de los elementos esqueléticos de vertebrados actuales, y pueden usars...

Xujiayao, located in northern China, is an important paleoanthropological site because it dates to the late Middle Pleistocene (~200 ka - ~160 ka) and has a combination of hominin fossils, archaeology, and other vertebra...
