Several locations are known along the coast of the Ezequiel Ramos Mexía Dam, Neuquén province in Northwestern Argentinian Patagonia, comprising one of the richest dinosaur-tracking areas in South America. In this contr...

This contribution describes new vertebrate remains found in Triassic strata informally known as “Estratos ElBordo”, in the Atacama Desert, northern Chile. These include the first temnospondyl record in the El Bordo B...

Today, only three odontocete (toothed whales) genera are restricted to freshwater habitats: the Amazon River dolphin (Inia geoffrensis), the possibly extinct Yangtze River dolphin (Lipotes vexillifer) (Turvey et al., 200...

Anthropologists have searched fruitlessly for the Peking Man fossils for almost eighty years. Writers have made many unwarranted claims about the loss of the fossils, starting with the assumption that they were transferr...

A palynomorph with an unequivocal relationship to the eight-grain polyads of the mimosoid genus Calliandra Benth., is described from the Miocene sediments of San Juan Province, Argentina. Comparison of the fossil palynom...

The aculeate family Bethylidae is represented in Baltic amber by about 40 species. We here describe and figure a new species in the subfamily Epyrinae from this late Eocene deposit: †Gracilepyris carsteni sp. nov., ba...

The conifer family Araucariaceae is characterized by a relatively small extant diversity, especially comparedwith its rich, diverse and worldwide distribution in the fossil record. Most of the Mesozoic record ofAraucaria...

Selective electrochemical CO₂ reduction to multi-carbon products remains a central bottleneck for carbon-neutral chemical manufacturing, with most catalysts achieving C₂⁺ Faradaic efficiencies below 75%. This inves...

"The renewed concern for the care of the environment has led to lower emissions of greenhouse gases without sacrificing modern comforts. Widespread proposal focuses on energy produced from renewable sources and its subse...

Efforts to conserve fuel oil (BBM) promoted by the Indonesian government and many other countries are motivated by the fact that fossil fuel availability has decreased and environmental pollution continues to worsen. Str...

Abstract The Alum Shale Formation of Baltica preserves one of the most continuous and fossil-rich records for the Cambrian Period. Thus, the Alum Shale is a key sedimentary archive for refining global chronostratigraphy,...

Third-generation biomass constitutes a renewable energy source that could substitute fossil fuels. This study evaluated the biomethane potential (BMP) of Ulva sp., Codium sp. and Undaria pinnatifida through anaerobic dig...

Over more than six decades of dedicated research, Chang Meemann’s career has spanned a critical era marked by a paradigm shift in vertebrate evolution studies. Beginning in the 1950s, inspired by the pioneering ichthyo...

Niche construction theory has increasingly received attention in paleoanthropology as a new focus for considering the evolutionary consequences of hominin tool-use and cultural adaptation starting in the Pleistocene. Mod...

Abstract The Eocene–Oligocene transition was the crucial turning point when Earth’s climate shifted to its current icehouse state. Understanding how the marine biosphere responded during this transition is not well-c...

Octodontoidea is the most species-rich cladeamong hystricomorph rodents. Based on a combined parsimonyanalysis of morphological and molecular data of extinctand extant species, we analyze the history of SouthAmerican oct...

Melanosuchus niger (Crocodylia, Alligatoroidea) is one of the six living caimanine species widely distributed throughout the Amazon River basin today. Although there is only one extant species of Melanosuchus, fossil mat...

The family Cardiliidae has been scarcely studied. It was historically placed in the superfamily Mactroidea. Members of this family are characterized by a cordiform shell with a typical mactrid hinge, posterior adductor m...

Resumo É apresentado um histórico das atividades do Departamento de Botânica desde a sua criação em 1954, quando foi denominado de Serviço de Estudos Florestais, depois (1956) Centro de Pesquisas Florestais, que ap...

Abstract The bony palate of palaeognaths was long thought to retain the plesiomorphic condition for crown birds, but recent fossil evidence suggests that aspects of palaeognath palate morphology are derived from a neogna...

The Chubut River is a Patagonian river that flows from the Andes to the Atlantic Ocean, and is interrupted by a dam built at the middle valley. To investigate the sedimentary history of the lower river basin, a sediment ...

The use of renewable energy is one of the priorities of common EU policies to achieve carbon neutrality and mitigate the effects of climate change. On the other hand, the protection of biodiversity, which also contribute...

The fragmentary early Homo fossil record represents a temporally expansive and complex lineage that is morphologically and geographically diverse. This large amount of variation, which also captures the transition period...

This study aims to test the effectiveness of sawdust as an alternative fuel to replace coal in a 50 MW power plant in an effort to reduce dependence on fossil fuels and have a negative impact on the environment. The use ...
