Revisiting the oldest known lithic assemblages of Colombia: A review of data from El Abra and Tibito (Cundiboyacense Plateau, Eastern Cordillera, Colombia)

The aim of this paper is to present a review of the data referred to some of the earliest Colombian archaeological sites, i.e. Tibito 1, El Abra 2 and El Abra 3 (Cundiboyacense Plateau, Eastern Cordillera).The re-analysis of the lithic assemblages, according to a techno-typological approach referred to the lowest levels of these sites, traditionally considered the oldest and most significant sites of Colombia, has highlighted several discrepancies and critical elements in reference to the analysis of the lithic industry and the effective association between cultural elements and stratigraphy.Our review reveals that the evidence of human occupation of the oldest levels of these sites is reduced to a few artefacts, from which it is not possible to infer any kind of interpretation

New Insights on the Oldest Lithic Assemblages of the Tibitó and El Abra Sites (Sabana de Bogotá, Eastern Cordillera, Colombia)

In this paper we present a review of the oldest lithic assemblages of Tibitó 1, El Abra 2, and El Abra 3 (Sabana de Bogotá, Eastern Cordillera), among the oldest and most significant sites in Colombia. The contribution of use-wear analysis on a controlled sample of materials confirms and adds new data to our previous technological review Muttillo et al. (2017. “Revisiting the Oldest Known Lithic Assemblages of Colombia: A Review of Data from El Abra and Tibitó (Cundiboyacense Plateau, Eastern Cordillera, Colombia).” Journal of Archaeological Science: Reports 13: 455–465). The results highlight some critical points and discrepancies with previous studies and interpretation

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
