The rich fossil record of the family Equidae (Mammalia: Perissodactyla) over past 55 MY has made it an icon for patterns and processes macroevolution. Despite this, many aspects equid phylogenetic relationships taxonomy remain unresolved. Recent genetic analyses extinct equids have revealed unexpected evolutionary a need major revisions at generic, subgeneric, species levels. To investigate this issue we examine 35 ancient specimens from four geographic regions (South America, Europe,...
Evolutionary theory has long proposed a connection between trait evolution and diversification rates. In this work, we used phylogenetic methods to evaluate the relationship of lineage-specific speciation rates mode body size tooth morphology in Neogene Quaternary radiation horses (7 living 131 extinct species). We show that pulses are recurrent feature equid but these not correlated with rapid bursts phenotypic evolution. Instead, cladogenesis seems repeatedly associated extrinsic factors...
Abstract This study aims at assessing resource and habitat use, niche occupation trophic interactions from a stable isotope perspective on fossil mammals the Argentine Pampas during Great American Biotic Interchange (GABI). We present data of more than 400 samples belonging to 10 mammalian orders spanning temporal range ~9.5 Ma ~12 ky. Rodents, notoungulates pilosians record an increase in consumption C 4 plants, whereas litopterns cingulates show δ 13 values that remain mostly within 3...
Se describe el cráneo más completo de gonfoterio procedente Pains (Estado Minas Gerais, Brasil) y se compara con otros restos esta familia procedentes otras localidades brasileñas. analizan algunos sus caracteres importantes gonfoterios provenientes distintas Iocalidades America del Sur. identifica como Stegomastodon waringi. Los Toca dos Ossos (Bahia) Bonito (Mato Grosso) también son identificados Nosotros consideramos que todos Ios Gomphotheriidae brasileños deberían incluirse en una única...
To reconstruct the paleodiet and habitat preference of gomphotheres, we measured carbon oxygen isotope composition 68 bone tooth samples for three species Gomphotheriidae from 24 different localities (Argentina, Bolivia, Ecuador, Chile, Brazil). Additionally, isotopic in phosphate 30 to control diagenetic alteration. We calculated correlation between pairs δ18Op-δ18Oc values enamel, dentine, bone, taken same individual order verify whether structural apatite carbonate was equilibrium with...
Climatic and environmental shifts have had profound impacts on faunal floral assemblages globally since the end of Miocene. We explore regional expression these fluctuations in southwestern Europe by constructing long-term records (from ∼11.1 to 0.8 Ma, late Miocene–middle Pleistocene) carbon oxygen isotope variations tooth enamel different large herbivorous mammals from Spain. Isotopic differences among taxa illuminate ecological niches. The δ13C values (relative VPDB, mean −10.3±1.1‰;...

Ancient DNA extracts consist of a mixture endogenous molecules and contaminant templates, often originating from environmental microbes. These two populations templates exhibit different chemical characteristics, with the former showing depurination cytosine deamination by-products, resulting post-mortem damage. Such modifications can interfere molecular tools used for building second-generation libraries, limit our ability to fully characterize true complexity ancient extracts. In this...
Proboscideans were keystone Cenozoic megaherbivores and present a highly relevant case study to frame the timing magnitude of recent megafauna extinctions against long-term macroevolutionary patterns. By surveying entire proboscidean fossil history using model-based approaches, we show that dramatic Miocene explosion functional diversity was triggered by their biogeographical expansion beyond Africa. Ecomorphological innovations drove niche differentiation; communities accommodated several...
Abstract Background Stable isotope ratios ( 13 C/ 12 C and 18 O/ 16 O) in fossil teeth bone provide key archives for understanding the ecology of extinct horses during Plio-Pleistocene South America; however, what happened areas sympatry between Equus (Amerhippus) Hippidion is less understood. Results Here, we use stable carbon oxygen isotopes preserved 67 tooth samples seven species from 25 different localities to document magnitude dietary shifts ancient floral change Plio-Pleistocene....
Hippidions were equids with very distinctive anatomical features. They lived in South America 2.5 million years ago (Ma) until their extinction approximately 10 000 ago. The evolutionary origin of the three known Hippidion morphospecies is still disputed. Based on palaeontological data, could have diverged from lineage leading to modern before Ma. In contrast, a much later divergence date, nesting within equids, was indicated by partial ancient mitochondrial DNA sequences. Here, we...
