Researchers have discovered that changes in African topography led to enhanced South Asian summer monsoon precipitation during the Early to Middle Miocene. This phenomenon was driven by altered atmospheric circulation patterns and moisture transport, resulting in increased convective activity and strengthening of the monsoon. The findi...
A new fossil discovery in Spain has effectively doubled the evolutionary history of the weasel family, dating back to around 6.5 million years ago. The fossil, named Galanthis baskini, was found in Teruel, Spain, and is estimated to be around 5 ounces in size.
A University of Cambridge-led team analyzed giant anaconda fossils to determine their maximum size occurred 12.4 million years ago. The study found that ancient anacondas were four to five metres long, matching the size of modern anacondas, suggesting they have remained giants due to a suitable environment.
Researchers analyzed chloroplast genomes of cacao trees from northern Peru to determine the species' age and diversity. The study found that the current known diversity diversified during the Pliocene or Miocene epochs, approximately 7.5 million years ago.
A 15-year study of an ancient ecosystem in Bolivia provides a comprehensive view of the Earth's past, revealing warmer temperatures and lower elevation. The team found fossils of diverse animals and plants, reconstructing the site as a dry forest or wooded savanna with palms and bamboos.
A team of experts discovered a dugongine sea cow attacked by an ancient crocodile and tiger shark, shedding light on prehistoric food chains. The fossils showed signs of both active predation and scavenging, providing new insights into the region's food chain networks during the Miocene epoch.
A new species of great ape, Buronius manfredschmidi, has been identified from the Hammerschmiede fossil site in Bavaria, Germany. The species is estimated to have weighed around 10kg and had a distinct lifestyle from the larger-bodied Danuvius, allowing for cohabitation without resource competition.
A team of paleontologists has discovered the oldest record of sea turtle DNA in a fossil shell from Panama's Caribbean coast. The findings, published in Journal of Vertebrate Paleontology, date back approximately 6 million years to the upper Miocene Epoch.
A research team from Hokkaido University has found an exceptionally preserved fossil forest of Wataria parvipora, which was predominantly accompanied by Byttneriophyllum leaves. The discovery helps reconstruct a whole Eurasian plant from the late Miocene epoch and sheds light on the taxonomic identity of plants.
Researchers used pollen records from four montane conifers to estimate past elevation of northern Tibet Plateau, revealing rapid uplift during the Middle to Late Miocene epochs. The study supports prevailing theoretical models of Tibet Plateau formation and highlights its impact on atmospheric water vapor transport and rainfall patterns.
A new panda species, Agriarctos nikolovi, has been discovered in Bulgaria, which may have been Europe's last known giant panda. The fossilized teeth, found in the late 1970s, suggest that this ancient panda consumed a largely vegetarian diet, unlike modern pandas.
A team of Australian and international scientists has discovered a valuable new fossil site in New South Wales, containing exceptional examples of fossils from the Miocene epoch. The site, named McGraths Flat, provides insights into the history of the Australian continent and its ecosystems.
Researchers describe a new modern-looking tardigrade fossil, Paradoryphoribius chronocaribbeus, found in Miocene Dominican amber. The study reveals unique foregut organization and contributes to the scant tardigrade fossil record, providing insight into the ancient superfamily Isohypsibioidea.
Researchers discovered a shared skeletal structure between African and American crocodiles, suggesting a close evolutionary relationship. This finding proposes that crocodiles migrated from Africa to America, reaching the Americas via Australasia around 7 million years ago.
A new extinct shark species, Megalolamna paradoxodon, was identified from fossilized teeth in the eastern and western United States, Peru, and Japan. The shark lived during the early Miocene epoch and is a close cousin of the megatoothed lineage, with characteristics similar to the modern-day salmon shark.
