Archaeologists uncover evidence confirming Les Coves Llongues site was inhabited during Early Neolithic, highlighting the Bergantes River as a key route for early farming communities. The site's strategic location along a natural corridor connects the Iberian Mediterranean to the Ebro Valley.
Scientists used lithium isotope data to show that continental clay export promoted organic carbon burial and thus atmospheric oxygenation during the Cambrian period. This finding challenges traditional views on marine oxygen levels during this time, suggesting a complex interplay between oceanic and atmospheric processes.
A study led by Gabriel Filippelli suggests that the evolution of tree roots during the Devonian Period caused massive algae growth, depleting ocean oxygen and triggering mass extinctions. The researchers found that tree roots released excess nutrients into the oceans during times of decay, leading to catastrophic events.
Marine biodiversity experienced two bursts of accumulation during the Cambrian Explosion and Great Ordovician Biodiversification Event. The latter coincided with falling equatorial sea-surface temperatures, suggesting a narrow temperature window was required for marine life.
Scientists recognize Anthropocene epoch, a new geological time period caused by massive human impact, which may lead to the Earth's sixth-largest mass extinction event. The term has gained widespread support within the geological community and could be formalized as a new unit on the Geological Time Scale.
Researchers suggest that humans have altered the planet so much that we are entering a new geological time interval, potentially sparking a mass extinction event. The proposed Anthropocene Epoch marks a significant shift in human influence on the environment.
Researchers from Yale University and the Imperial College have digitally reconstructed a fossilized brachiopod complete with its pedicle and lophophore, revealing new insights into extinct forms. The discovery sheds light on the evolution of brachiopods and challenges previous assumptions about their similarities to modern examples.
Researchers found attacks on brachiopods were rare but widespread during the Paleozoic Era, with predators likely mistaking them for other prey. The findings hint at how the food chain changed over time as predators diversified and prey groups became better armored.
A study of fossilized brachiopod shells reveals that predators were a constant threat throughout the Paleozoic Era, with subtle increases in predation traces suggesting escalating predation pressures. The findings suggest that marine ecosystems have become increasingly hostile to survival, consistent with macroevolutionary models.
