Water flow simulations using 3D models of fossils yield new clues to the evolution of organisms known as medusozoans.
The Ediacaran features an instable magnetic field complicating paleogeographic reconstructions; a new paleointensity study on late Ediacaran rocks indicates a weak but stable dipolar field.
A new study describes eukaryotic organisms found organized in a cortex-medulla pattern in southern China’s Kuanchuanpu Formation.
A new study of seafloor sediments finds that the temperature record in the early Paleozoic corresponds to significant shifts in the diversity of life on Earth.
The 500-million-year-old species is a distant relative of today’s crabs, spiders, and insects.
In a new study, researchers make the case that large-scale glaciation during parts of the Neoproterozoic era led to extensive erosion of Earth’s crust.
The fossils include jellyfish, box jellies, branched algae, and sponges, which are underrepresented in or missing from other deposits.
Discovering new resting places of these rare and information-rich fossils will be critical to understanding the largest expansion of life in Earth’s history, according to researchers.
The search for fossil imprints and casts of squishy organisms takes time, perseverance, and sometimes a sprinkle of luck.
A researcher proposes a tectonic mechanism that could have helped drive one of the biggest evolutionary events in history: the Cambrian Explosion.
