New reconstruction of the skeleton of the 375-million-year-old fossil fish, Tiktaalik roseae. In a new study, researchers used Micro-CT to reveal vertebrae and ribs of the fish that were previously hidden beneath rock. The new reconstruction shows that the fish’s ribs likely attached to its pelvis, an innovation thought to be crucial to supporting the body and for the eventual evolution of walking.

The eruption and volcanic material sedimentation processes of giant caldera eruptions are not well understood, making it also difficult to estimate their size. Kobe University researchers used seismic reflection surveys to visualize the sedimentary structure and analyzed collected sediment samples, enabling them to obtain important information on the distribution, volume, and transport mechanisms of the ejecta. © SHIMIZU Satoshi (CC BY)
