Cliff collapse reveals 313-million-year-old fossil footprints in Grand Canyon National Park

The structure of the trabecular, or spongy bone that forms in the interior of bones, is unique within dinosaurs, according to a recent study by SMU paleontologists and others.

Fossil Pollen Record Suggests Vulnerability to Mass Extinction Ahead

Phenotypic difference between each specimen for each landmark in the 11-module dataset and the mean skull shape.For each specimen, the mean landmark configuration is plotted with points coloured relative to the Procrustes distance between the position of that point in the mean shape and in that specimen. Warmer colours denote landmarks having higher displacement from the mean, and cooler colours are more similar to the mean shape. Data and code archived at www.github.com/rnfelice/Dinosaur_Skulls .

Bird skull evolution slowed after the extinction of the dinosaurs

A team of researchers led by professor Brian Fields hypothesizes that a supernova about 65 light-years away may have contributed to the ozone depletion and subsequent mass extinction of the late Devonian Period, 359 million years ago. Pictured is a simulation of a nearby supernova colliding with and compressing the solar wind. Earth’s orbit, the blue dashed circle, and the Sun, red dot, are shown for scale.
