This week in the journal Nature, a team of researchers from Uppsala University in Sweden, the European Synchrotron Radiation Facility (ESRF) in France and the University of Cambridge in the United ...

DURHAM, N.C. -- New evidence gleaned from CT scans of fossils locked inside rocks may flip the order in which two kinds of four-limbed animals with backbones were known to have moved from fish to ...

The first 3D reconstruction of the skull of a 360 million-year-old near-ancestor of land vertebrates has been created by scientists from the Universities of Bristol and Cambridge, UK. The 3D skull, ...

NOVA: How did this new idea come about? Clack: The new idea stems from the material we collected in East Greenland in 1987. That proved to be a really rich haul of material, though it took several ...

Almost half a billion years ago, dry land was dominated by plants—at least until tetrapods (four-legged animals) crawled out of the water and onto the shore in one of life’s most vital evolutionary ...

Some 360 million years ago, a school of juvenile lizard-like creatures ? with no parental chaperones around ? perished in a watery grave in what is now Greenland. That's the story researchers have ...

As one of the earliest tetrapods, Acanthostega gunnari can tell us a lot about the anatomy and ecology of the vertebrates which moved onto land. Unfortunately, none of the fossil specimens includes an ...

A study of the jaws of one of the earliest known limbed vertebrates shows the species still fed underwater, not on land. Scientists from the University of Lincoln, University of Zurich, University of ...

Researchers have shown that fossils of the 360 million-year-old tetrapod Acanthostega, one of the iconic transitional forms between fishes and land animals, are not adults but all juveniles. This ...

The first 3-D reconstruction of the skull of a 360-million-year-old near-ancestor of land vertebrates has been created. The 3-D skull, which differs from earlier 2-D reconstructions, suggests such ...
