Figure 4: MGUH VP 6139, skull, shoulder girdle, thoracic and presacral region of Ichthyostega. If we are correct and the axial morphology did not permit lateral trunk flexion in Ichthyostega, two ...

Figure 1: Three-dimensional reconstruction of Ichthyostega from μCT scan data. Figure 2: Maximum ranges of mobility in the limb joints of Ichthyostega and five modern tetrapod analogues. With respect ...

Palaeontology has gone high-tech: no more wax and plaster-cast models. Instead, 3D data from computed tomography (CT) scans is overturning long-held views of how the earliest land animals moved. One ...

One of the most important milestones in the evolution of life began some 400 million years ago, when the first animals made their way from water onto land. At that time, known as the Devonian period, ...

First steps The world's first 3D reconstruction of a four-legged animal backbone reveals that the first animals on land moved like seals. One of the studied animals was a fierce-looking, toothy beast ...

The transition from swimming to walking involved some awkward first steps, according to a new study that recreated how one of the first animals, which left the sea for land, moved. The study found ...

A reconstruction of the skeleton of the first four-legged land animal suggests that it didn't move too nimbly on land - it either shuffled along or crept like an inchworm. 360 million years ago, ...

I love outdated museum displays. They marvelously represent the “history” part of natural history exhibits – dusty dioramas of old ideas that are a baseline for how much our understanding has changed.

One of Earth's earliest four-footed land animals couldn't walk, a new 3-D model suggests. Instead, the dog-size Ichthyostega likely flopped on land, using only two of its four stubby legs for ...

One of the first creatures to walk on land didn’t scamper gracefully out of the waves. Instead, the creature, known as Ichthyostega, would have hauled itself up on its front limbs like it was on ...
