Ancient Wings

Scientists have believed that Archaeopteryx (“Ancient Wing”) had a “perching toe” (just like birds), which helped them to grasp branches of trees. However, a new extremely well preserved fossil of Archaeopteryx from Thermopolis, has been found to have no perching toe at all. This limestone encased fossil also has one of the best-preserved skulls of all specimens ever found. However, it is the feet that are the centre of attraction as all previous fossils had rather shriveled up feet, but not this Thermopolis specimen. The feet, have a thumb-like extension from the side of the foot rather than from the back. So the ancient winged fellers might not have been exactly swooping from the skies on their meals, but rather furtively scouring around and over bushes in pursuit of their natural motives.
