First walker
On the riverbed of an ancient river, an arm bone of more than 350 million years is discovered in Pennsylvania, USA.
Because of its bone appearance it is believed to belong to a four-limb aquatic being.
Paleontologists have spent time discussing whether the first moving being was aquatic or terrestrial. This discovery, along with other fossil remains, shows that in the water lived the first animals with feet instead of wings, the tetrapods.
