The first land-walking vertebrates may have emerged from salty estuaries
Pincho says...
It's so obvious that they were in fact worms which were growing legs at the time.

The first land-walking vertebrates may have emerged from salty estuaries
Early tetrapods, such as Ichthyostega and Acanthostega, lived an amphibious existence between land and sea: They had feet, but also gills and tails made for swimming. A new study by paleontologist Jean Goedert of Université Lyon in France and colleagues suggests that the animals also could have tolerated rapid changes in salinity, such as is found in an estuary.
