FOSSILS from two early whales, a male and a rare pregnant female, have shed light on how whales made the leap from walking on land to ruling the sea.
The fetal remains, found with the 47.5 million-year-old pregnant female, were positioned head down, suggesting these creatures gave birth on land, while spending much of the rest of their time in the water...
...Both fossils had four flipper-like legs that could have supported their weight on land, but only for short distances, suggesting these whales likely came on shore to mate, rest and give birth, Dr Gingerich said.
