14. Two ways we know that Maiacetus was a whale re:
1) Their skeletons have all been found among fossils of sea-creatures which suggests they lived in the sea.
2) Their hip bones were strong enough to walk on land, but their short legs combined with long flat fingers and toes suggest they would have had difficulty walking.
15. The name Maiacetus means Mother Whale. Maiacetus is significant because of how well the skeletons were preserved.
