The Prehistoric Whale That Walked On Land

The Prehistoric Whale That Walked On Land The largest animal that has ever lived — the blue whale — began as a wolf-sized hunter that walked on four legs, fifty million years ago. This is the story of Pakicetus: a four-legged, hoofed land animal from the Eocene shore of the Tethys Sea that already carried a whale's ear. The skull Philip Gingerich misread as a land predator in 1981 — until a single ankle bone, recovered in 2001, proved that whales are hoofed animals whose closest living cousin is the hippopotamus. The blue whale still carries its grandfather's ankle in its blueprint, and its hips in its flesh. It was the sea's first draft. ━━━━━━━━━━━━━━━━━━━ 📚 SOURCES 1.
