Whalevolution Month #06 – Remingtonocetus Known from near-shore and lagoon environments in Pakistan and India, Remingtonocetus lived around 45-43 million years ago and grew to about 3.4m long (~11ft). While in the water it probably swam using a combination of undulatory movements and paddling with its hind limbs, similar to modern otters.
