Which of Thewissen and Hussain's summary would you go by? 1993 or 2001?
You New Scientist article citing Thewissen and Hussain's review of Pakicetus was written in 1993.
Why don't you contact Thewissen and Hussain and ask them why they changed their mind 8 years later and wrote, "Pakecetids were terrestrial mammals, no more amphilbious than a tapir."
