RE: Subterranean strategies

Hello!

As the discussion deals with K/T survival strategies: Once I have read
(don't know the source any more) that no animal heavier than 10-20 kgs
survived the K/T boundary.
I there really any evidence for this? What about crocodiles, sharks,
big turtles etc.? Did only survive very small species of these groups?
Or did bigger ones survive only as eggs (obviously lighter than 10 kgs)?

Best regards, Juergen Peters
