*Gobiconodon* (cat-sized) is EK. *Kollikodon* (the _1-m-long_ platypus with
apparently a beak and 4 molars per dentary, probably harmless to eggs) is
also EK. *Stagodon* is supposed to have been much like the Tasmanian Devil
rather than an important nest predator...
What should have caused such a relaxation on mammal size constraints, and
where do you find such a relaxation?
Must've missed the post awhile back about the largest known Mesozoic mammal
from the _Early_ Cretaceous:
