Only placental beings require a navel, which is the former connection to the umbilical cord. Reptiles are definitely not placental.

[gundog]

I know that turtles have an umbilicus that closes up as they develop.

[dfwgator]

Innies or Outies?

[BipolarBob]

Thank goodness they cleared this up. I can die happy now knowing this discovery. It ranks up there with those deep existential problems I've pondered since . . well forever along with just how far would I go for a Klondike bar.

I’ll bet they were irresistible in a bikini.

Calling dinosaurs reptiles?

[Theophilous Meatyard III]

[Rebelbase]

This is the kind of theory that deserves millions in Federal grants.

[Pilgrim's Progress]

How many millions of our tax dollars was spent in discovering this fictional proposition?

[Secret Agent Man]

It’s not actual science when the article title says “may”...

That’s called “speculating”, or “fantasizing”...

[LastDayz]

Wonder if they stood around and stared at them like our useless RINO’s. Maybe even picked out the lint, rolled them into little balls and pitched them at each other.
