The fossil, which measures less than a quarter-inch long, is believed to be from the middle or late Jurassic Period, perhaps 170 million years old. Researchers said it suggests that mammals developed independently in the Southern Hemisphere.

The fossil, named Asfaltomylos patagonicus, was discovered in a mudstone formation in the province of Chubut, 950 miles south of Buenos Aires. The now-arid region also has yielded some remarkable dinosaur fossils from the same era in a vast ancient boneyard covering hundreds of square miles.

Most early mammal species are identified by peculiar cusps, bumps or points on their teeth.

This will come as a shock to some of the participants on these threads -- well, one in particular -- who keep proclaiming that mammary glands are the only TRUE mark of a mammal, early or modern.

New motto: bicuspids, not boobies!

Oops. Sorry. Though I can't wait to spring it on certain mammary-gland-obsessed posters on these threads.

Um, not those of us with a normal, healthy obsession, if you know what I mean.

Researchers from Germany and Argentina reported in the current issue of the journal Nature that Asfaltomylos belongs to a branch of southern egg-laying mammals that are extinct today except for the platypus and echidna of Australia. It is distantly related to Jurassic mammals found in Madagascar and Tanzania.

I can use that in the discussons I have all the time with platypus lawyers who say the monotremes came from nowhere and had no relatives.

Researchers said it suggests that mammals developed independently in the Southern Hemisphere.

But I really didn't need to read that. I hope it's just the science writer blurring up a mess.
