Paleoblog on Placental Evolution

The juicy bit that Dr Ryan emphasized in his own post:

The revised time at the root of placental mammals was much younger than the preceding reports, 84 million years ago instead of around 122 million years ago.

Ouchie. That puts some pain where it belongs. Go read.

Nice. I'll definitely have to check this out (especially since I remember that mammalian supertree coming out last year and going "Wha?!" when I saw some of the numbers). Thanks for passing this along, Will.
