My blogfather Jeff links to this fascinating story about giant rodents the size of a buffalo:

A rodent the size of a buffalo? Researchers say they have found fossils for a 1,545-pound giant that thrived millions of years ago in a swampy South American forest.
“Imagine a weird guinea pig, but huge, with a long tail for balancing on its hind legs and continuously growing teeth,” said Marcelo R. Sanchez-Villagra of the University of Tubingen in Germany, the first author of a study appearing this week in Science.

Well, over at TTLB I keep vacillating between being an Adorable Rodent and a Marauding Marsupial. The way I see it, either way my teeth are continuously growing.
Jeff asks, “Imagine the size of the cats that went after those things. Could that be how Saber-Toothed Tigers came about? Imagine the traps you’d have to set…”
Well, I’ll remind everyone that when I am in my Marauding Marsupial phase I am the next thing to a Saber-Toothed Tiger! My favorite marsupial is Thylacosmilus.
All missing links cheerfully devoured!
