Chihuahua-sized fossil "beardogs" shed new light on evolution of dogs and their relatives

Fossil discoveries don’t always happen out in the field, with scientists armed with pick-axes realizing they’ve found something special. Sometimes, fossils lie in wait in museum collections until the right researcher comes along and realizes there’s something unusual about them. That’s what happened this time, and the fossils in question are prehistoric dog relatives called “beardogs.”

SUE Lends a Hand: Field Museum Scientists Remove T. rex’s Arm for Argonne Study

Two Field Museum scientists are leaving their labs and going face-to-face with SUE, the biggest Tyrannosaurus rex ever discovered, armed only with a wrench. And they’re going to take her arm off. SUE’s not just the world’s biggest T. rex—she’s also the best-preserved and most complete one. And that means that she contains a treasure trove of information for paleontologists to learn from.

And to figure it out, the scientists analyzed the DNA of some of the cutest animals on earth—mouse lemurs.
