Am I just tired, or is “new prehistoric” kind of funny?

Silly palaeontologists. Discovering Felinae fossils is damn easy: you put a fossilised cardboard box on the floor, and the fossils will gather inside it!

I’m joking. Serious now, Wikipedia has some interesting bits of info, including the origin of the name (mageri- is from Magerit, a historical name for Madrid; and peignei is a homage to Stéphane Peigné, a palaeontologist friend of the authors) and a nice cladogram.
