Mustelid

The wolverine is the biggest mustelid in existence.

1998, Vivian Banci, Chapter 5: Wolverine, Thomas E. Kucera, American Marten, Fisher, Lynx, and Wolverine: Survey Methods for Their Detection, Diane Publishing, page 99, Relative to smaller mustelids, the wolverine has a robust appearance, rather like a small bear.

Mustelid diversity is well reflected in the Neogene fossil record, in spite of the fact that mustelids are among the rarest of fossil carnivores.

The mustelid head has a low, flat skull and short face with small ears and eyes.
