Oxtail from MAC Rhino Fonts
Ivan Bettger, writing for Typekit:
Oxtail is a bracketed slab serif typeface; on first glance at the caps, you might be reminded of Clarendon, for which Oxtail is an excellent alternative. But what makes Oxtail special is the tapered finials found in the lowercase set (as well as the cap R and Q). Angled slab serifs sit atop vertical and diagonal strokes, in strong contrast to the pointy, script-like tails.
