Zoology Lesson For Today, 2.0

Lower Jaw, White-tailed deer, Fawn, Pittsburgh, 2015

In my previous post about aging a white-tailed deer, Odocoileus virginianus, based on the wear on its teeth, I used as an example the skull and upper dentia of an adult deer.  Recently, while on a hike, our beagle found the lower jaw of a fawn.  Four teeth are fully erupted, with a fifth just breaking free of the bone.  Anytime there are fewer than six teeth in place on the jawbone, it is a fawn.  This particular fawn would've been very young.
