Mystery mammal jaw

A woman brought me these pictures of a jaw she found by her house yesterday.  The location is southern Great Lakes.  The pics are blurry, but she’d love to know what it is.  A little help?

    Looks like a piece of a smallish ruminant’s jaw – deer, sheep, or goat.

  2. What SB said. Probably deer (I am assuming that domesticated animals like sheep would not be allowed to go around dying and rotting away).

  3. Deer are endemic, pretty much the only thing around here that chews and chews and chews the vegetation, AFAIK.

  4. Looks like part of the upper jaw of a white-tailed deer to me.

    Left maxilla of a deer. P3, P4 and all three molars. I can’t see the color of its tail from here.

  6. Wow, I’ve got some serious knowledge/brain power helping out. Thanks, folks. I forwarded it to the interested party.

    We used to age jawbones of moose and deer for management purposes back in the 90s, so based on the blurry photos and my blurry memory, it looks about a year class 2 (about 2 years, 2 1/2 if it died in hunting season) or perhaps younger (can’t tell if that third molar is fully erupted or not). Regardless, the teeth don’t look very worn at all (crests sharp, dentine confined) so it is a young animal. Google “aging”, “deer” and “jaws” will get anyone interested more info. (just checked–yep, good stuff there).

    p.s. aging usually is done on lower jaws, not upper, but in a pinch, upper can approximate too.

    The Loch Ness Monster got sick on a trip to the Great Lakes, found that no one would take her NHS insurance in the US and ended up dying in a corner some place because she couldn’t afford to pay for the “non-emergency” care needed to save her life? (In other words, I have no idea, with gratuitous slam at the US (lack of) health care system.)

    Yes, there is a reason that I’m being cranky about the problems of coverage for non-US residents, but it’s not HIPAA compliant.

    Anyone with two ears to hear with can see it is from a Sasquatch.
