Sorry
to jump in so late.
Richard;
the lower M3 of bear is far too large/long. Julia indicated
it is about 8 mm, the one from bear is about 18-20 mm. I
have 2.5 months and 9 months old bear cubs, I think I can
exclude bear.
Then,
just a thought: Lower M2 of badger. Does not fit completely
with the specimens at hand, but if Julia could check the
original tooth, might be worth a try,
cheers,
Vern

I imagine the unerupted crowns of deciduous bear teeth are
only a little less scarce than the proverbial hens' teeth.
However the illustrations here look promising, particularly
the lowest left illustration.

Julia - you would do us a favour if you Dropboxed some more
pictures of the tooth - in particular one looking down onto
the occlusal surface.

Re:
[ZOOARCH] Friday tooth quiz
Richard, you are a careful worker. Happily we have textbooks
to tell us
what unerupted baby teeth look like. However, now that
you've made it
possible for me to see the images -- geez, I agree with your
first
observation more strongly. Those cusps are pretty darned
high and pointy!
I now think it's not a pig; cusps too high and the tooth is
too fat and
wide for an inferior tooth of a pig. But somebody on this
list suggested
"bear"....does anybody have a bear cub to compare to? I have
adult bear
but no cubs. Just to make double sure if nothing else. --
