Camel teeth? In North America 15,000 years ago?
Were there any native camels in North America at the time?

[snip] ...during the Eocene period, 44 million years ago... The Megatylopus was said to be between 12 and 14 feet tall and functioned much like a giraffe when it lived approximately 7 million years ago... Around six to seven million years ago, early camels known as Paracamelus started leaving North America by crossing into Eurasia across the Bering Strait. Once the early camel ancestors arrived in Eurasia, they began branching off into the distinctive camel species we recognize today: the Bactrian camel and the one-humped dromedary camel. [/snip]
Yep there were and lot of other animals that no longer exist.

The only evidence that I found is that they invented Camel cigarettes...
Yes. There would have been mastodon in this area, as well.
