According to that, I believe that picture 1 shows  (from top to bottom): 
1 Upper Left C in lingual view, because in this side the crown surface is more or less flat, and clearly shows two ridges running from the gumline almost to the tip
2 Lower Left C in labial view, in this side of the crown the surface is curved, without ridges, but sometimes with grooves 
3 Lower Right C in labial view, like the previous one,
and 4 Upper Right C in lingual view, like in 1. 

Then, I thought picture 2 showed the same four canines but flipped to show the other side...  but no.  Now it seems to me they are:

1 Upper Left C in labial view; curved crown surface, no ridges, one slight groove, gumline (enamel-dentin line) more or less straight and almost perpendicular to the tooth axis
2 Lower Right C in labial view; curved surface, no ridges, small groove, gumline skewed from tooth axis
3 Lower Left C in labial view, like in 2
4 Upper Rigth C in labial view, like in 1

No Lower Canine was shown in lingual=inner view 
 
My questions are: 
Do you think it is the same set of fangs in the two pictures?  In picture 1 they seem much wider (fatter?) than in picture 2, but this may be due just to the different framing angle of the picture. Or jaguar fangs may show such an individual difference?  May you or Betty confirm that? 
How long are the cigarettes (in China) ?, may be 83 mm?
Do you know if it is possible to estimate the age class of a jaguar according to the condition of the root (hollow/solid, wide/narrow)?, by looking with X rays?, or by finding some ratio between weight and length? 

Thanks for your patience!   Jaguar

I am learning about jaguar fangs, and these two pictures were great to practice (and to show me that I was wrong?).  I assumed the two pictures showed a full set of canines (\'C') from the same individual cat, upper ones at the sides of each group, and lower ones at the center next to the cigarette. Also, I think (thought?) it is possible to say if the picture shows the lingual = inner face of the tooth, or the labial = outer side of the tooth. Reply
