There may be many objects that are shaped like sharks teeth (put the apostrophe wherever you would like, I've tired of them from writing about shark teeth), but the shape isn't the key.

 

(Answer:  Look 70% up and 30% right) Along the beach in South Carolina, they will generally have a deep shiny black color.  When wet, they shine as if freshly painted. 

 

 

 

 

 

 

A dog can provide great motivation for taking more walks.  This one deserves much of the credit for all of the teeth appearning on this website.  Look to the southwest of the paw to find this shark tooth.  Again, the color is the key.

 

 

 

 

 

Notice the long canine-like tooth in the picture.  Where the beach is flat, you may find these teeth parallel to the beach.  However, where the beach is more steeply sloping, the teeth will roll back with the outgoing wave, so when you do find them, they tend to be perpendicular to the water, because this is how they get caught by the sand.  Otherwise, they simply roll back out to sea.  (Shark's tooth is approximately west-southwest from the dog's foot.)

 

 

 

This one is fairly simple.  Right in the middle, just beyond the salt wave line.

 

 

 

Tooth just sitting there all by itself.

 

 

Small canine-shaped tooth laying perpendicular to the waves.  This is on a very slight slope.  On a steeper slope, this tooth would more likely have rolled back to the ocean.

 

 

This one was easy enough, but that is sort of the point.  The sharks teeth are different from the shells and other materials in the surf, so they are often found by themselves.

 

 

This one is fairly obvious.  Notice that this tooth has more of a "T" shape, due to the attached gum.  Also, notice that it is larger than all of the other material around it.  Again, the sharks teeth are different from shells, (in surface texture and weight), and so are commonly found not with but away from shells of similar size.

 

 

This one is a little tougher.  Actually, I can't even find it, but there is one or more in here somewhere.  A version of these images at higher resolution can be found at www.outsideaudio.com.
