Shark Tooth Fossil
from Morocco
Since shark skeletons are composed of cartilage instead of
bone, often the only parts of the shark to survive as fossils are
teeth. Fossil shark teeth date back hundreds of millions of
years. This specimen is 1 to 1.5 inches in length.
Odotus
Obliquus Approx. 50 Million Years Old
from Morocco
A tooth becomes a fossil when it is buried in sediment (or other material) soon after being lost from a shark's mouth. The sediment precludes oxygen and harmful bacteria from reaching the tooth and destroying it, while it is replaced or permeated with stony material. The general fossilization process varies greatly depending on the exact situation, and
the tooth takes on the color of the
surrounding rock. $4.00 each
