Fossilized shark teeth come from several different types of ancient sharks, but the most common came from tiger, mako, sand, otodus and lamna sharks. If a shark loses a tooth while biting into something, another tooth from the second row would replace the missing tooth within four minutes.  Thus, many teeth were lost over the lifetime of a shark. 

A geode is any stone that is hollow with some sort of mineral or crystal on the inside.  A geode with a hollow cavity is one of nature’s most spectacular works of art.  No two geodes will look exactly alike and until opened, it is a mystery as to what is inside.
