From the album: Sharks
One of the most coveted teeth due to the great white's popularity. Being one of my favorite animals, I knew I had to get a nice one eventually. This one in particular is special. Besides being in superb condition, this tooth has a bite mark on the root: three parallel grooves on the labial side of the root gouged by serrations. Bite marks on teeth are uncommon, and a neat feature on this already sweet tooth. This tooth is from the desert of northern Chile. Fossils from Chile are now illegal to export, so as an ethical collector you need to make sure that any Chilean fossils you are interested in were exported prior to the ban. -
From the album: Sharks
White sharks used to have smooth-edged teeth. They eventually evolved serrations as their diets transitioned to marine mammals from fish. This shark was a transitional form between the smooth-edged predecessors and the modern fully-serrated great white. The serrations on this tooth are not worn-down. C. hubbelli serrations are naturally finer, typically decrease in size towards the tip, and are oriented towards the tip. This tooth is from the desert of northern Chile. Fossils from Chile are now illegal to export, so as an ethical collector you need to make sure that any Chilean fossils you are interested in were exported prior to the ban. -

A nice upper shark tooth from the six-gill cow shark, from Chile. Possibly from a male. One cusp is missing (far right in first photo).
