Shocking Shark Teeth from the myFOSSIL app 5 years, 3 months ago 5 years, 3 months ago5 years, 3 months agoWhat a difference in preservation between these two!
Found on a dredge spoil island on the Cape Fear river near Wilmington, NC. #fossil
What causes that kind of discrepancy?
Both teeth have been weathered as a result of being transported in a river. As the teeth are transported by the water they are worn down and their edges become smoothed out. If you look closely at the tooth on the right, you’ll notice that it has faint serrations that have been worn down. The tooth on the left has completely lost the enamel that covers the crown of the tooth. This tends to happen when a tooth dries out in the sun, the enamel will begin to flake off. Both teeth are likely the same species (Carcharocles auriculates), which is an Eocene ancestor of Megalodon.
You can imagine it working like sand paper.
@Denise-porcello I have no idea! Shark people, @jeanette-pirlo or @vperez, any thoughts?

Amazing! Thanks Victor!
