Carcharodón Tooth - White Shark Ancestors in Peninsula Valdes


The ancestor of the white shark also left signs of it existence in Peninsula Valdes, is common to find those signs in beaches and cliffs. Like the majority of sharks fossil registry, the Carcharodon one, is reduced to thousand of jaws and teeth around everywhere, the cartilaginous skeleton of the fish is destroyed normally before it can be fossilized. The teeth, however, are exceptionally hard and they are conserved perfectly. A characteristic of the sharks, is that their teeth are shed continually throughout the fish's lifetime, and new ones are rotated into place on a conveyer belt-like structure, is the explanation for why they lose hundreds of teeth per year.

But for tranquillity of the one of those who usually dive by the gulfs Nuevo and San Jose, these sharks do not exist anymore in Peninsula Valdes. The great white shark (Carcharodon carcharias) is in warm and temperate waters. Its ancestestors lived in this zone million years ago, when the steppe was a forest and in the sea there were turritelas and sand dollars.

If you get to find some fossil, remember that it is not allowed to remove them from the reserve Peninsula Valdes, the best thing to do is to take a photo for the memory and leave it where it was found, by that way you are helping to conserve a human heritage. What you can take with you is all the waste that you could generate during your stay!! =).

If you want to know more about the great white shark, we invite you to see the Web of one of our great guests, Andy Casagrande from National Geographic, with who we shared a pair of weeks during the last season of Orcas.
