Dorudon Skull Clip Keychain

$26.75

mini-dorudon-skull.pngDorudon, which swam the Eocene seas more than thirty million years ago, is thought to have been from the group which gave rise to all modern whales and dolphins (Cetaceans). This carefully researched keychain depicts the impressive skull of Dorudon in great detail. This midpoint in cetacean evolution is exemplified by the nostril opening, which sits halfway in between its original location at the end of the snout, and its present location on the tops of whales' heads.

The mandible and cranium of this articulating keychain are hinged, allowing you to open Dorudon's mouth and see its magnificent teeth! An internal spring causes the jaw to close, demonstrating the interlocking of the incisors, and the shearing action of the premolars and molars.

Comes with a full color diagram. A great educational accessory for fans of paleontology and of marine mammals alike!
