    Overview

    A rare Top Quality, transition GW tooth, Carcharodon hubbelli. An upper jaw anterior tooth. The C. hubbelli serrations are full at the base of the cutting edge, transition to fine serrations at mid crown and disappear towards the tip. This tooth has an excellent tan colored crown and brown root with well pronounced maroon colored gum line. Excellent color. The crown edge starts with two oversized serrations at the base and quickly transforms into "Escheri-like" wavy serrations. An early stage transition form. No repair. Authenticity guaranteed. An exceptional GW transition form!  It will be extremely difficult to locate Carcharodon hubbelli since there is no new supply

    This catalog contains exceptional teeth from an unique form of the Great White shark Transitional Teeth which were recently named as Carcharodon hubbelli (announcement below)**. These teeth are noted for their wide triangular crowns which exhibit little to no serrations along the top one half to one third of the crown. These are thought to be transitional teeth along the evolutionary path between Isurus hastalis (the Big-toothed Mako and precursor to C. carcharias ) and the Great White shark, C. carcharias. These teeth originally thought to represent the Isurus escheri species. Now the I. escheri is thought to be an Atlantic Ocean shark that did not evolve into the Great White shark, C. carcharias. The Chile teeth are thought to represent the true transition to the Great White shark which evolved in the Pacific Ocean. Although the evolutionary path of the Great White shark is being debated, the Chile transition teeth definitely provides strong evidence for the I. hastalis to C. carcharias transition. These are very unique collector's items. These teeth are fairly rare (less than 1 per 100 GW teeth found!) and very showy, making them an excellent addition to your Great White shark tooth collection. Great White transition teeth of this size, color, and quality are rarely seen.Please have a look while the supply lasts. Note - a few of the earliest transition serration patterns ("Escheri type") are included! All teeth are museum to near museum quality teeth. No rest Please oration or repair!

    ** New Identification (Nov. 2012) - Please note that these C. carcharias transition teeth have recently been renamed to C. hubbelli in honor of Gordon Hubbell who found a complete jaw / partial skeleton in Peru. This find also further solidifies popular opinion that the Great White shark is a descendent of the extinct Big-tooth Mako shark (Isurus xiphodon or Isurus hastalis). Hubbell's skeleton was dated to the late Miocene (6.5 MMYA) which puts it as an intermediate between the Big-tooth Mako and the Great White shark which evolves in the Pliocene, approximately 3 MMYA. Please see the BBC report using the link below. The So. American Great White transition teeth are incredible and the Chilean teeth offer exceptional size and quality.
