We have been able to purchase some exceptionally nice Lamna species teeth as well as Megalodon teeth while here in Tucson. The latter are very nice indeed in that they vary considerably in color rather then being just the run-of-the-mill black. For the Lamna teeth one must always look for the cusps on either side of the main tooth. If the cusps are missing the tooth isn't as valuable.
The Lamna teeth are almost always white to a light tan in color and are very sharp!
The Megalodon teeth are the right in these pictures and the Lamna are directly above on the left.
Below, on the left are teeth from the mosasaur species globidens. These were shell-crushing aquatic reptiles that died out 65 million years ago. Most of you are familiar with the more common mosasaur teeth we sell, but these are entirely different and much rarer.
Below on the right are ammonites from Madagascar. These have been polished to expose the sutures that marked the separations between the internal air spaces the animal used for buoyancy.
Finally, we have also been acquiring some minerals specimens, and for the first time we have purchased some polished quartz crystals about 1.5" to 2" long. These are pictured below.
