Carcharodon carcharias (Neonate) Pisco Formation, Departamento de Arequipa, Sitio Sacaco, Peru Right Upper Lateral A small tooth from a young-of-the-year great white (~ 1.5 m / 5 ft total length). Teeth of these very young individuals are narrower than adult teeth, and possess lateral "cusplets" - features that aid in their piscivorous (fish-dominated) diet. -

Carcharodon carcharias (Young Juvenile) Pisco Formation, Departamento de Arequipa, Sitio Sacaco, Peru 2nd? Left Upper Anterior A small tooth from a very young great white (< 2 m / 7 ft total length). Teeth of these very young individuals are narrower than adult teeth, and can possess lateral "cusplets" - features that aid in their piscivorous (fish-dominated) diet. -

Carcharodon carcharias (Neonate) Pisco Formation, Departamento de Arequipa, Sitio Sacaco, Peru 3rd Right Upper (Intermediate) A small tooth from a newborn great white shark (~ 1.5 m / 5 ft total length). This is a rare intermediate tooth which is mesially-slanted, and reduced in size relative to adjacent teeth. The smaller size of the 3rd upper anterior is an adaptation unique to the dentitions of Lamniforms, thought to concentrate the bite force in the first two upper anteriors. -
Identification Teeth of Carcharodon carcharias may be identified by triangular crowns with no nutrient groove in the root, no lingual dental band ("bourlette"), and irregular triangular serrations on the edges. Teeth of neonatal individuals (newborn/young of the year) possess small lateral "cusplets," with a deep "V" profile made by the root lobes, and are more narrow than adult teeth1. This narrow tooth form with cusplets is suited for the great white's piscivorous (fish-dominated) diet at a young age. Comments This is an exceptional upper right lateral tooth from a newborn or

Cool bichrome great white tooth from the Early Pliocene of Southern Peru. Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit by the BHI. -

Lower tooth from an early great white (Early Pliocene). Juvenile teeth are narrower than those of adults, more suited to a piscivorous (fish-eating) diet. Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit by the BHI. -

One of the most coveted teeth due to the great white's popularity. Being one of my favorite animals, I knew I had to get a nice one eventually. This one in particular is special. Besides being in superb condition, this tooth has a bite mark on the root: three parallel grooves on the labial side of the root gouged by serrations. Bite marks on teeth are uncommon, and a neat feature on this already sweet tooth. This tooth is from the desert of northern Chile. Fossils from Chile are now illegal to export, so as an ethical collector you need to make sure that any Chilean fossils you are interes -

White sharks used to have smooth-edged teeth. They eventually evolved serrations as their diets transitioned to marine mammals from fish. This shark was a transitional form between the smooth-edged predecessors and the modern fully-serrated great white. The serrations on this tooth are not worn-down. C. hubbelli serrations are naturally finer, typically decrease in size towards the tip, and are oriented towards the tip. This tooth is from the desert of northern Chile. Fossils from Chile are now illegal to export, so as an ethical collector you need to make sure that any Chilean fossils you ar -

Nice color on this early great white shark tooth (Early Pliocene). This one comes from the desert of southern Peru, where a long period of sand blasting has smoothed this tooth to a near-polish, all but erasing the serrations. Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit by the BHI. -
Identification Teeth of Carcharodon carcharias may be identified by erect, triangular crowns with no nutrient groove in the root, no lingual dental band ("bourlette"), and irregular triangular serrations on the edges. Comments This tooth is Early Pliocene in age, which is about as old as great white shark fossils get. Fossils are now illegal to export from Peru. This tooth was collected by the BHI during a series of expeditions to Peru 1985-1990 under a government permit.

Identification Teeth of Carcharodon carcharias may be identified by erect, triangular crowns with no nutrient groove in the root, no lingual dental band ("bourlette"), and irregular triangular serrations on the edges. Comments This tooth has a self-inflicted bite mark in the form of three parallel linear gouges in the labial face of the root made by serrations of another tooth.

Identification Teeth of Carcharodon carcharias may be identified by erect, triangular crowns with no nutrient groove in the root, no lingual dental band ("bourlette"), and irregular triangular serrations on the edges. Teeth of juveniles are smaller in size, and are comparatively narrower than adult teeth, suited for a piscivorous diet. Comments This tooth is Early Pliocene in age, which is about as old as great white shark fossils get. Fossils are now illegal to export from Peru. This tooth was collected by the BHI during a series of expeditions to Peru 1985-1990 under a go

Great whites didn't start out "great." As young, small animals, they had narrower teeth suited for grasping slippery fish. As they age, the teeth broaden as their diet transitions to marine mammals. This small tooth measures ~ 1" on the slant and comes from the Early Pliocene of the Pisco formation in southern Peru. This is about as old as great white teeth get, they evolved from C. hubbelli near the start of the Pliocene (~ 5.3 Ma). Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit. As ethical collectors, please do -

Some rare colors on this tooth! While it looks like Bone Valley, this great white actually comes from southern Peru (Pisco formation, Early Pliocene). This is about as old as GW teeth get - the modern species evolved from C. hubbelli around the Early Pliocene (~ 5 million years ago). Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit. As ethical collectors, please do your due diligence to verify any Peruvian fossils you're interested in were exported prior to the ban. I respect any country's decision to protect their natural -

I ran out of room in the other display, so I split the collection into extinct/extant species. I probably still need another riker! For scale, the big great white tooth is about 2 1/4" slant height. In red are species that are endangered or critically endangered. The only teeth I regret having are the modern Makos, I had gotten them for comparative reasons (both are anterior, left is upper, right is lower). The fossil Mako is actually an I. desori (a big one!), but I included it since it's so morphologically similar to the extant species, and a few people would say they're synonymo -
