Extraordinary Common Teeth

[siteseer]

Hi Will,

 

Yeah, sometimes a camera can't pick up a color difference or an effect at an angle that is visible to the naked eye.  Those Hallencourt teeth are so fragile and often found chipped.  Years ago, a friend sent me a sample of what is found there.

 

Happy Holidays,

 

Jess

That’s a beauty Tom . You do find some nice fossil. 
 

stay safe Bobby 

 

Hi Bobby,

 

Yeah, he's found the best megalodon and the best hastalis I've ever seen from the area.

Scarcely seen from Indonesia.  With the of the thousands and thousands of Megs coming out of the country, I’ve only seen a couple Great Whites.

 

Carcharodon carcharias 

Early Pliocene

Cidolog

West Java, Indonesia 

[Bails]

Here are two C. angustiden and a C. chubutensis/early C. Megalodon with a nice blue crown and brown root that I found in Charleston, South Carolina!

[Chimera]

Otodus (Carcharocles) auriculatus (Blainville, 1818)

North Carolina, USA

Castle Hayne Fm, Lutetian, Eocene

height : 6.1 cm

[Notidanodon]

Here’s a nice one from Hawaii, off the coast at oahu, a galeocerdo Cuvier

Here's an unusual posterior tooth.  It's a Carcharocles (or Otodus as the trend seems to be now) specimen that would be called C. chubutensis or early C. megalodon as Bails noted for one of his teeth.  It's unusual because it's from Bakersfield, California but not the Sharktooth Hill Bonebed.  It came out of the Lower Round Mountain Silt, which is a couple of million years older, and from a site around the Kern River.  It's an old collection piece found in the 1960's.  It might be overlooked as having a broken-off lateral cusplet but a closer look reveals that it had just one fully-developed one and not even a hint of one on the opposite side,

 

It measures just over 1 1/8 inches wide.

That is an awesome tooth!

Gorgeous !!! Thanks for sharing.  It reminds me a little of this Meg from Peace River, Zolfo Springs. Note the cusp is also on the inside of the curve...

Yes Jack, you have found his east coast brother.

Wow! Stunning tooth!!

[PrehistoricWonders]

Here’s one I got today. C. Megalodon tooth with pretty much all the serrations! This tooth is from Florida and measures 2.92” long.

In an attempt to reel in Marcel again, here's a cool little tooth, a juvenile great white from the Pliocene of Chile (Atacama Desert).  It's 9/16 of an inch (14mm) with irregular serrations as some juvenile great white teeth tend to bear.

Very interesting tooth JEss. Is it yours?

Oh yeah.  I got it maybe 5-10 years ago.

[siteseer]

Here's a great white from the Pliocene of Ridgeville, SC.  It's unusual for its white/off-white colored crown.  It measures 2 1/4 inches (57mm) long. 

[fossilselachian]

Very nice Jess.

Here is a not so common tooth from Texas

Carcharodon carcharias

Late Pleistocene

Beaumont Formation

Galveston, TX

What an awesome thread, there are a lot of teeth on here I am jealous of!

My addition to keep it going....

 

Otodus obliquus

Likely Morocco but I have no details

I have more O. obliquus teeth than this, but these are the largest 

 

 

 

 

 

 

Palaeocarcharodon orientalis

Khouribga, Morocco

5o million years old

These two are in pristine condition, photos don't do them justice

Otodus megalodon

No info on a find location or age

 

[Gareth_]

Enchodus libyus (not 100% on the species, but likely)

I've got a few more common fossils from the pointy end of prehistoric animals but this will do for now

French and Moroccan meg bit beat up but I like the colours the French one has a sort of blue tinge

 

Hi Will,

 

I have a French tooth with very similar, if not identical, coloring.  Mine is from Savigne, Touraine.

 

Happy Holidays,

Lovely tooth Jess! Happy holidays to you too

Here's a Carcharocles (Otodus) tooth (1 5/16 inches or 33mm) that seems to challenge how we try to put specific names on fossils in general and fossil teeth in particular.  It doesn't have lateral cusplets but it was collected from the late Oligocene Chandler Bridge Formation, Summerville, South Carolina.  You would expect at least noticeable cusplets on a Carcharocles tooth from that time (the chronospecies, C. angustidens, (less prominent than on an auriculatus/sokolowi tooth and more prominent than on a chubutensis tooth).  The bourlette is largely worn away so someone might say it's a great white tooth (Carcharodon carcharias) but I don't think teeth from the early Pliocene or more recent have been found there.  I think it's an example of something that is sometimes found - a tooth that sort of previews what the "normal" form is going to be for the animal in the distant future. 

 

There's always a range in general form (smaller/larger, narrower/wider, thicker/thinner) and no tooth deviating from the norm is necessarily an indicator of where the evolution of the animal is heading nor an indicator of what the optimum form is or should be.  It's just a natural variation.  It's something like the red-haired kid from parents that both have brown hair or the tall kid from short parents.  This tooth just happens to show what a Carcharocles lower is going to look like in 10-15 million years.

Here's a Carcharocles tooth from the Oligocene of Say-Utias, Mangyshlak, Kazakhstan.  I've seen alternate spellings of the locality, Say-Utias (e.g. Sai-Utjas) but none of them come up in a search so I assume it's a small town or spot just locally known.  This tooth is just over 2 1/8 inches (56mm) along the mesial slant.  It was sent to me by a friend because he knew I liked oddball teeth.  Check out the serrations of the lateral cusplets.  They're spikier than normally seen especially for an Oligocene tooth.  Weird serrations are more often seen in Eocene teeth.  It made me think this tooth might be older but the locality is known for Oligocene teeth and not those typical of the Eocene.

 

Carcharocles teeth from the Oligocene of Kazakhstan are at least uncommon.  I show it here because it's an oddball of a species that is common elsewhere.  They have been identified as C. angustidens or C. turgidus or turgidus is added as a subspecies of angustidens.  This tooth seems rather thick at the lingual protuberance for a C. angustidens tooth of its size but maybe the site is early Oligocene in age.
