Help ID fossil Calvert Cliffs

[willobea]

Found this little piece yesterday, I have some whale teeth, but may be a Claw core from an alligator? Found in my secret place along Calvert Cliffs. Thanks for any help on this one!

Looks clawish to Me, but I am not well versed with claws. It does not resemble the whale teeth I am familiar with.

PS Nice shark teeth!

 

[Harry Pristis]

Not anything I recognize.  Looks more avian than reptilian . . . NOT a crocodilian.  See the variety of claw cores/unguals in my Gallery album, BONES.

[Troodon]

Incisor from a peccary?

 

Collected at Calvert

Thank you! I have so many finds I will start sharing! I think Troodon is correct in being a peccary incisor after looking up some photos.

Nice finds!!!

[JMUFossil]

Great find!

 

Trodon helped me id a peccary tooth from the cliffs as well. Very cool that we are able to find terrestrial fossils in a Miocene marine environment.

Thank you. I posted a pic on my New Member page of some of my best finds! Oh it's great to have quick access to information now! I also have a peccary with blueish enamel. I am going to try and get photos of all my things soon and put them in the gallery.

Canine from a peccary?  Not like any of my examples.  This proposal caused me to realize that this curved

object is probably a beach-polished ROOT from a still unidentified canine.  I was trying to make this the enamel

end of a tooth.  I should have realized that canine crowns of familiar animals are not grooved like this, while roots may be.

[fossiling]

the rightmost tooth is a mako. the leftmost one is a hemipristis serra. they are both sharks and are common finds around the world.

p.s. I am a novice to other fossils, but I can recongize shark teeth fairly quickly and accurately

[Al Dente]

Looks similar to a Squalodon incisor.

[Optimist]

Here are some of my squaladon incisors found in Calvert Cliffs,  There is some resemblance.  

 

[ynot]

I agree it looks like a whale tooth root- no crown.

Can you post a picture of the side of the tooth that is on the inside of the curve? That surface will settle if it is a peccary canine or some kind of whale tooth.

[Boesse]

It's not a Squalodon tooth, and it's definitely not a claw since it is made out of enamel and dentine (claw cores are bone). I really doubt this is a whale tooth; if it were 1/3 the size, it would be a close match for the platanistid dolphin Araeodelphis natator - but there aren't any known odontocetes with teeth that sized that are curved like that. My vote goes for land mammal. Also, if the posterior side (inside of the curve) has any sort of a flat facet that would give it a semi triangular cross section, that's a dead giveaway that it's not from a cetacean.

[Boneheadz]

could be a croc tooth but not sure

 

[Boneheadz]

also love the mako!

 

[fifbrindacier]

I agree with the ID OF Mako thooth on the right.

[MarcoSr]

The genus for hastalis is now Carcharodon.  So the tooth on the left (Carcharodon hastalis) is a great white (researchers prefer white shark as the common name) tooth and not a mako tooth.

Hi Marco,

 

Have you got a reference to the reassignment of I. hastalis to Carcharodon?  Thanks!

Don, here's the paper, Ehret et al. 2012: http://onlinelibrary.wiley.com/doi/10.1111/j.1475-4983.2012.01201.x/abstract

Same reference as Boesse has already posted.  However, irrespective of what the researchers call hastalis, if you compare hastalis teeth to the teeth of the extant great white and the two extant makos, shortfin and longfin, you'll see why it makes sense that hastalis is a great white ancestor and not a mako.

Sorry to have disappeared from the site! I will take another photo and see if we can get a confirmation of land mammal. The other two I find regularly around here, I thought it was a Mako too... ? I was just showing my best pieces haul for that particular hunt.

Here are underside and top and inside photos.
