Jaw Fossil Identification Help

Recommended Posts

Hello,

 

I found several of these at an estate sale in Southern California.  They were in a rusted tin can and found them interesting.  This was an estate from a mineral collector and found the tin among thousands of mineral specimens that were for sale. First I thought they were some kind of mineral, but after washing them (they were covered in rust from the can), they looked to me more like small jaws with teeth. I have been looking online for weeks and can't find anything close to them. Any help would be greatly appreciated.  Thank you in advance.

Looks like some species of Carp - pharyngeal teeth.  Possibly Black Carp.

Neat.

Hi Tim,

 

I agree.  They have been identified as Mylocheilus robustus.  There have been threads about these jaws before.  Check out these threads from a few years ago:

Thanks for bringing those posts back to light, Jess! :) 

And for the further ID information. 

Why I love this site so much. ;) 

Best regards,

Excellent, good images, also !
I'm glad to see this. :)
I want just to complete the topic with these documents (although some of the pictures are not so good in the copies), but the description of species are relevant, covering the genera mentioned in the above threads :
