Whale teeth(?)

[ynot]

Hey hi Folks,

I was wanting to see if I could get a better idea of the identity of these teeth. scale is in inches.

They have a faint carinae (cutting edge) that has weak serrations at the lower part of the edge.This feature is on the inside of the curve of the tooth, but not centered. It is more apparent on the darker crown. The darker tooth also has a second serrated carinae that splits at the base (forming an upside down "Y")

 

Thanks for Y'All's knowledge and help.

Hi, 

 

Based off the size they could be porpoise teeth, I wouldn't have thought dolphin as I've always presumed their teeth to be quite thin. However, the smaller tooth with the yellow crown reminds a bit of a pinniped like a seal, although I'm sure there's someone who'll be able to tell better.

"Porpoise" has a very specific meaning (Phocoenidae). Phocoenids do not have a middle Miocene fossil record, and their teeth are tiny and conical or have spatulate crowns. These are indeterminate odontocete teeth, probably from some kind of a "kentriodontid".

@Boesse can I get Your opinion on these?

Thank You.

 

Whoops, I was to inpatient.

Thanks again!
