Peace River finds

[PeaceRiverHistory]

Hello would anybody be able to assist me with identifying the genus or species of these? Or if they’re event porpoise teeth? 
 

There is also an additional tooth that I am not sure on, definitely herbivore but that’s all I know .

3 teeth that I believe are porpoise but would love a species from.

 

 

 

 

Horse or bison? Apologies for bad pic of chewing surface it was oddly difficult to photograph.

Welcome to the Fossil Forum... a great place for anyone who hunts he Peace River or anywhere else. 

As you surmise, the 1sr 3 teeth are dolphin and the last, a land mammal tooth is either Bison or modern cow (BOS).

On the Bovid tooth or any land mammal , the most important photo and measurement is the length of the chewing surface... The one measurement , you did not give us for this tooth...
