Micro teeth, Hemipristis?, Enchodus?,Pharangeal?

[Lone Hunter]

Cretaceous Eagle Ford,   #1 I know it's worn and broken root but both edges are serrated,  Hemipristis?  #2 Both Enchodus or the smaller one possible Xiphactinus? #3  Had hard time getting details, assuming it's some kind of tooth,  bony fish? Ptychodus?

Too old to be Hemipristis. Squalicorax is more likely if there are serrations.

I can’t make out much detail on the smaller one but the larger one is a piece of shark tooth. The enamel folds make me think it could be Scapanorhynchus.
