Are these Iguanodon tooth fragments?

Hi everyone!

 

Are these Iguanodon tooth fragments? They appear to be about a half inch or 13 mm. Sorry the photos aren't clearer, that's what the seller posted.

Broken and tumbled in the waves, not sure they can be identified (even as tooth fragments).

Based on my familiarity with the spit teeth of ceratopsians and hadrosaurs from the American west, I think the labelling is pretty much accurate as an indeterminate ornithopod. These specimens have certainly taken a beating, while the animal was alive, while the tooth was being deposited and following its exposure to the modern elements. Valanginian is a bit too old for Iguanodon proper, but it's likely an iguanodontian of some variety. The genera Barilium and Hypselospinus are known from the Wadhurst Clay, which overlies the Ashdown, and they are exposed in the same area.
