Are we sure they're aquatic or marine in origin? Lots of weird stuff washes down rivers, especially if they run through farmland.
My first thought on this is that it looks very hooflike; I did some checking around and the vascularization seen distally in many hooves (like the second one on this page at horseshoes.com) does look similar.
See attached (also courtesy of horseshoes.com); the 'toe' of the hoof (which may often become overgrown and clawlike if not trimmed or worn away through regular activity) has the right cavity shape when you remove the coffin bone / distal phalanx.
