What is this brown, 4-pointed seed pod?

Question

Please help me to identify the seed. I attach the image of the pod. It was found near the ocean's beach in Boston. I would appreciate any input.

That thing is pretty cool looking - had you not identified it as a plant or pod, I would almost think it could be a very bitey fossilized specimen! — PhasedOut, Mar 17 '17 at 19:43

These are seeds from Trapa natans or "Water Caltrop" or "European Water Chestnut". You're good at finding invasive plant seeds! :)
