Sea Monster Mystery!

I have many more photos, but this is enough to tell the story of these strange tracks we came upon, on a deserted section of beach.

These huge claw sets of tracks came out of the ocean.  The were in sets of 4 and about 10 feet apart.  The tracks were pointing perpendicular to the direction of travel.

The came out of the ocean, went down the beach for 30 or 50 yards or so, and then went right back into the ocean.  There were no drag marks like a turtle or sea lion would make.  And the thing was very heavy, judging by how the sand was pushed in the tracks.

Anyone know what these are?

  

We have these horses that wander around town without anyone watching over them.  They eat the grass in the parks and plazas, eat trash out of the trash recepticles, seaweed on the beach, etc.   They poop all over the place in the streets and sidewalks and plaza.  Sometimes we see donkeys wandering around too.  Nobody else seems to notice.  I caught this horse raiding the trash around 10 p.m. one night, right on a main busy street.  I thought it was just the many stray dogs scatering the trash all over at night. This horse has the high trash all to himself.
