Footprints are fairly small, could have been a Pterodactyl strike? (thank you autofill on the help with Pterodactyl; Pt and it took care of the rest)

Plot twist: they were my footprints.
I hopped off the porch and went for a walk. After a few steps, the ice was so hard I just walked on top of it, not sinking in, leaving no footprints.
I didn’t realize how weird the remaining prints looked until my husband went out and was like “wtf”.
It’s like with a magician’s trick…I don’t know that I appreciate the explanation as much as I thought I would when I wanted it.
