Cindy, Those sound like a perfect description of snapping turtle eggs. Normally they would be buried in a shallow nest on land, but it sounds like for some reason, a turtle made a mistake. Could be that it got disturbed while laying and went back to the water before it was really finished, or something like that.
If you still have the eggs, you could try burying them in a sandy and sunny spot and waiting to see what happens. Tom
The eggs we saw are perfectly round spherical shape about 1 inch to 1.25 inches in diameter, white in color and they were rather soft. You could easily dent the “shell” with your finger by holding it too tightly. I did not take a picture of them. They were not firmly sitting on the bottom but rather moving along the lake bottom with the flow of the waves. They are easily seen from the dock or standing on the shore or in the water. Cindy
