While digging the area for the new patio, I find a large number of rocks the builder left not to far under the ground. These rocks end up in a pile until it grows large enough to be hauled off to fill in washed out area made by erosion. When I unloaded the rocks I noticed an imprint on the one that looked like some sort of fossil. After consulting my cousin, who is quite the fossil hunter, we came to the conclusion it is a trilobite. He wants to make a casting of it so we can get a better idea about its size and what it looked like.
Here is the image of the rock.
