These were found near the same area of southwest Texas as my previous posted rock...any ideas on these as well? They are both really odd shaped in person like shellfish of some sort that petrified.View attachment 1548300View attachment 1548302View attachment 1548300View attachment 1548305
Hard to tell. Silica-based for sure. Chalcedony?












i'm assuming this is just a white quartz. What makes it so bizarre is I live in the mountains of western North Carolina and I have nothing but Boulder after Boulder after rock after rock. Some the size of a car. They are all dark colors. This thing stands out from a mile away and I don't know where it came from as it doesn't match anything else in the creek. Anything special about it? I have more pics if needed but I doubt it
