Water-worn Rock (Non-Fossil) - Not a fossil; geological rock (water-worn pebble/cobble)

Water-worn Rock (Non-Fossil) (Indeterminate / Modern Alluvial)

Unidentified Fossilized Fragment / Pebble - The provided image shows a small, smooth, water-worn object resting on a dark surface. Due to the extreme distance, low resolution, lack of diagnostic morphological features, and lighting conditions, it is not possible to reliably determine whether this object is a true fossil (such as a worn bone fragment, tooth, or heavily abraded invertebrate shell), a mineral concretion, or simply an ordinary water-tumbled rock (pebble or quartz). No biological structures, cellular patterns, or recognizable skeletal elements can be verified from the image.

Unidentified Fossilized Fragment / Pebble (Unknown (cannot be determined without context or analysis))

Unidentified dark fragment or possible geological rock/mineral - Uncertain / Likely an igneous rock or non-fossiliferous mineral fragment (appearing to be vesicular basalt or scoria based on visual texture, though image resolution is too low for definitive identification)
