These are vermiculations on a limestone wall in Seneca Caverns, Ohio. Vermiculations are relatively small, worm-like structures composed of fine-grained sediments that occur on some cave ceilings and walls. These features are thought to form as films of water shrink by evaporation, leaving behind concentrations of material along irregular ridges (e.g., see Bojar et al., 2014).
The greenish-colored material is algae growing on the cave walls; the algae is not natural here - it grows due to artificial lighting.
Locality: Seneca Caverns, just south of Flat Rock Quarry & south-southwest of the town of Bellevue, northern Ohio, USA

Macropetalichthys rapheidolabis Norwood & Owen, 1846 - fossil fish in limestone in the Devonian of Ohio, USA.
This fossil fish is a type of placoderm, a group of extinct, mostly predatory fish that existed during the Middle Paleozoic (Silurian and Devonian).
The black material on this specimen is actual bone - most of the bone has been removed by tourists touching the fossil during cave tours. The rest of the specimen is an internal mold.
Classification: Animalia, Chordata, Vertebrata, Placodermi, Petalichthyida, Macropetalichthyidae
Stratigraphy: Columbus Limestone, Middle Devonian
Locality: trailside, Level 2 of Seneca Caverns, just south of Flat Rock Quarry & south-southwest of the town of Bellevue, northern Ohio, USA
