Physical properties

Fine-grained, foliated sedimentary rock. Hardness: 2-3 (Mohs). Color: Grey, greenish-grey. Contains a linear fossil impression, likely a plant stem or trace fossil.

Formation & geological history

Formed in quiet environments like lakes or deep oceans through compaction of clay, mud, and silt. Fossils are preserved when organisms or traces are buried quickly in these fine sediments.

Uses & applications

Collecting, educational purposes, paleontology studies.

Geological facts

Shale is the most common sedimentary rock. The fine grain size allows for excellent preservation of delicate fossils.

Field identification & locations

Identified by its fine grain, tendency to split into thin layers (fissility), and presence of fossil impressions. Common in sedimentary basins worldwide.
