State by State
- Specimen Number
Fractured block of massive, uniform, cream-colored limestone with irregular brown inclusions. Appears grainy in close-up as a clast-supported carbonate sand composed mostly of shell fragments, most of which are elongated. A grainstone. Many detrital fossil fragments possibly with some minor silicate sand. Resembles the famous nearby Salem Limestone in texture and composition. Nowhere it visibly oolitic.
Sedimentary. Limestone. Grainstone.

Unknown. Shallow seas with currents to form carbonate sandstone. A search for the similar "Salem Limestone" results in: "cross-bedded calcarenite.... Individual grains are mostly microfossils ..."

This is the pavilion's stand-in for the Salem Limestone, which was intensively quarried and shipped via railroad to produce much of the architectural dimension stone in the United States.
