Slab of algal mound flank facies of Worland Limestone

Slab of limestone from the flank of a Worland Limestone algal mound.
Most of the coarse particles are broken algal plates and pieces of algal
limestone and micritic skeletal limestone (intraclasts) that were eroded
from the mound and redeposited near by. There are also scattered
brachiopods, gastropods, ostracodes, and echinoderm fragments. The
various kinds of grains are separated by stylolitic (solutional) contacts
where reddish-brown iron oxides are concentrated. A weathered
surface shows near the edge of the slab at the far right.
