This specimen is a fossiliferous limestone. The limestone is grain supported with a predominantly micrite cement matrix. Allochems comprise around 70 percent of slide area. These critieria define the limestone as a packstone. Allochem composition is almost completely bioclast. These estimates and degree of sorting characterize the limestone as a packed biomicrite. Abundant bioclasts include bivalves, based on shell morphology and wave extinction; brachiopods, including shell and spine parts, a variety of echinoderm parts, bryozoans, and likely others. Maximum dimensions for several varieties of bioclast are as follows: bivalve 1.8 mm, brachiopod shell 3 mm, brachiopod spine .6 mm, bryozoan 3 mm, echinoderm-crinoid 1.5 mm. The modal size of maximum dimensions is around .5 to 75 mm. The slide also contains rare, likely authigenic quartz grains with a maximum dimension of .15 mm. Most quartz grains are .04 to .08 mm in size. Collophane fragments, presumably of biological origin are rarely present and have a maximum dimension of .6 mm. There are no appreciable extant voids in this specimen. The well preserved form of most fossils suggests lithification prior to significant compaction. Fossils can be identified in the hand samples with difficulty.
