Mostly corals/sponges, but may include some death plates. Just need to cut them open to find out. Should make some great cabs, tumbles or display slabs from these. Scale said 5lbs, but dunno if that is correct. Pieces range from 1.5” to just over 3”. I can add some smaller pieces to increase the weight but could not fit in more that would yield at least 2 cabs.
As near as I can tell, they are a mix of the below.
Halycites chain coral Favosites (honeycomb coral) and the Halysites (chain coral)
Tabulate corals (order Tabulata) make their first appearance in the early Ordovician. Tabulate corals were colonial, building closely packed calcite tubes (corallites) with horizontal dividers (tabulae). Favositid corallites are packed into a honeycomb-like structure. Favositid corals were important reef builders during the Silurian and Devonian. Halysitids corallites were linked like chains and are often referred to as chain corals. Halysites was an important reef building coral during the Silurian.
Rugose corals make their first appearance in the mid-Ordovician. Rugose corals are solitary, such as Horn Coral, or colonial. Corallites of rugose corals are subdivided by vertical walls (septa). The polyp lived in the cup-shaped top of the corallite and grew upwards. Solitary rugose corals are called horn corals. Hexagonaria is a colonial rugose coral that was an important reef builder during the Devonian. Tabulate and Rugose corals met with extinction in the Permian.
Most are locally considered coral nodules, the base from which the living coral grew upward. They are often Oolictic and sometimes contain crystals or agates. Some are small coral branches/polyps, which are usually Oolictic.
Photographed with a combo of natural and LED light, wet (some are partially dry). Only posting some pics here, but there are many on Flickr. Thanks for looking. Please let me know if you have any questions.
