Submitter notes: Quality single specimen trilobites’, found enrolled or prone, are rare for the formation. The Hungry Hollow member was a high energy environment which made preservation of complete specimens quite rare. Finding more than one trilobite genus on a slab is even rarer. From left to right the specimens measure 23.5mm X 18mm, 30mm X 18mm, and 32mm X 23mm. The second Basidechenella on the right of the Eldredgeops is upside down.

Submitter notes: The 1958 checklist by Stumm & Wright lists 9 different Dolatocrinus species. This genus exhibits a great deal of plate variation for any given species. With this in mind, Kesling & Mintz (1963) synonymies nine species into three; D. bulbaceous, D. liratus, and D. tridactylus are the species from the Hungry Hollow member listed in the order of their abundance in the formation; however, all are very rare. The three specimens of D. liratus in the photo show top, side, and bottom views. They all measure 17mm in diameter and average 15mm in height.

Submitter notes: Like the genus Dolatocrinus, Megistocrinus has great plate ornamentation variability which can make classification to the species level difficult. There are probably only 2 or 3 species in the Hungry Hollow member. Loose plates of Megistocrinus are common in the formation and even partial specimens should be collected due to the rarity of whole calyxes. This specimen is 29mm in diameter and 19mm high. This photo is of the tegmen(top)view.
