Lasiocrinus scoparius CLASS - Crinoidea ORDER - Disparida FAMILY - Cyathocrinidae GENUS/SPECIES - Lasiocrinus scoparius ROCK UNIT - Coeymans Formation, Helderberg Group AGE - Early Devonian (400 million years old) LOCALITY - Jerusalem Hill, Herkimer Co., New York, USA The delicate specimens were found in a shaley bed within the crinoid-rich limestones of the Coeymans Formation. The billions of fragmented crinoid stems and arms that make up most of the Coeymans Formation indicate shallow, turbulent sea floor conditions. In such a setting, these specimens from Jerusalem Hill must have been buried alive or immediately after death to keep the skeletons intact. CU 6548
