This is a wonderful plate of crinoids from the famous Mississippian layers near Crawfordsville, Indiana. There are FIVE crinoids of FIVE different types on this plate. An excellent Macrocrinus mundulus is positioned in the upper-middle of the slab. This camerate crinoid has a very robust cup composed of many plates and long, unbranching, biserial arms. The arms are complete to the very tips, and the fine pinnulation is beautifully displayed. The slender anal tube extends above the tops of the arms, and a small stem is still tightly attached to the cup. Directly under the Macrocrinus is a beautiful Histocrinus coreyi, a relatively uncommon species of crinoid from this location. The detail of the fossil is superb. The crinoid has great color and contrast. The plate structure is excellent, and the long uniserial arms are somewhat splayed and display the heavy pinnules. A long stem is still attached to the cup. Touching the stem of the Histocrinus is a very pretty Cyathocrinites sp. This inadunate crinoid has a cup comprised of large, stellate plates. This crinoid is preserved in a ''starburst'' position and is quite aesthetic. There are also two other small crinoids on the plate. All of the fossils are quite 3-dimensional and are totally natural to the plate - none of the specimens have been composited or ''added on''. The echinoderms are well presented on the rectangular, unbroken plate of siltstone. This is a very collectible plate of crinoids from this renowned site.
This fossil was collected and obtained legally, and is also being sold legally.
