A spectacular, 10.5" plate of twelve detailed fossil crinoids and a gastropod of the species Platyceras acutirostre (#93), collected from Crawfordsville, Indiana. These fossils have been microscopically prepared using air abrasives, revealing their intricate details and three dimensional preservation. It is believed that crinoids from the Ramp Creek Limestone were buried in sediment from nearby deltas during storms. The resulting siltstone deposits are soft enough that fossils can be extracted in exquisite, three-dimensional relief.Source: https://www.fossilera.com/fossils/10-5-fossil-crinoid-plate-six-species-crawfordsville-indiana -- source link
