Northern Sharks Posted March 1, 2020 Share Posted March 1, 2020 A friend of mine purchased a collection recently with bits and pieces from several Canadian and American locations, but a lot of specimens had no labels, including this crinoid. Any help with ID and possible location is appreciated. The entire crinoid measures between 4-5cm. It was identified on FB fairly confidently by a well known collector/dealer as Apographiocrinus typicalis from the LaSalle limestone of Pontiac, Illinois (Pennsylvanian age). Not that I don't trust that person, but second opinions never hurt. Thanks in advance. 2 There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...
