Lmshoemaker Posted July 14, 2012 Share Posted July 14, 2012 (edited) I heard that the stem, when nearest to the calyx will start to variate in size, with alternating larger and smaller stem plates; is this true? Here is an example: http://weekstrilobit...erocrinites.htm The one on top here appears to have that pattern, I can't tell with the one below.

erose Posted July 15, 2012 Share Posted July 15, 2012 (edited) Maybe for some genera but crinoid stem shapes and configurations come in a tremendous variety of forms. But I love the example. Edited July 15, 2012 by erose Link to comment Share on other sites More sharing options...
thanatocoenosis Posted July 16, 2012 Share Posted July 16, 2012 If you check the Treatise, part T-2 vol. 1, there is an abundance on morphology of stems and everything else. IIRC, there are 8 different basic configurations of stem types... ??? 2012 NCAA Collegiate Round Ball Champs; and in '98, '96, '78, 58, '51, '49, and '48, too.
