There is a crown fragment near the margin of the plate (pic 5) and a couple of crinoid stems. My question is: Is the circular structure in the middle of the plate a flattened (compressed) lobolite? For comparison, I show an unquestionable lobolite of Scyphocrinites (Erfoud area) in pics 6 - 8. The circular structure on the plate has about the same size (width: 9 cm). If the structure is normal matrix, I wonder why the crinoid stems lie outside around the stru
