A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

The dimensions given are for the largest specimen. The block is 11.5 com at it's widest point by 10 cm and 2 cm deep. Most of the of the other species ascribed to this genus in Morocco are now considered junior synonyms. See https://link.springer.com/chapter/10.1007%2F978-3-319-04364-7_199 Notice that they are all aligned in one direction as they were buried by a mudflow sweeping in from the continent. The arms, bodies and stems are all pretty much aligned. This seems to have occurred fairly regularly in this area at this time. Also notice younger, smaller specimens have fewer plates and arms.

Large plate of Eocrinoid Ascocystites, needs a closer look
Biotalker posted a topic in Is It Real? How to Recognize Fossil Fabrications
There is a plate of 30 or so of the ascocystites being offered for a rather princely sum. Stated as collected near Kaid Errami, Morocco. Here is the entire plate and a close up. It looks un-fossil-like to me. Seems unlikely, but could they be real?- 12 replies
