Submitter notes: A rare and sought after stemless blastoid that evolved to lay on the substrate. There is only one species worldwide for the genus Eleutherocrinus. This view shows the long ambulacra of this blastoid's theca. The specimen on the left measures 14mm X 9mm. The middle specimen measures 17mm X 12mm, and the largest specimen on the right measures 19mm X 14.5mm.

Submitter notes: It is not uncommon for Greenops specimens to have their pygidium tucked under. A little extra cleaning will expose what first appears to be a tail-less specimen. This trilobite is 21mm wide and is approximately 34mm long if you count the enrolled tail.

Submitter notes: This is a not too good example of this rare and unusual blastoid. Eleutherocrinus cassedayi from the Hungry Hollow formation at the 'tileyard' at Thedford, Ontario, Canada. The blastoid is 17 mm long and 9 mm wide.Better examples are shown on this website but these are so rare that all examples should be looked at and any partial collected.It is believed that these blastoids were not attached as adults and able to move independently.
