Crinoids

 

Fossils from Holzmaden, Germany are highly desired for their exceptional preservation. Also appealing is the richly colored black-brown shale matrix of this locality. Remains of animals from the warm, shallow Jurassic seas in the region now known as Germany reflect the warm environment of the Earth 180 – 170 million years ago. Subtly shimmering pyrite inclusions impart a glowing presence to these fossilized animals, which are plant-like in appearance. These individuals would have floated on a piece of driftwood (seen preserved on the lower part of the plate), filter-feeding in the warm Jurassic sea.
