A large Moroccan sea lily - Scyphocrinites elegans.
Two large crowns are preserved on the same matrix. It has been 3D cleaned and is a high-quality specimen where the pinnules can be clearly observed. Sea lilies belong to the phylum Echinodermata, along with starfish and sea urchins. Modern sea lilies mainly inhabit the deep sea, but in ancient times, they also lived in shallow seas.

It is said that sea lily specimens from Morocco are cleaned using acid after excavation. Therefore, over time, the matrix and the sea lily itself often turn whitish, discolor, and deteriorate.
To suppress this deterioration, museums and collectors storing Moroccan sea lilies apply a coating treatment. This specimen was also washed, impregnated with a coating agent, and thinly permeated with liquid resin after cleaning.

The specimen weighs over 8.5kg.
