BOX OF FOSSIL CRINOID STEMS
  
320 million years old
   
San Baba Ranch, Texas, USA
  
A collection of about 50 pieces of fossil crinoid stem in a plastic box with a clear lid. They are from an old collection.
    

Crinoids (also called sea lilies) look like plants but they are marine animals related to starfish and sea urchins. Most species were attached to the seafloor by a stalk but some were free-swimming. The mouth was surrounded by numerous feeding arms. Pieces of the stalk, or stem, is usually all that remains of them.
    
Crinoids are still living today but were much more numerous in the prehistoric past.​​​​​​​
