This is a large, 4.3" wide fossil sea urchin of the species Macraster elegans, collected from the Duck Creek Formation of Coryell County, Texas. It is covered in fossils that appear to be worms, however they remain unidentified.

Sea urchins are a type of echinoderm that are still living relatively unchanged today. They live at the bottom of soft ocean floors and have long spines protruding from their central bodies. They move along the bottom of the ocean using many small feet while feeding on various plant and animal matter.
