Description

Mesozoic Echinoderm, Hardouinia fossil replica. Fossil measures approximately 4 centimeters or 1.25 inch. This fossil replica represents an ancient sea urchin that crawled along the seafloor, feeding on algae. Although they are rarely preserved, echinoderms that looked like this had long spines like the sea urchins of today. This fossil is great for learning about paleontology and fossil preservation. You can also bury it in the sand and make your own fossil hunt.
