This bivalve fossil replica looks like a shell you would find at the beach, but it is representative of an organism that lived millions of years ago.

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.

Ammonites grew their shells from calcium carbonate and grew constantly throughout their life span. A relative of octopi and squids today, ammonites swam through the open ocean, preying on smaller marine animals.

Invasive species are organisms found outside their native range. When these foreign species are introduced into new ecosystems the results can be dramatic as they displace native species and cause problems that the native system cannot adapt to.

You can own one of the smallest known campo meteorites, referred to as a campo crystal.
