This material has been engineered to be chemically and mechanically similar to asteroids, and was based on the Orgueil astroid.   Orgueil is a scientifically significant carbonaceous chondrite meteorite that fell in southwestern France in 1864. Orgueil is one of five known meteorites belonging...

This ribbed shell is a fossil of the order Rhynchonellida.  These brachiopods have existed since the Ordovician period 485 million years ago. Their population was severely diminished during the Permian–Triassic extinction event 252 million years ago, but Rhynchonellida became the...
