Er...well, I didn't mean personally remembering the landing (I wasn't 
even alive yet), but remembering that we have landed.

Technically, magma is the still molten stuff under the crust. It becomes 
lava when it leaks out onto the surface, and some form of igneous rock 
when it solidifies. Solidified lava is often called just "lava rock".
What you describe sounds like some kind of obsidian (volcanic glass) 
rich lava rock.

Shells are found in sedimentary rock, lava rock is igneous. Though it 
could be from lava that flowed into sedimentary rock, or sedimentary 
rock formed from ash and volcanic debris falling on a body of water. 
Perhaps beach sand partially melted by lava? (That would explain the 
glassiness and the shells.)
