As seen on #Cosmos: Nakhla meteorite, Martian rocks found here on Earth!
This shows two possible fossilized Martian cells and the fragments of others. The cell in the center has the remains of a fossilized biofilm partly covering its surface. The cell to the right is partly embedded in the clay mineral which fills veins or cracks in the meteorite (NAKHLA). This clay mineral is now known to have formed on Mars about 700 million years ago. If these bumps are truly fossilized Martian microbes, they are then about 700 million years old.
