ELI5: Explain Like I'm 5

Ikaria wariootia

Ikaria wariootia is a very old and small creature that used to live a long, long time ago. It was really tiny, about the size of a grain of rice, and it lived in the sand at the bottom of the ocean.

The creature had a little tube-like body that looked like a worm and it had a pointy head with a tiny mouth. This little creature would wiggle its way through the sand and eat tiny particles of food that it found there.

Scientists found some fossils of Ikaria wariootia, which basically means they found the remains of this tiny creature in the sand that had turned into a rock. They were very excited about this discovery because it helped them learn more about what life was like a really long time ago in the ocean.
