Hi, nice to meet you! My name is Magnita. A few days ago, I was taking a walk along Samborombón Bay. It’s a beautiful place in Argentina (Fig. 1), there are many canals and rivers that empty into the Atlantic Ocean. When I was walking, I looked at the river bank, and something surprised me. In the sediment, I could see a line of marine shells. Wow! That was surprising because I wasn’t anywhere near the sea! I wondered: how did these shells get here? Do you know what could have happened? I had no idea.
