Monostychia is an extinct genus of prehistoric sand dollar (a highly flattened type of sea urchin) that thrived in the shallow coastal waters of southern Australia millions of years ago.First named by Gustav C. Laube in 1869, these marine invertebrates are part of the order Clypeasteroida. Their robust calcite shells preserve beautifully in limestone formations, making them a staple find for paleontologists and amateur fossil collectors across the country
