👉 Microhypnum is a type of plant found in the Albian period, approximately 450 million years ago, during the early stages of the Earth's history. This microhypothenanum was characterized by its small size and the presence of a single cell. It is known for its unique stem-like structure that allows it to grow very quickly due to its limited space. The term "microhypnum" likely refers to this unique feature.
