👉 Acanthodinoids are a group of extinct plant species that lived during the Mesozoic era, around 256 million years ago. These plants were characterized by their distinctive leaves and stamens, which often had three or four lobes, forming a net structure to trap pollen grains. The Acanthodinoid family is known for its extensive distribution across various regions of the world, including Africa, Asia, and Australia.
