👉 Macrouroidinae are a group of extinct, short-lived arthropods that lived during the Mesozoic Era (245 million years ago to about 66 million years ago). This group includes several species known as "Macrowaves," which were characterized by their long, slender bodies and large eyes. These animals were primarily terrestrial and had a streamlined body shape, with a short snout, sharp claws, and a lack of appendages that are typical for arthropods
