👉 Indostomids are a family of extinct marine invertebrates that lived during the Ordovician period, approximately 465 million years ago. These creatures were characterized by their large, streamlined bodies and covered skin with long, curved tentacles that could be used for a variety of tasks such as swimming, capturing prey, and foraging. Indostomids played an essential role in marine ecosystems during the Ordovician period due to their ability to thrive on small, aquatic animals.
