👉 Cyclospondylous is a scientific term used to describe a type of vertebrate that has fused bones within its skeleton. These bones are called "cyclical" because they have a regular pattern in their arrangement, with each bone forming a ring around the other ones. This is known as the "cycloplemma," and it is often seen in animals like birds and reptiles. Cyclospondylous vertebrates can be found in many different groups of animals,
