Vertebrates do not have exoskeletons. However, they do have internal organs, vertebral columns, and tails. Lampreys are vertebrates that also do not have jaws.
Why are the fossils of vertebrates similar to the bones of living vertebrates?
Fossils of vertebrates are similar to the bones of living vertebrates because they were once part of living organisms that shared similar anatomical structures and functions. Over time, the bones of vertebrates have undergone evolutionary changes, but many core features have been conserved due to their essential functions. This similarity allows paleontologists to make informed comparisons and infer the evolutionary relationships between ancient and modern vertebrates.
