Myodocopa

Although the carapace of myodocopans is poorly calcified, some fossils are known for the group. (In contrast, thousands of fossil species are named for the Podocopa). Of particular interest are those fossils for which the internal body parts (and not just the carapace) are preserved. This provides a lot more information about the likely relatives to the fossil taxa, including relatives still alive today. Two recent fossils of much interest have been found from Silurian deposits (dated at 425 million years ago). These fossils have well preserved internal body parts.
