During the last 30 years there has been considerable research interest in fossil and living brachiopods, generating some, as yet, unanswered questions about these marine invertebrates. This volume brings some of these questions before zoologists and paleaontologists where they will be discussed and set within, or contrasted with, pre-existing knowledge.
