Glossary of fossil tetrapod tracks

Abstract

The terminology used in fossil tetrapod track research has expanded and evolved considerably in recent decades. The main drivers of this change are conceptual and methodological advances, the emergence of distinct subfields such as hominin track research, and increased interdisciplinarity. This growing lexicon has led to confusion and conflict, as long-standing usage of terms has been questioned (e.g., the term “preservation”) or conflicts with the terminology of related fields such as invertebrate ichnology and biomechanics (e.g., the terms “elite track/trace” and “pace gait”). In addition, the definition of a number of key terms, including the term “track” itself, has remained vague. The present glossary provides a comprehensive review of the terminology used in tetrapod track research. In addition to documenting past usage of terms, we aim to provide a standard terminology that is 1) precisely defined, unambiguous, and consistent; 2) compatible with terminology used in related fields; 3) reflects current knowledge and is not misleading, and 4) is easily understood and follows traditional usage as much as possible. In addition to terminology, we also aim to briefly explain and discuss the concepts and methods behind each term, and, where appropriate, refer the reader to the relevant literature.
