'The book's strengths are several. The editors had a clear idea of what they wanted from their interdisciplinary encounter and they framed the process with welcoming introductory chapters and a masterly concluding one. Ethologists will find accessible even the most esoteric data … most chapters make a real effort to be understood by non-specialists … this is a brave and provocative book. It is a call to arms for true-disciplinary collaboration. Few ethologists know palaeontology, but all will learn from this bridge-building effort.' Ethology
