A guide to the nomenclature of heterochrony
Since Haeckel's Biogenetic Law (‘ontogeny recapitulates phylogeny’) fell into disrepute early in the twentieth century, there has been intermittent debate, particularly in recent years (de Beer,Expand
Arthropods invade the land: trace fossils and palaeoenvironments of the Tumblagooda Sandstone (?late Silurian) of Kalbarri, Western Australia
The trace fossils of the Tumblagooda Sandstone (?late Silurian) of Kalbarri, Western Australia are spectacular in their variety and preservation. They provide a unique insight into the activities ofExpand
Heterochrony: The Evolution of Ontogeny
The authors outline evolutionary thought from pre-Darwinian biology to current research on the subject. They broadly label the factors of evolution as intrinsic and extrinsic, with Darwin favoringExpand
Maastrichtian non-heteromorph ammonites from the Miria Formation, Western Australia
Twenty-two species of non-heteromorph ammonites, distributed among fourteen genera, are described from the Miria Formation, Western Australia. The species Kitchinites spathi, Gunnarites raggatti,Expand
End-Permian extinction and subsequent recovery of the Ophiuroidea (Echinodermata)
A worldwide stratigraphical survey of Late Palaeozoic and Early Mesozoic ophiuroids (Echinodermata) reveals unique extinction and recovery patterns during and after the end-Permian mass extinctionExpand
Maastrichtian heteromorph ammonites from the Carnarvon Basin, Western Australia
A comprehensive taxonomic revision of heteromorph ammonites from the Miria Formation and the uppermost horizon, a nodule bed, of the Korojon Calcarenite is presented, with major rationalisation ofExpand
ONTOGENY AND HETEROCHRONY IN THE EARLY CAMBRIAN ORYCTOCEPHALID TRILOBITES CHANGASPIS, DUYUNASPIS AND BALANGIA FROM CHINA
TLDR
The relative degree of ontogenetic variation within the lineage Duyunaspis duyunensis–Balangia balangensis is analysed and indicates that Balangia may have evolved from Duy unaspis by paedomorphosis, supporting the view that the Oryctocarinae may be considered as paedomedomorphic descendants of the Oyctocephalinae.

THE ROLE OF HETEROCHRONY IN THE EVOLUTION OF CAMBRIAN TRILOBITES
TLDR
This review highlights the importance of heterochrony in the evolution of the Metazoa in the role of changes to developmental regulation in organisms. Expand
