The Cambrian Fossil Record and the Origin of the Phyla

Budd, G. E.·2003·Integrative and Comparative Biology

Abstract

Whilst the "Cambrian Explosion" continues to attract much attention from a wide range of earth and life scientists, the detailed patterns exhibited by the terminal Proterozoic-Early Cambrian biotas remain unclear, for reasons of systematics, biostratigraphy and biogeography. In particular, recent changes in absolute dating of the Cambrian have refined the period of time that the fossil record might be of most help in revealing the dynamics of the undoubted radiation taking place at this time. The famous exceptionally preserved faunas seem to be rather close temporally, and as yet reveal little about the earliest and critical period of evolution, deep in the Cambrian. Nevertheless, the most parsimonious interpretation of the Cambrian fossil record is that it represents a broadly accurate temporal picture of the origins of the bilaterian phyla.

  • The first appearances of early Cambrian metazoan groups are clustered geochronologically by higher-rank phylogeny.

    “The first appearances of these groups are clustered geochronologically by higher-rank phylogeny (Budd, 2003; Landing & Westrop, 2004; Li et al . 2007).”

  • The clustering of first appearances reflects the true sequence of divergence of high-ranking groups and implies rather late origins, probably near the Precambrian-Cambrian boundary, followed by rapid evolutionary radiation in the early Cambrian.

    “Budd (2003) and Budd & Jensen (2000, 2003) argued that this clustering reflects the true sequence of divergence of these high-ranking groups and implies rather late origins, probably near the Precambrian-Cambrian boundary, followed by their rapid evolutionary radiation in the early Cambrian.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
