A Devonian tetrapod-like fish and the evolution of the tetrapod body plan

Daeschler, Edward B., Shubin, Neil H., Jenkins, Farish A.·2006·Nature

Abstract

The relationship of limbed vertebrates (tetrapods) to lobe-finned fish (sarcopterygians) is well established, but the origin of major tetrapod features has remained obscure for lack of fossils that document the sequence of evolutionary changes. Here we report the discovery of a well-preserved species of fossil sarcopterygian fish from the Late Devonian of Arctic Canada that represents an intermediate between fish with fins and tetrapods with limbs, and provides unique insights into how and in what order important tetrapod characters arose. Although the body scales, fin rays, lower jaw and palate are comparable to those in more primitive sarcopterygians, the new species also has a shortened skull roof, a modified ear region, a mobile neck, a functional wrist joint, and other features that presage tetrapod conditions. The morphological features and geological setting of this new animal are suggestive of life in shallow-water, marginal and subaerial habitats.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The first land invasion of fish ancestors occurred during the late Devonian period, approximately 370 million years ago.

    “The first land invasion of our fish ancestors is considered to have occurred during the late Devonian period ~370 million years ago (Mya) (Daeschler et al., 2006).”
  • Geological and anatomical evidence is strongly indicative that Tiktaalik was an animal interacting with the substrate in an aquatic context.

    “Geological and anatomical evidence is strongly indicative that Tiktaalik was an animal interacting with the substrate in an aquatic context (12, 42, 43).”

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.
