Morphological Disparity During the Ammonoid Recovery After the ...

The Permian mass extinction caused the elimination of 80% of marine genera. Ammonoids, however, survived the extinction and returned to the levels of ...

Ammonoid recovery after the Permian–Triassic mass extinction

Using an updated dataset of Early Triassic ammonoids, we compare morphological disparity and taxonomic richness patterns at the regional and ...

Ammonoid recovery from the Late Permian mass extinction event

Morphological analysis indicated that ammonoids did not fully recover until the Spathian or Anisian. Taxonomic diversity is a poor predictor of disparity during ...

Ammonoid taxonomic and morphologic recovery patterns after the ...

During the third stage (Smithian), morphologic diversity returned to Griesbachian levels. The loss of representatives from two morphologically ...

Morphological fluctuations of ammonoid assemblages from the ...

These morphological discontinuities are synchronous with immigrations into the Germanic Basin of crinoid and brachiopod taxa. This discovery indicates ...

Paleozoic ammonoid ecomorphometrics test ecospace availability ...

Instead, during this richness recovery, residual disparity was lower than at any other time in the Paleozoic, dropping below the null 90% range ...

The complex effects of mass extinctions on morphological disparity

We find no simple null for disparity change following a mass extinction but do observe general patterns. The range of trait values decreases following either ...

Decoupling of morphological disparity and taxonomic diversity ...

Diversity decoupled from ecosystem function and resilience during mass extinction recovery. ... Ammonoid recovery after the Permian ...

DISPARITY: MORPHOLOGICAL PATTERN AND ...

Underlying this concern with disparity is a question about temporal variation in the production of morphological innovations, a debate over the ...

Taxonomic Diversity and Morphological Disparity of Paleozoic ...

The changes in both are tracked through many extinction events, some of these events nearly brought about the end of the ammonoids. Recovery periods after ...

Morphological variability in response to palaeoenvironmental change

Changes in ammonite morphology during the earliest Early Aptian (Cretaceous) of an epicontinental sea in northern Germany were investigated based on new and ...
