THE ROLE OF DECAY AND MINERALIZATION IN THE PRESERVATION OF SOFT-BODIED FOSSILS

- 28 November 2003
▪ Abstract Fossil deposits that preserve soft-bodied organisms provide critical evidence of the history of life. Usually, only more decay resistant materials, e.g., cuticles, survive as organic…

Disparity as an evolutionary index: a comparison of Cambrian and Recent arthropods
Disparity is a measure of the range or significance of morphology in a given sample of organisms, as opposed to diversity, which is expressed in terms of the number (and sometimes ranking) of taxa.…

It is suggested that this animal, the largest known from Cambrian rocks, swam by using the series of closely spaced lateral lobes essentially as a lateral fin along which waves of motion were propagated.
Ordovician faunas of Burgess Shale type
The discovery of numerous diverse soft-bodied assemblages in the Lower and Upper Fezouata Formations (Lower Ordovician) of Morocco are reported, which include a range of remarkable stem-group morphologies normally considered characteristic of the Cambrian.

Anomalocaridid trunk limb homology revealed by a giant filter-feeder with paired flaps
Evidence shows that anomalocaridids represent a stage before the fusion of exite and endopod into the ‘Cambrian biramous limb’, confirming their basal placement in the euarthropod stem, rather than in the arthropod crown or with cycloneuralian worms.
Middle Cambrian Arthropods from Utah

Abstract The Middle Cambrian Spence Shale Member (Langston Formation) and Wheeler and Marjum Formations of Utah are known to contain a diverse soft-bodied fauna, but important new paleontological…
Fossilization of Soft Tissue in the Laboratory

In decay experiments modern shrimps became partially mineralized in amorphous calcium phosphate, preserving cellular details of muscle tissue, particularly in a system closed to oxygen, where organisms are rapidly overgrown by microbial mats.
