The Fossils of the Burgess Shale
THE ROLE OF DECAY AND MINERALIZATION IN THE PRESERVATION OF SOFT-BODIED FOSSILS
▪ 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.…
Controls on the formation of authigenic minerals in association with decaying organic matter: an experimental approach
Carcasses of the shrimp Crangon crangon were incubated in a marine medium under oxic conditions at 15°C which was inoculated with a consortium of sulfate-reducing, sulfide-oxidizing, and fermentative…
Taphonomy of insects in carbonates and amber
Abstract The major taphonomic processes that control insect preservation in carbonate rocks (limestones, travertines and nodules) are biological: insect size and wingspan, degree of decomposition,…
Ordovician faunas of Burgess Shale type
TLDR
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
TLDR
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.
Plumage Color Patterns of an Extinct Dinosaur
TLDR
This work has reconstructed the appearance of a theropod dinosaur by mapping features of its well-preserved feathers and comparing them with modern samples from birds, and indicates that the body was gray and dark and the face had rufous speckles.
The Largest Cambrian Animal, Anomalocaris, Burgess Shale, British Columbia
TLDR
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.
The Cambrian evolutionary ‘explosion’: decoupling cladogenesis from morphological disparity
TLDR
Evidence is presented that the important events in the generation of clades were earlier than the Cambrian ‘explosion’, at which time the groups become manifest in the fossil record.
