Photograph by James L. Amos The iconic arthropods of the Cambrian were the trilobites, which left a huge number of fossils. Trilobites had flattened, segmented, plated bodies that helped to ...

The paper, "Rapid volcanic ash entombment reveals the 3D anatomy of Cambrian trilobites," was published in the journal, Science. The trilobites, from the Cambrian period, have been the subject of ...

But his heath failed and he died, leaving around half of the trilobites then known from Britain unclassified; the work was wound up in 1883. Though unfinished, Salter's monograph has thirty excellent ...

The trilobite, an extinct marine arthropod vaguely resembling a horseshoe crab, inhabited the primordial seas that covered New England during the Cambrian period 500 million years ago. Skehanos is of ...

The new trilobite fossils are Cambrian in age (around 509 million years old) and preserved as undistorted three-dimensional molds within fine volcanic ash, not unlike the human bodies entombed at ...

They were already well diversified as soon as they appeared as part of the Cambrian "explosion", the relatively short period of evolutionary history where a huge radiation of multicellular life forms ...

The authors present 16 new well-preserved specimens from the early Cambrian Chengjiang biota ... in support of a new interpretation of the homology of dorsal sutures in trilobites and their relatives.

My analysis demonstrated that, instead of vicariant events, jump dispersal (‘founder-events’) played a prominent role in explaining the biogeography of trilobites throughout the Cambrian ...

Acanthomeridion serratum from the Cambrian Stage 3 Chengjiang Biota ... (b) Ventral plates considered homologous to trilobite doublure. (c) Ventral plates not considered homologous to any artiopodan ...
