Trilobites and intercontinental tie points in the Upper Cambrian of Scandinavia [PDF]
The Upper Cambrian faunas of Scandinavia are generally dominated by olenid trilobites, which provide a firm basis for the biostratigraphic classification. The olenids tend, however, to be provincial and facies controlled.

Review of the Cambrian Stratigraphy of the Argentine Precordillera
The Cambrian rocks of the Argentine Precordillera are analyzed and updated providing a new stratigraphic interpretation. The lithostratigraphic assemblages provide evidence that the Precordilleran Cambrian Basin was a rimmed platform.

Trilobite compound eyes with crystalline cones and rhabdoms show mandibulate affinities
Little is known about the internal anatomy of early eyes. Here, Scholtz and colleagues show the internal eye structures from fossils of two genera of trilobites, which support an ancestral apposition eye with crystalline cones in Trilobita and a close ...
