Open AccessUnexpectedly curved spines in a Cambrian trilobite: considerations on the spinosity in Kingaspidoides spinirecurvatus sp. nov. from the Anti-Atlas, Morocco, and related Cambrian ellipsocephaloids
The new ellipsocephaloid trilobite species Kingaspidoides spinirecurvatus has a spectacular morphology because of a unique set of two long and anteriorly recurved spines on the occipital ring and the axial ring o...

Open AccessChemostratigraphic correlations across the first major trilobite extinction and faunal turnovers between Laurentia and South China
During Cambrian Stage 4 (~514 Ma) the oceans were widely populated with endemic trilobites and three major faunas can be distinguished: olenellids, redlichiids, and paradoxidids. The lower–middle Cambrian boun...

Open AccessIsotopic evidence for temperate oceans during the Cambrian Explosion
The Cambrian Explosion was a key event in the evolution of life on Earth. This event took place at a time when sea surface temperatures have been proposed to reach about 60 °C. Such high temperatures are clear...

Carbon and Sulphur Isotopes from the Cambrian Series 2–Series 3 Boundary: Potential Proxies for Global Correlation?
The Cambrian Series 2–Series 3 boundary intervals of five mixed carbonate–siliciclastic successions of Gondwana, Laurentia, and Siberia were analysed for their carbonate carbon isotopes (δ13Ccarb) and sulphur iso...

Re-interpretation of a Lower–Middle Cambrian West Gondwanan ramp depositional system: a case study from the Cantabrian Zone (NW Spain)
Detailed litho- and biofacies investigations of the Lower–Middle Cambrian carbonate Láncara Formation resulted in its subdivision into nine lithofacies types: (1) claystone, (2) recrystallized mudstone, (3) la...
