A revision of paradoxidid trilobites reveals that previous identifications of specimens from Sardinia and Spain as the Nordic trilobite species Paradoxides brachyrhachis Linnarsson, 1883, are mistaken. The southern species, occurring also in France, is here referred to Eccaparadoxides mediterraneus (Pompeckj, 1901). Main differences are seen in the preocular field, pleural furrow and pygidium. The species P. brachyrhachis is referred with question to the genus Mawddachites Fletcher 2007. 

Intraspecific Variability in Paradoxidid Trilobites from the Purujosa Trilobite Assemblage (Middle Cambrian, Northeast Spain)

Analysis based on a pooled sample of 500 specimens demonstrates that many of the characters that have been used to define these species show continuous variations, which suggests that the taxonomic classification of other paradoxidids may be oversplit.

Enrollment and thoracic morphology in paradoxidid trilobites from the Cambrian of the Czech Republic

Abstract The discovery of the partially enrolled specimens of large, late holaspid specimens of paradoxidid trilobites Paradoxides paradoxissimus gracilis, Hydrocephalus minor and Acadoparadoxides

A new look at Eccaparadoxides (Cambrian, Trilobita) and its biostratigraphic significance

Eccaparadoxides is a geographically widely distributed trilobite genus that occurs in the middle part of the Cambrian System. However, the systematically important morphologic characteristics that

Taphonomy and Palaeoecology of multi-element skeletoninvertebrates: a genetic model for exceptional preservation

The aim of the research is to improve the understanding on the origin of fossil accumulations by investigating their taphonomic and sedimentological features and by using stratigraphic data and the

The middle Cambrian cosmopolitan key species Lejopyge laevigata and its biozone: new data from Sweden

The middle Cambrian Lejopyge laevigata Zone is poorly exposed in Scandinavia. Both this zone, however, and the succeeding Agnostus pisiformis Zone are well exposed at a classic locality at Gudhem,

Correlating the Zones of 'Paradoxides hicksii' and 'Paradoxides davidis' in Cambrian Series 3

The zones of Paradoxides hicksii and P. davidis incorporate the more-widely recognised agnostid atavus to punctuosus zones and contain a suite of polymerid trilobites commonly associated with

Interpretation of tectonically deformed fossils

Abstract Taxonomic information can be recovered from tectonically deformed fossils by analysing the strain and then restoring the fossils to their original shapes. Trilobites and graptolites are used
