This group specialises in analysing the Palaeozoic biota recorded in different marine and transitional environments, integrating the diverse palaeontological data in the construction of a biostratigraphic scale of the highest possible precision, allowing for global correlations to be integrated and contributing to the elaboration of the International Stratigraphic Chart. These data are also used in the recognition of Events (Geo and Bio, local and global), and in paleoecological, paleoclimatic and paleogeographic reconstructions. The members of the group are international leaders in the Cambrian and Devonian Systems, as attested by the fact that Professors Gozalo and Valenzuela are Full Members (with voting rights) of the International Subcommissions on Cambrian and Devonian Stratigraphy respectively. Dr. Liao is also a Corresponding Member of the International Sub-Commission on Devonian Stratigraphy. Another aspect that manifests this leadership is the recent organisation of a triple International Congress at the Universitat de València in which all members of the Group participated, Prof. Valenzuela being the President of the Congress and Dr. Liao the Secretary General.

Another aspect that manifests this leadership is the recent organisation of a triple International Congress at the Universitat de València in which all members of the Group participated, Prof. Valenzuela being the President of the Congress and Dr. Liao the Secretary General. Last but not least, all four members have been involved in synthesising papers on the respective Cambrian and Devonian systems in prestigious journals and books. The main scientific and technical objectives are as follows:
Detect the existence of Global Events in selected Palaeozoic sections of Spain, France, Germany, Italy, Austria, Czech Republic, Mongolia, Siberia, Uzbekistan, Morocco, China and the United States.
Detect the existence of Global Bioevents in different groups of macro and microfossils, mainly in trilobites, brachiopods, conodonts, fish, ostracods and plants (macrofossils and spores).
To make high-resolution correlations between the biostratigraphic scales provided by the fossil groups mentioned above.
Identify the boundaries of the Cambrian and Devonian Series and their Floors in selected sections and refine their study according to the agreements and criteria of the International Commission on Stratigraphy and the two corresponding sub-commissions (Cambrian and Devonian).
Compare the data obtained in Spain with those of the other regions mentioned above.
To elaborate a standard reference scale for the Cambrian and Devonian of Spain to serve as a world reference.
Tracing neritic and pelagic successions in order to refine and intercalibrate regional biostratigraphic scales.
Coordinate with other national and, mainly, international groups to carry out interdisciplinary studies, mainly geochemical, geophysical and cyclo-stratigraphic studies that integrate and complement biostratigraphic studies.
