Born in Belgium in 1966, Luc graduated as an engineer in polymer technology. His interest for fossils started at an early age of 12 when he was given a book on fossil collecting. It was not long after this that fossil hunting became his passion, starting with the collecting of ammonites and trilobites in France. In 2004, his passion resulted in his first active participation in the exhibition ‘Leven in Steen’ (Life in Rocks), a collaboration between the Belgian Museum of Natural History and the University of Leuven. Through his career in international oil and gas industry which led to extensive travelling, Luc has built contacts with museums and specialists in palaeontology all over the world. Luc is a keen collector and preparator of fossils. It is his passion for trilobites that brought him in contact with the ‘Back to the Past’-team. With his connections and contacts, Luc hopes to participate in the further development of the ‘Back to the Past’ project.

Born in Saint-lô in 1977 (Normandy, France), Dr. Rudy Lerosey-Aubril has followed undergraduate studies of Natural History at the University of Caen and Rennes, before he obtained a Master degree (2001) and a Doctor degree (2004) in Palaeontology at the University of Montpellier. After his doctoral studies, he has been assistant professor (substitute) at the University Montpellier II (2004-2005) and the University of Clermont-Ferrand (2006-2007). Since 2009, he has been the leader of the section Palaeozoology 1 (‘Aquatic macroarthropods’) at the Senckenberg Research Institute in Frankfurt am Main (Germany). His main research topics concerns the palaeobiology and palaeoecology of ancient arthropods, the preservation of soft tissues, and the ontogeny and the late evolutionary history (Late Devonian-Permian) of trilobites. As a section leader, he is in charge of large collections of fossil invertebrates (>170 000 specimens), including one of the most important collections of trilobites of the world (>122 000 specimens).
Since 2005, Dr. Lerosey-Aubril has authored or co-authored some twenty articles or book chapters on trilobites and presented many conferences or posters on these fascinating fossils in scientific meetings, including the 2nd German Trilobite Symposium he has co-organized in 2011 in at the Senckenberg Museum.

Joan was born in 1958 in Berga, a mining town in Barcellona Province (Spain), and now lives in Sabadell. His passion for fossils began at age eight and has never diminished. He is a member of the Société Espagnole de Paléontologie (Spanish Paleontological Society) and is responsible for the identification of trilobites for the Musée Géologique du Séminaire de Barcelone (Geological Museum of the Seminary of Barcellona).Although skilled in general paleontology, he now specializes in Moroccan trilobites.

Since 2007 he has been studying undescribed Ordovician trilobites found in newly discovered moroccan sites. He is also the administrator and director of the Fosilart Company.
