Trilolab is a collective of people that are involved with the various aspects of trilobites. Our primary focus is the Devonian of the Ardenno-Rhenish Mountains (Belgium, Luxemburg, France and Germany) and southern Morocco.

​We do not claim to be an academic research lab. Rather, we are a non-profit workgroup aiming to collaborate and share knowledge by means of fieldwork, education and (research) articles. Trilolab is a dedicated workgroup of Palaeontologica Belgica
