Without this donation our knowledge of placodont material from the Algarve would be much poorer. We want to thank Geoparque Algarvensis for the support and promotion of this work. We want to thank Dinopark Lourinhã for enabling access to Dinopark’s preparatory lab, helping in the process of preparation of the fossil material. We thank S. Mateus, J. Marinheiro, and V.
