Funding Information: We would like to thank anonymous reviewers for providing a detailed and very constructive review, contributing to the enhancement of the manuscript. We express our great gratitude to J. Graça for donating the skull ML. A9182 to the Museu Municipal de Loulé, making this study possible. 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.

We would also like to thank C. Pessoa for helping with XRF analysis at the Departamento de Ciências da Terra of Faculdade de Ciências e Tecnologia of Universidade Nova de Lisboa.
