Overview of the (partially interpreted) taphonomic situation and exhibition setting of Argovisaurus martafernandezi (PIMUZ A/III 5279). A overview of all the restored blocks restored as exhibited. B interpretative drawing of the overview showing the separately collected blocks. Notes: The exact location of blocks 1 and 5 is unknown, they have been restored to their most logical taphonomic location. The right angular and left jugal have been separately collected and placed as best guesses © F. Miedema, D. Bastiaans, T. M. Scheyer, C. Klug & E. E. Maxwell · CC BY 4.0 · Wikimedia
