| Abstract: | The first record of the superfamily Trigonioidoidea (Order: Unionoida) from the Lower Cretaceous of Teruel, Spain is described and compared to known taxa from Europe and Asia. This is a new record of the Trigonioidoidea from Europe, following material described from the Barremian of the Isle of Wight (southern England) and Aptian-Barremian from Iberian Range (Spain). The new material, recorded from the Albian of the Escucha Formation (“Barriada” Member) in Utrillas (Teruel, northeastern of Spain), comprises four specimens. Analysis of the main morphological characters including anterior musculature, dentition, and ornamentation indicates that this material constitutes a new genus and species, Iberanaia iberica. The palaeoenvironment in which the bivalves lived corresponds to a fluvial-palustral setting connected to a deltaic system. |
