In northeastern Mexico, the Upper Jurassic to lowermost Cretaceous (Kimmeridgian–Berriasian) hemipelagic La Casita Formation is widely known for its diverse and abundant assemblage of well-preserved ammonites. Here we present specimens of KimmeridgianIdocerassp. and Tithonian “Virgatosphinctes” aff.communisSpath covered by the epizoic oysterLiostrearoemeri(Quenstedt, 1843). Attachment to both sides of the ammonite shells, taphonomic and epizoan-to-ammonite orientation analyses and shell-size measurements indicate that the oysters attached to living hosts. We interpret the presence of distinct bivalve growth cohorts at this location to reflect two generations of epizoan settlement: an initial cohort of oysters settled on the juvenile whorls of ammonites and were followed by a second set of considerably smaller individuals on the outer whorls. A pseudoplanktonic mode of life ofLiostrea roemeriattached to ammonites may reflect a strategic response to oxygen-depleted conditions near the seafloor of the Upper Jurassic La Casita Sea.L. roemeriwas previously described from Europe, also attached to ammonites.
