| Abstract: | Eleven specimens of the lobster Meyeria magna from the Simití Formation (Santander Province, Colombia) represent a new occurrence for this species in South America. Ammonites collected both below and above the bed that yielded M. magna allow dating of these specimens as early Albian. Morphological characteristics observed in these Colombian specimens were compared with those of other specimens from Mexico, the United Kingdom and Spain. Our interpretation of the cuticular structure in thin section does not unambiguously allow interpretation of the specimens studied to corpses or molts. |
