| Shell disintegration and taphonomic loss in rudist biostromes. |
| The limestone clasts contain rudist fragments and larger foraminifera that indicate erosion from the Campur Formation. |
| The seas were inhabited by large ammonoids like Olcostephanus, bivalves like Bruchia, and some of the early rudist reefs. |
| This member contains abundant and diverse mid-Cretaceous shallow-marine invertebrates, including reef corals and rudist bivalves. |
| Most of the rudist species listed by these authors are typical late Albian taxa, but their purported occurrences here require additional study and supportive documentation. |
| Many rudist species were defined on specimens collected from the El Abra Formation in Mexico, a widespread carbonate platform. |
