Slab surfaces of two splitted rhodoliths showing their inner arrangement and the trace fossils; Cabo de Gata. Each rhodolith was cut in two parts through its center. Note that the Gastrochaenolites specimen (G; comparable to G. lapidicus Kelly and Bromley; dashed lines) still contains its producer boring bivalve (Gastrochaena sp.), which grew in encrusting (en) and lumpy (lu) coralline growth forms. The rhodolith shape is not influenced by the boring-bivalve shape
