Diplochaetetes longitubus is an extinct species of cirratulid polychaete within the genus Diplochaetetes known from Namibian sedimentary rocks dating back to the Eocene.[1] It was initially described as a tabulate coral, but research carried out on present-day Dodecaceria aggregates and Diplochaetetes mexicanus fossils from the pacific coasts of the Americas has led researchers to classify the entire genus as cirratulid polychaetes.[2][3][4] For many decades, they've also been erroneously attributed to sponges.[5]
A subspecies named Diplochaetetes longitubus vermicularis was also later described from Eocene Namibian sediments.[6]
Although present-day Dodecaceria and fossil Diplochaetetes aggregates from Peru have been confirmed to show identical double-phased biomineralization characteristics,[7] no detailed analysis has been performed on their Namibian counterparts so it's unclear whether the trait is shared on a broad genus basis.
