Diplochaetetes is an extinct genus of marine polychaete worms in the family Cirratulidae.[1] It was initially described as a tabulate coral,[2] and later classified as a sponge.[3] Later studies provided significant evidence that Diplochaetetes fossils are bioconstructions attributable to cirratulid polychaetes due to their strong similarity with modern Dodecaceria aggregates.[4][5][6] Both fossil Diplochaetetes and recent Dodecaceria bioconstructions retain identical double-phased biomineralization characteristics, but the possible synonymity of these genera is currently subject to debate.[7]

Fossil record edit
Main article: Cirratulidae fossil record
The first Diplochaetetes fossils were discovered in Namibian sediments dating back to the Eocene.[2] No known Paleocene record has been described, but from the Oligocene onwards, aggregates are found in the pacific coasts of the Americas.[3][8] It's worth noting that recent bioconstructions are attributed to the genus Dodecaceria.[6]
Species edit
The following species are currently recognised in the genus Diplochaetetes:[1]
- Diplochaetetes longitubus † Weissermel, 1913
- Diplochaetetes longitubus vermicularis † Weissermel, 1926
- Diplochaetetes mexicanus † Wilson, 1986
