Dodecaceria

Dodecaceria is a genus of marine polychaete worms in the family Cirratulidae.^[1] It's also one of the very few polychaete genera with a verified fossil record.

Fossil record

Further information: Cirratulidae § Fossil record

The earliest species on record, Dodecaceria cretacea (Voigt, 1971), later reclassified as the ichnofossil Caulostrepsis cretacea, was responsible for leaving boring traces on Late Cretaceous coral reefs.^[3] Authors such as Fischer et al. (1989,^[4] 2000^[5]) have proposed that Diplochaetetes fossil bioconstructions may be attributed to Dodecaceria due to synonymity. A research by Guido et al. (2024)^[6] reported very similar double-phased biomineralization processes in bioconstructions attributed to these genera.
