Essexella is an extinct genus of cnidarian known from Late Carboniferous fossils; it contains a single species, E. asherae. It is one of the most recurrent organisms in the Mazon Creek fossil beds of Illinois;[1] in the Essex biota of Mazon Creek, it consists of 42% of all fossil finds.[2] Essexella was originally described as a jellyfish,[3] but was recently redescribed as a sea anemone. The scientists on the "anemone" side of the debate made a book as early as 2017,[4] but it was ignored until the same authors made a proper scientific paper in 2023.[5]
Another alleged jellyfish, Reticulomedusa, is likely Essexella preserved from different angles. Essexella may have produced the common trace fossil Conostichus.[6]
