Lobe-finned fish research[]
- A coelacanth specimen belonging or related to the species Heptanema paradoxum is described from the Ladinian Meride Limestone (Switzerland) by Renesto, Magnani & Stockar (2021), representing the first known coelacanth specimen from the Middle Triassic that undoubtedly bears elongate thin ribs.[125]
- Fossil material of mawsoniid coelacanths is described from the marine Rhaetian Bonenburg locality (Germany) by Hartung et al. (2021), who interpret this finding as indicating that mawsoniids were already present in Europe in the Late Triassic, and that they inhabited marine environments at the end of the Triassic.[126]
- Fossil material of a member of genus Mawsonia is described from the Cenomanian Woodbine Formation (Texas, United States; representing the first Cretaceous North American mawsoniid coelacanth reported to date) by Cavin et al. (2021), who evaluate the implications of this finding for the knowledge of potential factors that might have made long survival of the genera Mawsonia and Latimeria possible.[127]
- An ossified lung of a mawsoniid coelacanth is described from the Maastrichtian of Oued Zem (Morocco) by Brito et al. (2021), representing the last known record of a Mesozoic coelacanth and the first known occurrence of coelacanths in the phosphate deposits of North Africa.[128]
- A study on the evolution of feeding modes among tetrapodomorphs, as indicated by the anatomy of the skull of Tiktaalik roseae, is published by Lemberg, Daeschler & Shubin (2021), who report the simultaneous occurrence of anatomical modifications of the skull for prey capture through biting, as well as joint morphologies suggestive of cranial kinesis that is also present in suction-feeding fish.[129]
- A study on the phylogenetic relationships of extant and fossil coelacanths is published by Toriño, Soto & Perea (2021).[130]
- A study on the morphology and histology of the scales of Miguashaia bureaui, and on its implications for the knowledge of the evolution of the squamation in coelacanths, is published by Mondéjar-Fernández et al. (2021).[131]
- New fossil remains representing one of the largest known coelacanths ever reported are described from the Middle Jurassic of Normandy (France) by Cavin et al.

General research[]
- A study on the morphology of the earliest osteocytes in Tremataspis mammillata and Bothriolepis trautscholdi is published by Haridy et al. (2021), who interpret their findings as indicating that the earliest known osteocytes in the fossil record had similar morphology and likely similar physiological capabilities to their modern counterparts, and attempt to determine initial driver favoring evolution of cellular (osteocytic) over acellular (anosteocytic) bones in vertebrates.[135]
- Two Permian fish assemblages consisting of cartilaginous fishes and ray-finned fishes are reported from the Madumabisa Mudstone Formation (Zambia) by Peecook et al. (2021), who compare these assemblages with middle and late Permian freshwater fish faunas from Australia, Brazil, Chile and South Africa.[136]
- A middle Miocene freshwater fish fossil fauna is described from the Castilletes Formation (Colombia) by Ballen et al. (2021), report the presence of members of fish groups known from extant Amazonian faunas east of the Andes but absent from faunas west of the Andes, and interpret their presence as evidence that the riverine systems of the Guajira Peninsula were connected to Amazonia during the middle Miocene.[137]
