ABSTRACT An unusual fork-tailed coelacanth from the Lower Triassic Sulphur Mountain Formation of British Columbia, Canada, marks the first considerable departure in actinistian body form since the Mississippian Period. Rebellatrix divaricerca, gen. et sp. nov., is unique among coelacanths in its possession of a bifurcated caudal fin, reduced segmentation of fin rays, and fusion of caudal fin elements. Parsimony analysis of a character-taxon matrix of 109 characters and 29 taxa recovered R… Expand
New Early Triassic coelacanth in the family Laugiidae (Sarcopterygii: Actinistia) from the Sulphur Mountain Formation near Wapiti Lake, British Columbia, Canada
A new Early Triassic coelacanth, Belemnocerca prolata, gen. et sp. nov., is described as a new member of the family Laugiidae. Although only one incomplete specimen is known, much can be deducedExpand
New coelacanth material from the Middle Triassic of eastern Switzerland, and comments on the taxic diversity of actinistans
New coelacanth material from the Middle Triassic Prosanto Formation of the Ducan and Landwasser area near Davos in eastern Switzerland, Canton Graubünden, is described. A sub-complete individual isExpand
The Giant Cretaceous Coelacanth (Actinistia, Sarcopterygii) Megalocoelacanthus dobiei Schwimmer, Stewart & Williams, 1994, and Its Bearing on Latimerioidei Interrelationships
TLDR
The cladistic analysis supports the sister-group relationship of Megalocoelacanthus and Libys within Latimeriidae and suggests that toothless, large-sized coelacanths evolved independently in both Latimer iidae and Mawsoniidae during the Mesozoic. Expand
A microanatomical and histological study of the scales of the Devonian sarcopterygian Miguashaia bureaui and the evolution of the squamation in coelacanths
TLDR
The scales of Miguashaia bureaui are described, revealing histological data for a Palaeozoic coelacanth in great detail and adding to the authors' knowledge on the dermal skeleton of sarcopterygians. Expand
First Occurrence of a Mawsoniid Coelacanth in the Early Jurassic of Europe
ABSTRACT Coelacanths form a clade of sarcopterygian fishes (lobe-finned vertebrates) that today is represented by a single genus, Latimeria. This genus belongs to a lineage of marine coelacanths, theExpand
A New Fossil Actinistian from the Early Jurassic of Chile and Its Bearing on the Phylogeny of Actinistia
ABSTRACT We present the description and taxonomic reassignment of a new genus and species, Atacamaia solitaria, gen. et sp. nov., from Lower Jurassic strata of northern Chile, South America. TheExpand
A review of the Carboniferous lungfish genus Ctenodus Agassiz, 1838 from the United Kingdom, with new data from an articulated specimen of Ctenodus interruptus Barkas, 1869
  • E. Sharp, J. Clack
  • Biology
  • Earth and Environmental Science Transactions of the Royal Society of Edinburgh
  • 2013
TLDR
Ctenodus is the longest-surviving genus of lungfish from the carboniferous, and the only one to cross the Lower–Upper Carboniferous boundary, and five species span the period, with species correlated to stage. Expand
Dobrogeria aegyssensis, a new early Spathian (Early Triassic) coelacanth from North Dobrogea (Romania)
TLDR
Ossifications of the lower jaw, together with branchial and pectoral elements, complete the description of this coelacanth and support the coining of a new generic and specific name, Dobrogeria aegyssensis. Expand
Characterization of coelacanth scales from the Early Cretaceous freshwater locality of Las Hoyas, upper Barremian (Cuenca, Spain)
Coelacanths are rare, mostly marine fishes, but the species from the Lower Cretaceous Spanish locality of Las Hoyas (Barremian) is a freshwater form and we know almost nothing about it. The Las HoyasExpand

A NEW COELACANTH (ACTINISTIA, SARCOPTERYGII) FROM THE JURASSIC OF FRANCE, AND THE QUESTION OF THE CLOSEST RELATIVE FOSSIL TO LATIMERIA
TLDR
A cladistic analysis suggests that the new species is the fossil sister taxon to Latimeria, but this close relationship is weakly supported and Nevertheless, Wenzia latimerae belongs with confidence to the Latimeriidae. Expand
Helmolepis cyphognathus, sp. nov., a new platysiagid actinopterygian from the Lower Triassic Sulphur Mountain Formation (British Columbia, Canada)
A new species of stem actinopterygian, Helmolepis cyphognatus sp. nov., is reported from the Lower Triassic Sulphur Mountain Formation of western Canada (probably Smithian). This taxon differs fromExpand
A newly recognized fossil coelacanth highlights the early morphological diversification of the clade
TLDR
Coelacanths have long had an iconic place in the study of vertebrate evolution for their apparent anatomical conservatism over geological time, but Holopterygius provides clear evidence for rapid morphological evolution early in the history of this clade. Expand

A fiftieth anniversary reflection on the living coelacanth, Latimeria chalumnae: some new interpretations of its natural history and conservation status
TLDR
For this year's 50th anniversary of the famous discovery of the first living coelacanth, retraced the routes and visited the main actors of this zoological drama, facilitated by novel interpretation of earlier data and expeditions to the Comoro Islands. Expand
THE CAUDAL FIN AS A HYDROFOIL
TLDR
The recent cytological findings confirm the Schraders' hypothesis that the lecanoid system of chromosomal behavior can provide the basis or the "raw material" for the evolution of haplodiploidy in the coccids. Expand
Early growth stages in coelacanth fishes.
TLDR
It seems more reasonable to interpret this fossil specimen from the Upper Jurassic of Solnhofen, southern Germany, as a cannibal that had just swallowed two young of its own kind, and this interpretation is favoured by the position of the two specimens. Expand
