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 deduced about its evolutionary relationships. In particular, the new coelacanth is most similar to one member of...
